Food safe epoxy is a material that is used to coat and protect food from bacteria, mold, and other contaminants. It is applied as a sealant to prevent these contaminants from entering into the food item and causing spoilage or illness.
There are many different types of epoxy available on the market, but not all of them are suitable for use with food. In order to ensure that you are using a safe and FDA-approved product, it is important to do your research before making a purchase.
This article will provide an overview of what you need to know about food safe epoxy, as well as some helpful tips on how to choose the right product for your needs.
Epoxy Resins [What Are They?]
Epoxy resins are a type of industrial resin that is used in a wide range of applications. Because they have high strength and good resistance to chemicals, the most common use for epoxy resins is as a sealant or coating.
They can be used on a variety of surfaces, including metal, wood, concrete, stone, and many more. Epoxy resins are usually mixed with another substance or material in order to produce a usable product. For food safe epoxy, it is commonly mixed with different types of pigments and solvents.
The basic raw materials for many types of epoxy resin are often obtained from petroleum refining, although they can also be made through natural chemical reactions.
Many epoxy resins also require additives to produce specific qualities, such as flexibility and the ability to flow in order to make them suitable for a particular use.
Epoxy resin performance is usually affected by the type of base material that it is mixed with and how long it takes to cure. These factors can affect the final properties of the resin and what you can use it for.
It gets the name from “epoxide,” which is a chemical structure found in some organic compounds. The material is a flexible, water-repellent substance made of carbon chains that are linked to other chemicals such as hydrogen, oxygen, or nitrogen via a covalent bond.

Food Grade Epoxy [What Exactly Does That Mean?]
When it comes to epoxy, the term “food grade” is often used in reference to products that have been specifically made for use with food. Just because an epoxy resin is labeled as being food safe does not necessarily mean that it meets all of the FDA guidelines.
It only means that it is safe to use on foods like meat, fish, vegetables, and fruit. It is not intended to be used for canned foods or anything else that needs to retain its moisture.
You should always check with the manufacturer first before using epoxy resin on food items. The ISO 22000 is a modernized version of the ISO 9001:2008 that has been designed to meet the specific needs of healthcare and non-food businesses.
The first is the FDA’s, which must be met. It also contains standards defined by the Food and Drug Administration (FDA), the Federal Office for Risk Assessment (FORA), and EU Regulation No. 10.2011, among other things.
There are actually more guidelines than just one specified term when it comes to FDA guidelines. There are three separate terms that you will see: food safe, food-contact, and FDA approved.
These regulatory terms mean that the material can be used to form a coating on either raw or processed foods without posing a health risk. The epoxy resin itself must also meet certain physical and chemical properties in order to be considered for use.
It has no flavor or fragrance when consumed. If food is eaten after coming into contact with the substance, there is no risk to human health. It does not emit any free components or significant quantities of bound components into the meal.
Is Epoxy Food Safe?
Epoxy resins are generally not toxic to the human body if they do not contain any solvents. The substance itself is considered a low hazard, but it may have components that can pose a risk depending on how it has been used and/or how pure it is.
Food safe epoxy does not produce much in terms of toxicity since it is not designed to be used for an extended period. It should only come into contact with food for a short amount of time and then be disposed of accordingly.
Cured epoxy is studied as food safe, having no free solvents and presenting low toxicity. It has been found to be well tolerated even at very high doses.
However, epoxy resins that have not been cured or incomplete curing process may contain residual solvents that can vary from being released into the food.
Every household item like kitchen countertops, cutting boards, serving plates, and others that comes in direct contact with food items is able to filtrate harmful substances if not cured. But it can be made last longer when coated with food safe epoxy coating. You might also like to check experts reviews on countertop paint kits.

What Does FDA Approved Epoxy Mean?
FDA Approved epoxy is essential. It means that the epoxy resin has been tested by FDA and independently proven to be safe for food contact use.
For example, if an approved epoxy coating is applied onto a cutting board, it does not contaminate food items like raw meats, vegetables with harmful chemicals, or solvents, even if the kitchen utensil is used to cut or slice those items.
The food-grade epoxy should also be resistant and not prone to damage from the cutting board itself. It has been shown that epoxy resins do not emit harmful free molecules into the water as long as the curing process is finished before coming into contact with it.
This can be attributed to the fact that epoxies are cured with substances such as amines, phenols, and other materials.
In order to be approved by the US Food and Drug Administration (FDA), a polyurethane epoxy resin product must fulfill the Title 21 Code of Federal Regulations: CFR 175 provisions 105, 300, and 400, as well as numerous other checks.
The requirements are as follows: The material should not impart any flavor or odor to the dish. Only small amounts of non-crosslinked components are acceptable.
Contact with the product can’t alter the food’s composition. There is no danger of harm to human health as a result of the consumption of the substance.
What Ingredients Should You Watch Out For?
Bisphenol A (BPA) is one ingredient consumers should be mindful of. “BPA” is a chemical compound used in epoxy resin production, but there are different grades of BPA used to create different strengths and quality levels.
Since it has been found to have hormone-altering properties linked to cancer, this component may pose additional risks when processed or stored with food. Users should research the components of a particular epoxy resin before use.
However, further study is necessary. If you want to reduce your risk of injury, search for “BPA-free” markings and numbers at the bottom of containers, which indicate that they are free of bisphenol A (BPA).

What Is BPA?
Bisphenol-A (BPA) is an industrial chemical used primarily in the production of polycarbonate plastics and epoxy resins. It has been used for over 50 years to make plastic products such as water bottles, sports equipment, medical devices, eyeglass lenses, CDs, and DVDs.
The Food and Drug Administration (FDA) is responsible for ensuring that food and medical products remain safe and effective.
FDA scientists review data from years of research before determining whether a substance may be used as an indirect food additive or must receive premarket approval as a drug.
Over the past several years, studies have raised concerns about the possible effects of bisphenol-A and other chemicals that are part of the bisphenol group.
BPA is an ingredient in the epoxy resin coating used on the interior surfaces of some food and beverage cans. It is also used to line some metal products such as iron and steel water containers, tin cans, bottle tops, jar lids, and tube wiring.
Even at low levels, BPA is deemed safe by the FDA. While the FDA continues to study BPA, it has yet to make a decision on whether or not it will ban the chemical.
Before choosing epoxy resin, be sure to read the following precautions regarding BPA.
Epichlorohydrin
Epichlorohydrin is an organic compound with the formula Cl3CH2OH. It is a colorless liquid with a pungent ether-like odor. Epichlorohydrin is used as a monomer in the production of epoxy resins.
It is also used as a pesticide and as a stabilizer for latex paints. In addition, epichlorohydrin is a precursor to several pharmaceutical drugs.
Epichlorohydrin has been shown to be toxic and possibly carcinogenic in humans. Inhalation of high levels can result in irritation or coronary spasms, while higher doses may lead to unconsciousness and death from respiratory paralysis.
The mechanism for this toxicity is generally thought to be due to the fact that epichlorohydrin can readily form glycerol side chains in proteins. This modification would then lead to the disturbance of normal function.

Carbolic Acid
Carbolic acid, phenol, or the carbolic smoke ball was an antiseptic and disinfectant. It was used to clean wounds and as a general disinfectant before the introduction of antibiotics.
It is no longer used because it is toxic and can cause severe burns. It is used in agriculture, particularly in wood preservation and pest control.
It is also found in many household disinfectants, studied as a possible antibacterial agent, and in smoke balls used for fire safety.
Carbolic acid should only be handled by health professionals wearing protective equipment due to its corrosive effects on human tissue.
Get Food Safe Epoxy With Bisphenol A (BPA)
Even though epoxy resins have been manufactured for over 50 years, the FDA has not given a verdict on whether they are considered safe.
If you wish to avoid any possible injuries from epoxy resin, be sure to research the product before use. In addition to checking for BPA-free numbers on containers, look for food safe epoxy that does not contain bisphenol-A.
Not To Be Used For Storage Of Food
Epoxy resins are not typically recommended for use with storing food or beverages because of their possibility to leach into the product.
This may be harmful due to the presence of bisphenol A which could create dangerous exposure for consumers. To avoid any possible exposure, look for epoxy materials labeled as food safe.
If you need to use epoxy resin for storage purposes, be sure that it is thoroughly cured. This may take up to four weeks at room temperature or one week when curing in the refrigerator.
Working With Cured Epoxy Resins
Once the epoxy resin has been cured, it is safe to be around. However, it should not come in contact with any products as this may cause harmful chemical reactions.
It is also important to wear gloves when handling the product for its adhesive properties and toxicity levels. If you do get epoxy resin on your skin or clothing, make sure to use soap and water to clean it off.
Keep The Epoxy And Food Apart
As mentioned earlier, the epoxy resin may come in contact with food if not stored properly. When using containers for the storage of food, make sure that the container is specifically labeled as safe for cooking or microwaving.
If you are looking to use epoxy resin to line a metal container for cooking food, be aware that it can react negatively with certain foods. This is because epoxy resin may corrode the container, which can lead to harmful chemicals being released into your food.

Accuracy Mixture Has To Measured & Mixed With Ratio (1:1)
Maintaining the correct ratio is essential for making a successful epoxy product. Because of its low viscosity, epoxy resin has to be mixed equally with both components in order to make the mixture stick properly.
One of the most common ratios used when mixing two-part epoxy resin is a one-to-one ratio by weight. This means that equal weights of each component are needed to make one complete mixture.
Be sure that both components are thoroughly mixed before applying the epoxy resin to any surfaces. If you are using a product like epoxy paint, be sure to follow manufacturer directions. The ratio may vary depending on the type of coating desired.
Follow The Instructions For Curing & Maintaining
After your epoxy resin has been applied to any surface, it is important to follow manufacturer instructions on curing and maintaining the area properly.
Epoxy resins typically need at least 24 hours of curing time before they can be used for their final purpose. If you are using epoxy paint or coating, this may take up to 48 hours before it can be used on food surfaces.
Be sure to read all warning labels on the epoxy resin container before use. Some epoxy products may include radiator fluid or diesel fuel which can create dangerous fumes when applied incorrectly.
You should also follow safety instructions for using an epoxy paint product, including wearing gloves and eye protection while applying.
How Do I Know How Harmless My Epoxy Resin Is?
Epoxy resin is a commercial product that can be purchased from multiple stores and online retailers. Because of the commercial nature of the epoxy resin, it is often regulated as a food additive as opposed to paint or coating.
In this case, you should always check if epoxy resin contains bisphenol-A. This chemical may have been included during the manufacturing process.
This chemical, if present in large doses, can be harmful to people due to its toxicity levels. To find out, you can contact the manufacturer directly.
The manufacturer will be able to let you know, or you can check the product’s official website. There, you’ll learn which chemicals are used in a given casting resin’s manufacture. The warning label for hazardous products is equally useful.
How To Choose & Use Food Grade Epoxy Products?
There are a number of epoxy products available for use in the kitchen. Some may be used to coat food preparation surfaces, while others may line containers before cooking.
Your choice of epoxy product will depend on what you need to use it for and how much money you want to spend. It is also important that whatever surface or container you plan to use the epoxy on is properly cleaned and dried before applying.
Food preparation areas should be washed with soapy water after you are finished preparing food to remove any residual debris.
To help you out below, we have compiled three factors you should consider when choosing & using an epoxy product.
