You may have heard of formaldehyde, a dangerous chemical that is used in everything from clothing to cosmetics. Because of its prevalence, it’s important to pay attention and make sure you’re not exposing yourself or your loved ones to this harmful substance.
But does epoxy resin contain formaldehyde? Let’s talk about what we know so far.
Formaldehyde is a gas with a distinct odor that can be found naturally in the environment as well as produced by humans. According to the Centers for Disease Control and Prevention (CDC), “formaldehyde is used mainly to produce resins used in pressed-wood products, such as particleboard, plywood, and fiberboard.” It is also commonly used as an industrial fungicide and germicide.
Epoxy resin is a synthetic polymer made up of two main ingredients: epichlorohydrin (ECH) and bisphenol A (BPA).
ECH comes from petroleum products such as crude oil or natural gas; BPA comes from coal tar pitch which contains benzene rings like those founds in benzoyl peroxide (BPO).
How toxic is epoxy resin?
For the most part, epoxy resin is only dangerous when it’s in its liquid form. When you first mix the two parts for pouring (the resin and curing agent), you should use a respirator and gloves.
Vapors from epoxy resin can cause skin irritation and eye damage, so be sure to protect yourself by using all of the necessary safety gear.
When it comes to the curing process—which usually takes 24-48 hours—you don’t have much to worry about unless you are doing a lot of sanding or cutting.
In that case, wear a mask and work in a well-ventilated area with your windows open.
Unfortunately, the smell produced when epoxy resin is released into the air is pretty noxious. Although there is no danger of it harming your health after it cures (after about 48 hours), keep this smell in mind if your project will take time, as breathing these fumes can cause headaches and nausea over time.
What are the ingredients of epoxy resin?
Epoxy resins are made up of two parts: a resin and a hardener. The resin is almost always either bisphenol A (BPA) or bisphenol F (BPF).
The hardener is epichlorohydrin (ECH). Below are explanations of both ingredients, their potential health effects, and information about how they’re regulated by the government.
Is epoxy resin toxic after curing?
This is an important question—and one that we have already addressed in a previous post. In short: no, epoxy resin is not toxic after curing.
There are however different types of resin and this is key to understanding why some resins are safer than others.
What is the safest resin to use?
- If you’re looking for the product with the lowest VOC (volatile organic compounds), polyurethane is your best bet: it has almost zero.
- Polyester resin is not far behind and will emit lower levels of fumes than epoxy.
- Epoxy emits the most fumes, which are usually more harmful than those given off by polyester or polyurethane
Can epoxy resin make you sick?
If you’re a fan of arts and crafts, you may have noticed that epoxy resin is increasingly popular. If you’re unfamiliar with this material, think of it as something similar to glue, but that hardens in its container.
It can be used for a variety of things like jewelry making, resin-topped tables, and just about anything else you can dream up.
It is used by people around the world because it is incredibly versatile and easy to use on your own at home. However, many people aren’t aware that the epoxy resin does contain some dangerous materials that could make them sick if they are exposed during application or over time.
This article will take a look at some of the dangers associated with epoxy resin so that you can decide if it’s right for you!
Is epoxy cancerous?
No, epoxy does not contain formaldehyde.
Some people worry about the toxicity of epoxy resin.
This is why it’s important to always read labels and safety information that come with any product you use.
Is resin poisonous to humans?
Epoxy resin is not poisonous to humans, but there are a few things you should keep in mind when working with epoxy.
First, when people talk about material being poisonous, they generally are referring to the ability of that material to cause harm or death if the material is ingested.
In other words, the substance is poisonous if it can kill you if you eat it.
However, this definition doesn’t take into account other ways in which materials can be harmful to humans, including skin irritation and respiratory issues that could arise from exposure.
It also doesn’t consider the fact that some materials may be safe for human consumption but might not be so great for houseplants!
What is Bisphenol A epoxy resin?
Epoxy resin is a type of plastic. It’s used for containers, food and beverage cans, toilet seat covers, water pipes, and as coatings for items like paper receipts. The Food and Drug Administration has approved epoxy resins for use in food and beverages packages.
It’s also used to make epoxy resins. Epoxies are typically sold as two-part systems: the resin (or “hardener”) and a curing agent that catalyzes the reaction that creates the polymer structure of an epoxy coating or adhesive.
Epoxies are often used in paints, coatings, adhesives, fiber-reinforced composites like boat hulls or surfboards, flooring systems—the list goes on.
There are many different types of epoxies. Some can contain BPA (also called bisphenol A), which is known to cause health problems when ingested by humans at certain levels.
In fact, BPA is a building block of polycarbonate plastics (which have been found to be unsafe) and some kinds of epoxy resins too!
Epoxy is not toxic and does not contain formaldehyde. However, it does contain high amounts of VOCs (volatile organic compounds) and should be used in a well-ventilated area with the proper safety equipment.
There are two types of epoxy, one requires heat to cure it and the other requires UV light.
The first type of resin needs to be cured for 24 hours at 150 degrees Fahrenheit. The second kind can only be cured using UV light, has a lower viscosity, is odorless but contains BPA (bisphenol A).
Do not use epoxy under any circumstances if you have allergies or skin irritation. If you have asthma or lung problems do not use epoxy materials without consulting a doctor first.
