Question 1

What is the difference between epoxy and resin?

Accepted Answer

Epoxy and resin are related but not identical. Resin refers to a broad category of viscous substances that harden into solid polymers. Epoxy is a two-part system consisting of resin and a hardener that undergoes a chemical reaction when mixed to cure and form a stronger, more durable material. All epoxy is resin, but not all resin is epoxy. Epoxy requires a hardener to cure, while some resins use catalysts or UV light.

Question 2

Does epoxy dry hard?

Accepted Answer

Epoxy dries, or cures, into a hard and rigid material that forms a strong and durable bond. Once dry, it creates an impact resistant surface comparable to tough plastics with a solid barrier against moisture and many chemicals. However, even though it is strong, epoxy is not very flexible and can crack if the substrate moves.

Question 3

Can epoxy be removed?

Accepted Answer

Yes, epoxy can be removed, but it can be difficult because it forms a very strong bond. The removal method depends on the surface and the extent of the epoxy. The best way to remove epoxy is with an angle grinder or sander, heavy-duty scraper, or heat gun. You can also use a methylene chloride-based paint stripper or specialized epoxy remover to break down cured epoxy. However, always follow the manufacturer's instructions for chemical removal.

Question 4

How does the form of paper epoxy affect its application and performance?

Accepted Answer

Different forms of paper epoxy apply and perform in different ways. For example, you can pour or brush liquid epoxy to create a smooth, glossy, durable surface, while you can shape putty to fill gaps and make repairs. Adhesives apply like glue for high bonding strength, while coatings roll or spray onto surfaces to create a protective layer. While the form of paper epoxy affects handling, the fundamental strength and bonding still come from the chemistry itself. We've got paper epoxy in all types of forms, including gel or liquid.

Question 5

Which usage locations are suitable for paper epoxy?

Accepted Answer

Epoxy adhesives are suitable for a wide range of usage locations. We stock epoxies for every usage location you may need, including landscape, general, and masonry. However, avoid locations with flexible joints or moving parts where rigid epoxy can crack, and locations with constant chemical exposure where strong acids, bases, or solvents can break down epoxy.
