Epoxy Difference

The Naturalis Epoxy Resin Difference

When compared to traditional plastic polymers epoxy offers excellent moisture, chemical, impact resistance, No VOCs, and a comparatively long shelf life, all making it a great choice for art applications.

What is Epoxy?


Epoxy is a resin that polymerizes like a plastic. The liquid resin is mixed with a hardener to trigger the hardening process. Our Resin and Hardener are used in a simple 1:1 ratio to achieve a fully cured end product. The working time for the mixed resin and hardener is approximately 40 minutes, and fully “cures” and sets completely hard in 24-72 hours based on the temperature or humidity of the room.

All epoxy resins will begin to yellow over time. Naturalis utilizes the next generation of resins, along with protective materials such as HALS, and UV Absorbers (typically found in SPF sunscreen) to help resist yellowing. All our products are packaged in light blocking color-coded bottles.

* Test Parameters:
Identical works of art, with our Arte The Frog TM images, were protected with an epoxy coating. Our Naturalis Paint ARTIST GRADE, GALLERY GRADE and two other market leading suppliers products were chosen. Industrial and Specialty chemical products alike are tested with what is called accelerated weather in a QUV machine. That scientific device controls the temperature, UV exposure and other properties such as moisture. In identical tests, representing 6-12 months we are very excited with the results. Our ARTIST GRADE material matches or slightly exceeds the chosen competitors, and our GALLERY GRADE performs best in class.

How We Protect Our Products

Two shields for optimum UV protection

1

We protect our material with helpful UV protective additives. Epoxy resin products will typically yellow over time. There are some great measures we can use to resist this. In our case the first step we take is to choose a specialty epoxy resin type. It is more expensive, but inherently helps to resist the yellowing effects of UV.

The second key measure is protective additives. HALS do an excellent job. Another approach is to use UV protective additives, very similar to the products in a sunscreen that gives an SPF type value.

The images to the side is a look inside the stainless steel production tank. The resin and the hardener are totally clear. To give some indication of scale and depth this tank is about the size of a small car, and the resin and hardener products are crystal clear. Ironically the SPF additives are a yellow, straw like liquid. Equally ironically it dries and sets clear, but is a yellow hue that we add and looks slightly yellow until it dries. The other protective measure we take is to use colored bottles. That bottle also protects the product from UV rays. The hardener is something called an amine, and that will yellow over time, especially if it is exposed to UV light, thats why we put that in a black (protective) bottle. The bottle choice, and lid choice also helps to avoid mixing up the lids. White bottle - White lid, and, Black bottle - Black lid. It is possible to “glue” the lid on if that gets accidentally mixed up.
