How does the color of CERAM-KOTE coatings hold up to UV degradation?
CERAM-KOTE epoxy coatings use modified epoxy resin as the binder for the ceramic powders. CERAM-KOTE 54®, CERAM-KOTE 54N, and CERAM-KOTE 99 actually have good UV stability when compared to other epoxies, but they are still epoxies. CERAM-KOTE 2000 and CERAM-KOTE 60 do not have good color fastness in UV light. Epoxies are not known for their resistance to UV (Ultraviolet) light. Due to the molecular structure of epoxies, the UV light breaks down the molecular structure and causes “chalking” on the surface. This does not affect the performance of the coating in preventing corrosion for many years. Most CERAM-KOTE epoxy coatings will maintain their color and appearance for six months to a year depending on the exposure to UV*. (Colorfastness for bright reds, oranges and blues changes within three months). If color fastness is required, Freecom recommends using CERAM-THANE 200. * CERAM-KOTE 60 must be topcoated for UV protection.
