powder coating gloss stable

Light stabilizer is a kind of material which can improve the stability of molecular material. It can prevent the aging of the polymer material and increase their service life.

Light stabilizer can reduce light degradation, improve the light fastness of polymers and composites material, because the majority of light stabilizers are absorb ultraviolet light, so it is also customary to this class of substances often called ultraviolet absorbent. Light stabilizers are very significant for preventing the aging of composite materials and prolonging their service life, and the amount is very small, generally only 0.01% to 0.5% of the polymer mass.so powder coating gloss will be stable.
