Benzoin

Benzoin is a well established and reliable degassing agent for powder coatings. During the curing of a powder coating film, the benzoin melts and chemically scavenges oxygen and promotes dissolution of gases into the resin to minimize bubble formation in the coating film. Surface defects such as pinholes and other imperfections can be reduced or eliminated by incorporating 0.3 – 1.5% of benzoin into the powder coating formulation along with the other raw materials. As with anyraw material, laboratory evaluation is required for each formulation to determine the best processing method and the optimum concentration of the additive.
