Analysis of the impact points of polyester epoxy coatings

polyester epoxy powder coating is the most important and optimal performance of powder coating products in China, epoxy resin and polyester epoxy resin for its performance has the greatest impact and has been studied in depth, so people turn to research and improve the design of facial fillersThe research shows that the pigment variety has a great influence on the performance of polyester epoxy powder coating, and the design of pigment variety is indispensable to improve its performancein order to compare the effects of different pigment varieties on polyester epoxy powder coating and coating performance, the researchers tested another group of titanium white, medium chromium yellow, iron-green, iron-red, iron-yellow, sun-resistant yellow G, enamel green, indigo blue BGS, big red BBN, bright red, Yonggu red F3 AND Yonggu red F5RKThe results show that various pigments have different effects on the reaction activity of polyester epoxy powder coatings, and the difference severity and dispersion of pigments affect the melting level fluidity of powder coatings and the leveling, gloss and impact resistance of coating filmstherefore, the effect of pigments on powder coating and film performance should be fully considered in the design of powder coatingsIn addition, carbon black is also commonly used black pigmentThe selection of high wear-resistant carbon black, Japanese MA-100 carbon black, high-pigment carbon black, German XPB-90 carbon black, etcfor testing, also shows that different varieties of carbon black on polyester epoxy powder coating glue time, melting level fluidity has no obvious impact on the appearance of the coating, gloss and impact resistance, but has a significant impact on color difference
