Why is epoxy powder coating easy to keep?

Many countries in the world have issued regulations to limit VOC emission, and the VOC content of epoxy floor paint has been stipulated. The development of solvent-free and waterborne coatings in line with the environmental requirements has been the trend, epoxy resin has been modified to meet the needs of modern development. There are many modification ways of epoxy resin, such as nano toughening. The advent of nano - particles is of great significance for developing nano - epoxy powder coatings.

Solvent-free anticorrosive paint epoxy self-levelling paint is solvent-free, non-toxic, cost-effective, strong adhesion, corrosion resistance, impact resistance, dustproof and other characteristics, and has good physical and mechanical properties and chemical resistance.

In addition to the advantages of general powder coating, epoxy resin powder coating has the advantages of no by-product formation during curing, smooth appearance of coating film, good adhesion with metal substrate, scratch resistance, excellent electrical insulation performance, powder coating itself is easy to keep and so on.

The nanoparticle has a very high specific surface area, and its surface atoms are highly unsaturated. After forming a force with the polar group of the epoxy resin far beyond the van der Waals force, it forms a very ideal interface, with unique toughening effect, and does not reduce the band temperature. Flame retardants. The flame-retardant substances are mainly N, P, As, Sb and Bi of group V in the periodic table, and Sr, I, Al, Mg, Ca, Zr, Sn, Mo and other elements of group V. Commonly used are N, P, Cl, Br, B, Mg, and A1. Compounds of these elements can be used as flame retardants.
