Physical-mechanical properties of powder coating in the system “film-forming – Crosslinking agent”

The results of the influence of film-forming components o on the formation of properties of powder coating based on different crosslinking agents was showed in the work. Powder coating are one of the most promising types of paintwork materials for industrial use. Their main advantages are absence of solvents, practically waste-free coating technology (the degree of powder utilization during application is close to 100%), relative simplicity and economy during coating production. According to the results of studies it has been revealed that the use of systems “polyester film-forming– TGIC”, “polyester film-forming – НАА” provide high physical and mechanical properties of coatings without deteriorating the technological properties of the systems when using film formers with dynamic Brookfield viscosity values in the range of 3600…4200 mPa-s (at t=200 oC).
