Flame retardant for powder coatings
Flame retardant thermosetting powder coatings are mainly made by adding 1-10% of the total amount of flame retardant to conventional cyclopolymer powder coatings or polyester powder coatings, taking the flakes extruded from the extruder for direct combustion to determine the oxygen index, and evaluating it with reference to GB 2406-1993. And refer to GB 14907-2002 to determine the fire resistance. The conditions that flame retardants should have: High flame retardant efficiency, no or slightly lowering the original physical, mechanical andRead More …
