RAL1006 maize yellow pure powder coating paint epoxy resins solid powder coating
Because of the large number of available epoxy resins each resin’s ability to react with a wide variety of curing agents, nearly and combination of desired physical properties can be obtained. With proper selection of components (raw materials), epoxy-based (pure epoxies and hybrids) coating powders can be formulated to be FDA compliant for food contact applications. The primary limitations of epoxy-based coatings are their poor weather ability.
