Polyurethane Powder Coating

Polyurethane Powder Coating

Polyurethane powder coating is recommended for use in exterior situations when lower film builds with superior flow are particularly important. Specialised versions are available where high surface hardness is required, e.g. anti-vandal coatings, stain resistant coatings. This type of coating is popular with petrochemical companies.
