Polyurethane Powder
Coatings
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.
