Prism Powder Coatings U-Series Polyurethane powders are designed for a range of both decorative and functional use on products for exterior exposure. The polyurethane powders have good chemical and mechanical properties. They can be manufactured in a wide range of colors, textures and glosses.

U-Series Polyurethane powders perform well over cold rolled steel, hot rolled steel and aluminum substrates suitably pretreated.

It is possible to achieve film builds of 1 - 1.5 mils, but 2 - 3 mils is the norm. Polyurethane powders are known for their smooth appearance.

As always, we recommend you consult your Prism Powder Coatings representative and perform your own physical testing to determine the suitability of a product for your requirements. See the health, safety and storage guide for further information.
