What is PolyKoat?

Design Analysis Inc., merged their innovative metal adhesion technology with unique polymer combinations to produce decorative and protective coatings for a wide

variety of sheet metals.

A Superior Product

PolyKoat is:• highly resistant to abrasion, UV & weather • extremely resistant to typical chemicals• formable into Zero-T bends & unique shapes• produced using ½ the energy• environmentally friendly, containing no VOCs or BPA • costs less to produce than painted coils

PolyKoat’s patented process produces a superior alternative to paint and epoxy coatings

PolyKoat vs painted coatings: • No VOCs produced• No BPA in the formulations• Inert raw materials used• No cleaning section required• No caustic chemicals needed• Simple, energy efficient process• Energy Star ratings a potential

PolyKoat is more environmentally friendly than traditional paint & coating systems

An Environmentally Friendly Process
