Durapol is Protech’s alternative to nylon powder coatings, designed to meet the most demanding performance requirements. These powders are engineered using thermoplastic co-polymer technology and are formulated to furnish remarkable hardness properties. Durapol powders are a high end application solution providing huge economic benefits compared to nylon based products.

The salt spray resistance of all properly applied Durapol co-polymer powder coatings is excellent. A zinc or iron phosphate substrate, sandblasted and coated with the above product, will provide a durable finish showing no effect in 2,000 hours of salt spray exposure.
The specific chemistry of this co-polymer requires an annealing process after cool down from post heat in order to derive the ultimate hardness and physical properties. This process will occur at ambient conditions in approximately sixty days but can be accelerated as indicated below:
