Duralloy is Protech’s line of PVC grade thermoplastic powder coatings which do not require a primer. These powders offer the same high performance characteristics as our industry leading PVC fluidized bed coatings while delivering significant cost benefits by eliminating the need for a primer. Duralloy is available in selected colors.
The salt spray resistance of all properly applied Duralloy PVC powder coatings is excellent. A zinc or iron phosphated substrate, sandblasted and coated with the above product, will provide a durable finish showing no effect in 4,000 hours of salt spray exposure and less than 1/8” undercutting will be observed on a scored panel exposed to 2,000 hours.
