RAL1005 honey yellow Polyurethane powder coating for Pipeline corrosion
Polyesters are typically somewhat softer and less abrasion resistant than their polyurethane counterparts. The additional crosslinker inherent in a polyurethane powder formulation is responsible for the added performance. Using the somewhat archaic pencil hardness test, polyesters clock in at H hardness whereas polyurethanes can achieve H to 5H depending upon the specific formulation. The higher hardness products typically sacrifice mechanical flexibility.
DESCRIPTION
1 “Polyurethane powder coating” is a series of polyurethane based powder coating formulated for exterior environment.
2 Offering excellent anti-corrosion and flexibility properties.
3 Excellent smoothness and high gloss
4 Available for a wide range of colors and gloss levels to suit different applications.
