PermaLiner™
Polyurea Hybrid Spray Coating
PermaLiner offers outstanding performance and durability when used as a protective coating in the automotive industries. PermaLiner displays quick cure times and offers industrial grade adhesion.
PermaLiner is a two-component, 100% solids, zero-VOC, UV-stabilized modified polyurea-polyurethane blend. Because it is not pure urethane, PermaLiner is far less sensitive to moisture, significantly reducing the risk of bubbling in high-humidity climates. PermaLiner displays excellent UV characteristics and is suitable for interior or exterior use.
