MILCOAT®
PU Land Systems Matt 03
MILCOAT® PU Land Systems 03 Matt is a two-component, solvent-borne aliphatic polyurethane acrylic topcoat developed for military land systems and other demanding exterior applications. Designed to comply with RSA-MIL-SPEC 42 – Issue 5:2005, it provides a durable matt finish with excellent UV resistance, colour retention and mechanical performance under harsh operational conditions.
The formulation incorporates UV absorbers and hindered amine light stabilisers (HALS) to improve long-term weathering and colour stability. Low infrared reflectance supports camouflage requirements, while the fully cured coating provides excellent resistance to chemicals and solvents.
Pack Sizes: 5L & 20L Kits.
