MILCOAT®
PU Land Systems Semi-Gloss 50
MILCOAT® PU Land Systems Semi-Gloss 50 is a two-component, solvent-based, UV-stabilized 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 semi-gloss finish with excellent resistance to weathering and mechanical action.
The high-crosslinking polyurethane formulation combines flexibility, colour fade resistance and good anti-sag properties with a uniform appearance and low dirt retention, making it suitable for vehicles, equipment and other exterior surfaces exposed to demanding service conditions.

Intended Uses
MILCOAT® PU Land Systems Semi-Gloss 50 is designed as a durable exterior finish coat for military land systems, transport equipment and associated industrial equipment where a semi-gloss polyurethane finish is required.
It is intended for application over compatible epoxy or polyurethane primers, forming the final protective and decorative layer of the coating system. Its combination of exterior weathering resistance, flexibility, mechanical durability and colour retention makes it particularly suited to equipment that operates outdoors and is exposed to demanding service conditions.
