Paint Polyurethane Aliphatic Exterior Matt Fire Retardant Coatings for Blast Protection

Infrared detection is employed by armies for detection of hostility in low light and pitch dark scenarios. It is also useful to detect camouflaged presence of hostile forces. However, application of IRR resistant coatings completely negates the possibility of any kind of detection when exposed to IR light or beam. Excellent coating for land based combat equipment and plateforms.

Aether IRR Polyurethane coating is Highly Infra Red Reflective produced by high Temperature Calcinations combined with Chemical Agent Resistant coating properties. The Pigments used in the Coating have excellent UV and Visible Opacity, are Chemically inert, Heat Resistant and is stable to Ultra Violet Light. It is Non-bleeding and Non-migratory. It has Low Heat Buildup with exceptional Durability and Contrast Ratio. The Coating is compatible with most Mil Grade Primers.
