Paint Polyurethane Aliphatic Exterior Eco Friendly low VOC Coatings
Growing concern for Ecofriendly coatings which are environmentally and personnel friendly has seen the industry gearing up for the need and thus the advent of Low VOC coatings.
Aether Polyurethane Coating is compliant to MIL PRF 85285,High Solids Type 1 Class H. The paint fully fulfills the requirements of the Specified maximum Limits of VOC and VOHAP contents making it an Eco-friendly Coating. The Coating is free of Cadmium, Lead and hexavalent Chromium.
This High-performance coating is excellent for platform exteriors to withstand the combat zone rigors and climatic extremes and terrains, ranging from sub-saharan to high altitude operating zones. Highly abrasion resistant it provides long lasting protection to the platform exteriors maintaining the aesthetics and longevity of the platforms hull.

Aether high durability, polyurethane topcoat is designed for use as both an internal topcoat for aircraft structural components as well as an external topcoat for military aircraft and land-based defense equipment's including platforms.
The surface should be sand blasted adhering to SA 2.5 specifications. Surface should be free of oil, grease, dust and loose particles. For mechanical cleaning surface should be sand blasted to min. ST 2 standards. Soundly prepared surfaces will lead to a better paint application. When used over old coating systems, the surface must be clean, dry and properly anchored.
