Socomore PRIAM-32005 PARTIE B (200-Gram-Can)

PRIAM 32005 MT – 2K Polyurethane Anti-Erosion Topcoat

Overview

PRIAM 32005 MT is a two-component polyurethane anti-erosion topcoat designed for high-performance aerospace applications. It is primarily used on aircraft radomes and engine components such as cones, blades, and outlet guide vanes (OGVs). The coating provides strong resistance to erosion, chipping, and environmental exposure while maintaining compatibility with electromagnetic transparency requirements for radome applications.
