Socomore PRIAM-CE111A (780-Gram-Can)

PRIAM CE 111 2K Epoxy Primer

Overview

PRIAM CE 111 is a zinc chromate-free two-component epoxy primer developed for aerospace radomes, engine components, and erosion-sensitive composite structures. Designed to protect aircraft parts, wind turbine blades, and leading-edge surfaces from water, sand, and hail erosion, it provides excellent adhesion, fluid resistance, and environmental durability. When used with PRIAM 32005 White Topcoat, it forms a high-performance protective coating system approved by major aerospace OEMs and maintenance organizations.
