Hybricor™ 204 – Hybrid Corrosion Inhibitor Pigment

Hybricor™ 204 is an organic/inorganic hybrid corrosion inhibitor pigment, a proven effective replacement for Cr 6+ in aerospace primer applications on aluminum and other non-ferrous substrates. The fine particle size of Hybricor™ 204 (7 Hegman) permits it to be easily incorporated into a coating using a high speed disperser. It is effective in primers, DTM and thin film (< 20 micron) applications. It does not affect pot life of 2K systems. Use level varies by intended application requirements.
