A chromate-free, epoxy primer that meets MIL-PRF-23377 requirements and is designed to provide excellent adhesion and corrosion resistance for aerospace applications where a chromate-containing primer is not acceptable.

It is formulated for direct-topcoat applications to deliver excellent finished appearance due to minimal primer texture. Its high build characteristics allow DFT's of 50 to 100 um.

This high-solids primer is also designed to provide productive dry times and has an RTS VOC of less than 336 g/L.

Recommended Uses

Corlar® 13580S™ is recommended for use as a primer over properly treated substrates including aluminum, aluminum alloys, and steel. It is compatible with most epoxy and urethane surfacers and polyurethane topcoats
