Two-component, high-build, multipurpose polyamide cured epoxy coating

When it comes to all-around industrial protection, PPG AMERLOCK 600 is the one epoxy you can't do without.

PPG AMERLOCK 600 is a high solids, high build, fast drying, two-component polyamide epoxy designed to protect steel, concrete, and other exposed substrates in industrial, marine, petrochemical, fabrication, energy, water treatment and mining environments.

In refineries, chemical plants and just about anywhere else equipment and structures take a beating, PPG AMERLOCK 600 has the answer. Its high solids content ensures adequate protection of sharp edges, corners, and welds. It can be applied directly to marginally prepared steel surfaces. And with low VOC (240g/L), fast dry times, and durability, this versatile epoxy is a must-have for any environment.
