Amercoat 240
Universal Epoxy Coating

Amercoat 240 is a surface-tolerant, direct-to-metal universal epoxy.
It provides a much superior high-film build (up to 12 mils in single coat) and optimal corrosion protection in immersion, non-potable and corrosive chemical environments.
Best for use with immersion surfaces as well as for exterior protection, it can be applied down to 40°F and cures down at 32°F.
It offers excellent edge coverage (75% compared to the typical 25% with other coatings), meaning less strip coating is required.
