Ameron’s Amercoat® line offers a wide variety of epoxy, alkyd and polyurethane coatings. Its PSX® product line is made of several engineered siloxane coatings, which are available in a variety of colors.

Amerlock® 400

Amerlock® 400 is a low VOC epoxy that can be used direct-to-metal and is available in many colors. It can be applied to tightly adhering rust and old paint and provide a high degree of chemical and corrosion resistance. Perfect for complex plant and offshore corrosion problems.


Amershield® is polyurethane top coat that can be applied direct-to-metal or concrete in protected environments. For added protection, we recommend combining with Amerlock®. This coating provides outstanding weather resistance as well as chemical and stain resistance.
