PPG SigmaCover 2 (formerly 640LT Low Temperature and Amerlock 2C) is a fast drying, high solids, two component epoxy coating, which offers excellent adhesion to cement and steel, and can be applied at temperatures as low as 0C. London Underground Approved LUL Cert 1329.

PPG SigmaCover 2 is designed for use on bridges, tank exteriors, containers, oil tanks and bunds. It is recommended for use in commercial, construction and industrial environments to protect the surfaces of concrete and steel from chemical spillages, as well as splashes and fumes from acids, alkalis, solvents and water.

PPG SigmaCover 2 is self-priming and results in a semi-gloss finish. It is available in most BS and RAL colours and can be overcoated with a wide range of topcoats.
