PPG SigmaCover 280
PPG SigmaCover 280 is a two component, polyamide cured, epoxy primer that can be used as a general purpose epoxy primer, ideal for use on steel and non ferrous metals. Replaces Amercoat 185 HS.
Best Uses
SigmaCover 280 (Amercoat 185 HS) works excellently well at providing good adhesion to steel, galvanised steel and non ferrous metals ready to be overcoated with most alkyd, chlorinated rubber, vinyl, epoxy and two component polyurethane coatings. Because of its excellent adhesion 280 has fantastic recoating properties that provide surfaces with the perfect protection.
