Epoxy Curing Agents and Modifiers
Anquamine 728 is a waterborne amine curing agent for use in concrete epoxy primers and topcoats that delivers fast back-in-service next day under adverse cure conditions (10˚C & 60-85% RH). The product can be used with Ancarez AR-555 solid epoxy resin dispersion to facilitate 1-day floor installation (primer/topcoat) with next day walk-on. Coatings based on Anquamine 728 can be applied upto 500 g/m2 with minimal impact on cure speed.
Category:Hardener

ADVANTAGES

• Rapid dry speed at ambient and low temperatures

• Excellent resistance to carbamation

• Excellent pigment acceptance and colour stability through potlife 

• Low colour and good yellowing resistance

• Excellent adhesion to damp concrete
