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
APPLICATIONS
• Concrete primers (100-500 g/m2)
• Pigmented concrete coatings (100-500 g/m2)
SHELF LIFE
At least 12 months from the date of manufacture in the original sealed container at ambient temperature.
STORAGE AND HANDLING
Refer to the Material Safety DataSheet for Anquamine 728 curing agent.
