ALIPHATIC AMINES AND THEIR ADDUCTS Aliphatic amines are low in viscosity and are preferred curing agents at ambient conditions for general applications. They offer excellent combinations of properties and are used in adhesives, coatings, composites and construction applications. Atul offers several grades of aliphatic amine curing agents with varying viscosities, reactivity and performance properties after optimum curing.
