Polyamine
Cycloaliphatic amine curing agents are a type of epoxy curing agent that is characterized by its cyclic structure. This structure gives cycloaliphatic amine curing agents several advantages over other types of curing agents, including:
Improved chemical and moisture resistance: Cycloaliphatic amine cured epoxies have excellent chemical and moisture resistance, making them suitable for a wide range of applications, including marine coatings, industrial flooring, and aerospace components.
Good mechanical properties: Cycloaliphatic amine cured epoxies also have good mechanical properties, including tensile strength, compressive strength, and impact resistance.
Low VOC emissions: Cycloaliphatic amine curing agents have low VOC emissions, making them a more environmentally friendly choice than some other types of curing agents.
Cycloaliphatic amine curing agents are typically used in conjunction with epoxy resins to form a cross-linked polymer network. The curing process is initiated by the reaction of the amine group on the curing agent with the epoxy group on the resin. This reaction results in the formation of a covalent bond between the two molecules, creating a strong and durable polymer network.
