¹Ì»¯¼ÁµÄÓ¢ÎÄÃû³ÆÊÇcuring agent, Definition: Substances or mixtures of substances added to a polymer composition to promote or control the curing reaction. An agent which does not enter into the reaction is known as a catalytic hardener or catalyst. A reactive curing agent or hardener is generally used in much greater amounts than a catalyst, and actually enters into the reaction. Cross-linking agents are distinguished from catalysts because they react with molecules and are coupled directly into the cured system as a structural member of the polymer.
