WANALINK® 6200

WANALINK® 6200 by WANHUA is a 4,4-bis(sec-butylamino) Diphenylmethane. It is a liquid secondary diamine. The amine portion forms area linkages while the butyl groups functions as inner plasticizer. Bonded to the polymer matrix, it neither leaches, nor bloom. The alkyl groups improve the solubility of the diamine and allow it to blend readily with almost any polyol or polyamine. It is compatible with a wide range of polyols, co-curing regents, and all other polyurethane chemicals. WANALINK® 6200 can be applied to elastomers. It improves flow and adhesion, lower moisture sensitivity. It is acts as a curing agent for hard and soft elastomers. Recommended dosage level is 1-5 %.
