WANALINK® 6200 is the brand name of 4,4’-bis(sec-butylamino) Diphenylmethane. It is a liquid secondary diamine. One of the atoms of hydrogen on each of the amine group is substituted by a secondary butyl group, so that the combination of an active hydrogen atom and a secondary butyl group in a confined space creates many unusual properties. The amine portion forms area linkages which affect the hard segment domains, while the butyl groups functions as inner plasticizer. Bonded to the polymer matrix, it neither leaches, nor bloom. The alkyl groups also improve the solubility of the diamine, allowing it to blend readily with almost any polyol or polyamine. view less

Wannate® HDI is a liquid aliphatic diisocyanate. It is a colorless or pale yellow liquid with low viscosity. Wannate® HDI is a raw material for polyurethanes. Products based on Wannate® HDI are mainly used in PU varnish, top-grade coatings, car refinishing paint, plastic coating, top-grade wood-paint, industrial coating, anti-corrosive coating, elastomers, adhesives and textile finshing agent. Polyurethane coatings based on Wannate® HDI have a high degree of oil resistance coupled with good wear-resisting; It is also lightfast and has the property of powdering resistance,color retention and weathering resistance.
In addition, Wannate® HDI also can be used in coating curing agent, high polymer adhesive, low temperature adhesive for printing paste, collar copolymer coating, and immobilized enzyme adhesive. view less
