Application Use
WANALINK ® 6200 It is a light yellowish brown to dark amber liquid at room temperature.
WANALINK ® 6200 is 4,4'- Bis ( sec-Butylamino )- Diphenylmethane, trade name, is a liquid secondary diamine. Because the hydrogen atom on each amino group is replaced by a sec-butyl group, the combination of active hydrogen atoms and sec-butyl groups in a limited space produces many unique properties. The amino part forms a urea bond that affects the hard segment, while the butyl group acts as an internal plasticizer. It is connected to the polymer matrix and will neither leach out nor precipitate. At the same time, the alkyl group increases the solubility of the diamine, making it miscible with almost any polyol and polyamine. WANALINK® 6200 Can be used in rigid foams, flexible foams, coatings, adhesives, sealants, and elastomers. Typical usage is 1-5% of the polyol. It can also be used in sprayed polyurea and various compounds used for metal and concrete repair.
