product information
 Coscat® 83 is an organobismuth compound catalyst specially developed for two-component polyurethane systems. Widely recommended for elastomer systems to reduce catalyst toxicity. Coscat® 83 catalyst effectively reduces the toxicity and effectively replaces lead, mercury and other organometallic carboxylates and organotin catalysts without reducing performance. 

Coscat® 83 catalyst can promote fast curing of the system, however, in the final stage of curing of medium soft to medium hardness system will slow down the curing speed and cause surface stickiness, while Coscat® Z-22 can effectively reduce the surface caused by slow reaction speed. stickiness problem, so as to achieve a good final curing effect. We recommend a 1:1 weight ratio of Coscat® Z-22 to Coscat® 83 catalyst.
