Cata-Chek 820

Dibutyltin dicarboxylate stabilizer and PU catalyst


Cata-Chek® 820, a dibutyltin dicarboxylate, is recommended as a heat stabilizer in flexible vinyl formulations requiring a high degree of clarity. It is non-sulfur staining, furnishes good lubrication, is readily soluble in most common plasticizers, and provides minimum water blushing. Cata-Chek® 820 can also be useful in the stabilization of chlorinated paraffins and other chlorinated organic materials. Cata-Chek® 820 is recommended as a polyurethane catalyst.
