Cotin® 280

Cotin® 280 is a liquid organotin carboxylate catalyst recommended for use in room temperature vulcanised (RTV) silicone systems and polyurethane foams and elastomers. Cotin® 280 should be considered a “moderate to rapid” catalyst, for relatively faster cure. It does not utilize acetic acid in its manufacture, and therefore, does not have the odor or corrosiveness normally associated with organotin acetates. Cotin 280 should be used at an equal active weight basis as dibutyltin diacetate.

Other Hazards
Fumes and vapors from this product may cause eye irritation. May cause abdominal cramps, nausea, and diarrhea. May cause irritation of the digestive tract. Contact with skin may cause slight irritation. May be absorbed through the skin in harmful amounts. Direct contact witih eyes may cause mild irritation with redness and swelling of the conjunctiva. Toxic effects on the immune system were observed in repeat oral dose animal studies. Prolonged or repeated skin contact may result in the organic tin being aborbed through the skin in harmful amounts.
