Catalysts
Dibutyltin Diacetate (DBTA) | Manta CAT-DBTA
Manta CAT-DBTA is dibutyltin diacetate (CAS 1067-33-0), an organotin catalyst for silanol condensation, polyurethane crosslinking and transesterification, used in rigid polyurethane foams, RTV silicones that need fast skin-over, fast-drying industrial coatings and adhesives. Its tin content is 33.4% – 34.4%, higher than that of dibutyltin dilaurate.

Overview
Manta CAT-DBTA is a dibutyltin diacetate (DBTA/DBTDA) catalyst for applications that need rapid reaction kinetics. It accelerates transesterification, silanol condensation and polyurethane crosslinking, and suits industrial processes where short cycle times and quick green strength matter.
Its tin content is higher than that of Manta CAT-DBTDL, and it gives shorter gel and tack-free times than standard organotin catalysts. The product is sensitive to moisture, so containers must stay tightly sealed.
Dibutyltin compounds are regulated in several markets. In the EU, REACH Annex XVII entry 20 restricts them in mixtures and articles supplied to the general public above the tin limit set in that entry. CAT-DBTA is intended for industrial formulation. Check the rules for your market and end use, and refer to the Safety Data Sheet.

Frequently Asked Questions
How does Manta CAT-DBTA differ from Manta CAT-DBTDL?
Both are dibutyltin catalysts. CAT-DBTA has a tin content of 33.4% – 34.4% and is the faster of the two, while CAT-DBTDL has a tin content of 18.0%-19.2% and gives a more balanced profile. Choose by the gel time and pot life your system needs.
How should Manta CAT-DBTA be stored?
Store in a cool, dry, and well-ventilated area. Manta CAT-DBTA is sensitive to moisture; ensure containers are tightly sealed to prevent hydrolysis.
Can Manta CAT-DBTA be used in products for consumers?
Dibutyltin compounds are restricted in the EU in mixtures and articles supplied to the general public above the tin limit in REACH Annex XVII entry 20. CAT-DBTA is intended for industrial formulation. Check the rules for your market and end use.
