Akcrostab™ T-5139

Dibutyltin Diacetate

Description

Akcrostab T-5139 is a dibutyltin diacetate urethane foam and coating catalyst that promotes faster gassing while delaying gelation of the foam. This allows complete filling of the mold, and also provides longer storage life than stannous catalysts. Akcrostab T-5139 has a high tin % and can also be used in PVC as a stabilizer in combination with Akcrostab T-94CS in clear rigid sheet and profile extrusion. Also, it may be used as the sole stabilizer in copolymer calendering applications. (0.50 to 2.5 phr)
