PowerCat™ DBTDL

PowerCat™ DBTDL is yellow amber, oily liquid. It is insoluble in water and most common organic solvents.

PowerCat™ DBTDL catalyst is a versatile catalyst that can be used in various urethane cross-linking reactions and silanol condensation reactions. It drives the addition of alcohols with isocyanates to accelerate and complete the formation of urethanes. PowerCat™ DBTDL catalyst is stable to hydrolysis but will hydrolyze in the presence of aqueous caustic at room temperature. PowerCat™ DBTDL catalyst is incorporated into the final product and does not require removal. It is a silicone fluid catalyst for ease of processing.
