Q1: What is the primary function of Borchi DBTDL in polyurethane systems?
A: Borchi DBTDL is a highly active tin-based catalyst that accelerates the reaction between isocyanates and hydroxyl groups, enabling efficient gelation and curing in polyurethane foams, coatings, adhesives, and sealants.
Q2: How should Borchi DBTDL be handled and stored to maintain stability?
A: Store in tightly sealed original containers under dry, cool conditions away from moisture, strong oxidizing agents, and direct sunlight. Avoid prolonged exposure to ambient humidity or elevated temperatures, as this may affect catalytic performance over time.
Q3: Is Borchi DBTDL compatible with other common urethane catalysts?
A: Yes — it is frequently used in combination with amine catalysts (e.g., DABCO, TEDA) to balance reactivity, foam rise, and cure profile. Compatibility should always be verified in the target formulation due to potential synergistic or inhibitory effects.
Q4: What are typical dosage guidelines for Borchi DBTDL in PU formulations?
A: Dosage depends on formulation requirements and desired processing window, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight relative to the polyol component. Optimization through small-scale trials is recommended.
