Q1: What is TMG 160 Catalyst primarily used for?
A: TMG 160 Catalyst is a tertiary amine-based catalyst specifically formulated to promote the gelling and curing reactions in polyurethane systems, particularly in rigid and semi-rigid foam applications where balanced reactivity and flow control are required.
Q2: How does TMG 160 differ from other amine catalysts like DABCO or BDMAEE?
A: TMG 160 offers a distinct balance of delayed initial reactivity and strong gel-promoting activity, resulting in improved cream time and finer cell structure compared to highly reactive catalysts. Its molecular design provides enhanced compatibility with common polyol blends and reduced volatility-related handling concerns.
Q3: Is TMG 160 suitable for low-emission or low-VOC formulations?
A: Yes — TMG 160 is designed with low volatility and minimal residual odor, making it well-suited for formulations targeting reduced emissions. It contributes to lower post-cure VOC profiles without compromising catalytic efficiency in standard processing conditions.
Q4: What is the typical dosage range for TMG 160 in polyurethane foam systems?
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 total polyol component — and is often blended with other catalysts to fine-tune rise and cure profiles.
Q5: Can TMG 160 be used in moisture-cure or one-component PU sealants?
A: While TMG 160 is primarily optimized for two-component rigid foam systems, it may be evaluated in certain one-component moisture-cure formulations where controlled gelation and extended shelf life are beneficial — however, compatibility and performance must be verified experimentally under end-use conditions.
