Features Of TMG 319 Polyurethane Catalyst

  1. Highly selective tertiary amine catalyst optimized for polyol-isocyanate reaction kinetics.

  2. Low volatility and minimal odor, supporting safer handling and improved workplace air quality.

  3. Excellent compatibility with common polyether and polyester polyols across flexible and rigid PU systems.

  4. Enables balanced reactivity—promoting gelling without excessive blowing—ideal for dimensionally stable foams.

  5. Stable in storage at ambient conditions; non-corrosive to standard processing equipment.

Typical Applications Of TMG 319 Polyurethane Catalyst

  1. Flexible slabstock foam for mattresses and furniture upholstery.

  2. Rigid polyurethane insulation foams in appliance and construction panels.

  3. Integral skin and microcellular foams for automotive interior parts.

  4. Coating and adhesive formulations requiring controlled pot life and rapid cure development.

  5. Water-blown low-emission foam systems compliant with indoor air quality standards.
