JEFFCAT® LE-30

• Lower Polyurethane Foam Emissions – Utilizing JEFFCAT® LE-30 catalyst in a polyurethane formulation typically results in lower polyurethane foam emissions vs. conventional, non-reactive blowing amine catalysts.
• Lower Usage Level – Due to the potency of JEFFCAT® LE-30 catalyst, the usage level requirement is decreased when compared to other low emission amine blowing catalysts.
• Lower Polyurethane Foam Odor – Polyurethane foams produced with JEFFCAT® LE-30 catalyst have lower post-cure odor compared to conventional non-reactive blowing amine catalysts.
• Lower Vapor Pressure – JEFFCAT® LE-30 catalyst has a lower vapor pressure and can be used to replace high volatility, conventional non-reactive blowing amine catalysts.

Initially introduce JEFFCAT® LE-30 catalyst into the formulated B-side polyurethane resin at a 0.50 pbw usage level, for a closed cell spray rigid polyurethane formulation and 0.80 pbw for an open cell spray rigid polyurethane formulation. For 2.80 pbw water polyether flexible slabstock formulations, a starting usage level of 0.10 pbw is recommended and 0.14 pbw for 4.00 pbw water polyether flexible slabstock formulations. A 0.30 pbw is recommended for polyester flexible slabstock formulations. In an MDI based viscoelastic formulation, it is recommended to use 0.17 pbw. Adjust the catalyst usage level accordingly to meet your processing needs.

Introduce JEFFCAT® LE-30 catalyst into a polyether or polyester flexible slabstock, closed-cell or open-cell rigid spray or non- spray or viscoelastic polyurethane foam formulations as a co-catalyst.
