POLYCAT® 41

POLYCAT® 41 is a tertiary amine catalyst employed in a wide variety of polyurethane foam and non-foam applications. It is a gel catalyst with added mild PIR selectivity, making it suitable for a wide variety of rigid polyurethane and polyisocyanurate foam and non-foam applications. It is recommended as a co-catalyst in combination with other polyurethane and polyisocyanurate catalysts, particularly in formulations with an isocyanate index greater than 105–110.

Recommended Applications
  • POLYCAT® 41 is a gel catalyst with additional mild PIR selectivity used in a wide variety of rigid polyurethane and polyisocyanurate foam and nonfoam applications.
  • It is recommended for use as a co-catalyst with other polyurethane and polyisocyanurate catalysts, particularly in formulations with an isocyanate index greater than 105 – 110.
  • POLYCAT® 41 has a certain hydrolysis sensitivity. Hence stability testing of formulations containing POLYCAT® 41 is highly recommended.
  • POLYCAT® 41 may be used in conjunction with suitable co-catalysts from the DABCO®, POLYCAT® and/or KOSMOS® range, based on specific formulation requirements.
  • In PIR formulations, POLYCAT® 41 can be used as co-catalyst in conjunction with trimerization catalysts such as products of the KOSMOS® and DABCO® TMR series.
  • POLYCAT® 41 and potassium/metal catalyst should not be pre-blended as it might lead to incompatibilities.
  • Separate dosing and/or blending into the polyol is preferred.
  • The optimal concentration will depend on specifics of the formulation.
