- 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.
