Polycat 520 is a tertiary amine-based foaming catalyst that facilitates urea (water-isocyanate) reactions in a variety of hard and soft polyurethane foam applications. It is the industry standard foaming catalyst for hard foams and is used in MDI-based on-site casting polyurethane systems, such as rigid appliances. It is also used in combination with trimer catalysts in PIR laminated paperboard formulations. Polycat 520 can also be used in TDI, TDI/MDI, MDI High Resilience (HR) soft molding foams as well as self-crusting and microcellular systems. It has a shelf life of 36 months.
