Delayed Action Catalysts

Our Delayed Action Catalysts allow polyurethane manufacturers to achieve precise curing control and extended pot life. Designed for complex molding and large-scale foam production, these catalysts reduce premature gelation and improve processing safety. We serve OEM producers needing balanced reactivity in insulation, automotive, and elastomer systems. These catalysts are also compatible with HFO-based formulations and meet modern environmental standards.

Delayed Action Catalysts

Delayed Action Catalysts feature modified amine or organometallic structures that activate under heat or specific reaction conditions. They remain dormant during initial mixing, allowing uniform distribution before reaction onset. The delayed mechanism enhances mold filling and cell uniformity while preventing early viscosity rise. They are suitable for flexible and rigid foam systems requiring extended processing windows.
