Designed for use in rigid polyurethane foams, Polycat™ 204 helps producers maximize foam performance and achieve up to 6–8 months of system stability when incorporating Next Generation Hydrofluoroolefin Blowing Agents, such as Honeywell's Solstice LBA. Non-emissive additive will help industry adopt HFO blowing agents with reduced global warming potential, while also minimizing VOC emissions.
