IsoPour 20C45

IsoPour 20C45 is a slow reacting two component rigid polyurethane foam that exhibits low viscosity and exotherm. Due to its slow initiation it is suitable for mixing by either hand or machine. It has very good flow and cavity filling due to its speed and expansion of approximately 32 times its liquid volume. It is suitable for void fill; flotation; cavity insulation; or wherever a low density rigid foam is needed.
