JD BL-17 is a delayed-action catalyst designed for use in flexible polyurethane foam formulations.
JD BL-17 catalyst is suited for all types of flexible foam. It is chemically blocked to reduce its catalytic effect during the early stages of the polyurethane reaction. As this reaction progresses however, JD BL-17 catalyst deblocks, providing maximum activity. This allows enhanced control of cream time. When substituted part-for-part for other blowing catalysts, JD BL-17 catalyst will provide delayed cream time without delaying the end of the reaction. JD BL-17 catalyst is also recommended for use in energy absorbing nonrecoverable rigid foam.
