DPR® 40 by H.B. Fuller is a low molecular weight, liquid rubber. It contains no additives, peptizers or solvents. It is compatible with many solvents, plasticizers, resins and reinforcements. It increases the polymer’s capacity for fillers and improves the acceptance of non-compatible reinforcements. It reacts into the final rubber matrix. It reduces flow at high temperatures and maintains flexibility at cold temperatures. DPR® 40 is used in adhesives and sealants.
