W. N. SHAW has successfully engineered environmentally friendly water-base products for the most challenging applications where lower mold temperatures demand a high level of effectiveness from a release agent. We have custom-formulated our latest water-base products to provide excellent release ease and the desired part finishes that can be easily and safely washed from finished parts. Our water-base releases are designed to minimize buildup on the molds, thus extending the time between tool cleaning.
