* Approved for indirect food contact (21CFR 178.3570) In support of providing products with unparalleled worker safety, Price-Driscoll continues to maintain the broadest selection of non-flammable mold releases in the industry. Our NF formulation utilizes a non-flammable propellant and non-flammable solvent suggested by the S.N.A.P. sector of the EPA. For use on steel molds only. Chose NF when you absolutely must have the lowest-flammability product on the market. A new concept of solvent-less, low-VOC release agents engineered to be effective with the broadest possible range of materials. Release agent has a fast evaportation rate and provides a dry finish. Low-VOC formulation contains no chlorinated solvents, is non-ozone depleting with very low global warming potential. GP formulation supports our triple commitment to worker safety, environmental responsibility and business productivity. S is our most economical offering, while still maintaining our high performance standards. Maintains the same performance characteristics of our other formulations, but uses a flammable hydrocarbon solvents and propellants to keep cost down. Contains no chlorinated solvents, is non-ozone depleting, and has virtually zero Global Warming Potential. Choose the “S” formulation when cost is the determinant factor.
