Stain Release Additive
3M™ Stain Resistant Additive SRC-220 is an aqueous fluoropolymer solution that adds stain resistance and release characteristics to porous surfaces such as concrete, grout, unglazed tiles, granite, clay, slate, limestone and terra cota. SRC-220 can be diluted with water, water-soluble organic solvents and water solvent mixtures to create a penetrating sealer for porous surfaces, providing water and oil repellency. SRC-220 concentrate can also be used as an additive to provide stain resistance and stain release to many coating and sealer formulations, and to various construction materials.
