SRI 30% Clear Sealer
Acrylic Concrete Sealer
SRI 30 Clear Sealer- is a pure acrylic polymer solution. It naturally resists the yellowing process. SRI 30 Clear Sealer – leaves a film forming membrane which achieves both a protective and decorative finish.
SRI 30 Clear Sealer – coatings dry by solvent evaporation to a tough protective film that adheres well to metal, concrete, and other masonry surfaces. The coatings have excellent resistance to U.V. light, water, and a wide variety of chemicals. Typical properties of SRI 30 Clear Sealer are given in Table I.
