Description
SURPRO 688 is a pigmented high performance, three-component urethane/acrylic sealer formulated specifically to protect surfaces that are subject to the heaviest use conditions. The SURPRO 688 package includes Part A - Resin, Part B - Cure and a container of selected pigment dispersion (Tint). SURPRO 688 is suitable for concrete and other cementitious surfaces, as well as a topcoat for existing sealers and coatings. SURPRO 688 is chemically resistant, highly durable, and cures hard within 24 hours of application. The low odor formula is designed to allow application without disruption of normal operations - ideal for areas where solvent odors from traditional acrylic or polyurethane coatings are not tolerated.
