CSS V-Wrap 770 is a two-part, 100% solids epoxy for high-strength composite bonding applications. CSS V-Wrap 770 matrix material is combined with CSS V-Wrap carbon and glass fabrics to provide a wet-layup composite for strengthening of structural members. It is formulated to provide high elongation to optimize properties of the CSS V-Wrap composite systems. It provides a long working time for application, with no offensive odor. CSS V-Wrap 770 may be thickened with fumed silica to produce a tack coat/putty or a finishing coat, depending upon the project requirements. CSS V-Wrap 770 contains no volatile organic compounds (VOC) or solvents.
