| WC-753 A/B is a two part, translucent 55 Shore D polyurethane adhesive/coating system designed to repair cracks and scratches. WC-753 A/B is also used to bond dissimilar substrates and has excellent adhesion to plastic surfaces. It is particularly suited for bonding or clear coating a wide variety of porous, synthetic, or natural substrates, such as rigid or flexible foamed plastics, fabrics, wood or modeling board. WC-753 A/B will bond construction materials such as polystyrene insulation board, rigid polyurethane foam, and Neoprene rubber. |

| Generally, for most coating or adhesive applications, ambient temperature curing is adequate. However, optimum physical properties are obtained by moderate post-curing WC-753 for 2 - 4 hours at 120 - 140° F (49° - 60°C), after tack free and dry to touch at ambient temperature cure. |
