SEAM GRIP+WP is a polyurethane-based adhesive for repairing lightweight stressed and membrane fabrics. It has the lowest viscosity of the SEAM GRIP / AQUASURE group and forms a thin layer of PU rubber that is self-supporting, flexible and pliable. The adhesive is perfectly waterproof. It enables patchless bonding, butt bonding and also reconstruction of missing material in a 20 mm diameter hole. Directions for use: apply directly from the tube, set in 2 hours, polymerize to full structural strength in 12-24 hours. COTOL 240 or COTOL 240 HV can be used as accelerator. At temperatures above 20 °C, an environment with high relative humidity (90-100 %) significantly accelerates polymerisation.
