WEICON Flex 310 PU is permanently elastic, strong, paintable, and resistant to weather, ageing, fresh and sea water and free of silicone. This versatile adhesive and sealant based on Polyurethane (PUR) can be used for the bonding and sealing of numerous materials such as metals, plastics, ceramics, wood, glass and stone. It can be used in tank and apparatus engineering, carriage, container and vehicle construction, in ventilation and air conditioning systems, the energy and electrical industry, and in all applications where silicones or products containing silicones are not suitable.
LOCTITE® AA 3951 is a low viscosity, high-elongation light cure adhesive designed for applications where a fast curing, highly flexible adhesive is required. Ideal for bonding plasticized PVC, TPEs, and thermoset rubbers. It also maintains high adhesion to rigid substrates such as polycarbonate, ABS, Acrylic, HDPE (when treated), PP (when treated) and more. You can expect a fixture time of just 5 seconds.
