ПУ клей герметик ST6

ST-6 polyurethane sealant for construction ST6 polyurethane sealant is single Component, low modulus and of strong elasticity. Its especially suitable for the sealing and joint of the multi- porous materials. Uses *Joint filling and sealing for road and bridges made of cement concrete.*Filling joints of the airport runway.*Sealing for the joints of the outwall of precast aerated concrete . *Sealing for constrction joints. Advantages *Excellent adhesion with former cleaned sealant . *Single Component, ready-to-use *Excellent performance,easy to use *High adhesion strengthwith all base materials *Fast cure rate. *Light weight construction material *Good weathering resistance and high durability. *No pollution *Can be painted. Instructions for use Surface preparation Keep surface clean. Clean all dirty, dust, loose particles and paint. Joints can be cleaned by compressed air. The filling material in the joints must be polythene. Priming Use specified primer on concrete and porous surface. Application *Stick protecting adhesive tape on both sides of the joints. *Insert filling materials. *Use the sealant with manual caulking gun or aerodynamic caulking gun. Horizontal seal can be finished by spatula. *Smooth with synthesized cleaner mixed by clean water if necessary. *Tear off the protecting adhesive tape befor the sealant is curing. *Clean all the tools after operating. The curing materials can be only cleaned by machinery methods.
