New SU Polymer Adhesives

SU polymer adhesive is a mixture of polysiloxane and polyurethane resin. It has fast curing and excellent transparency. It does not use toxic solvents such as toluene. It is a solvent-free, environmentally friendly multi-purpose adhesive. In addition to polyolefin, silicone resin, fluorine resin material, widely used in metal, glass, plastics, rubber, leather, cloth, paper and other species and dissimilar materials. When used as a home adhesive, when the curing temperature is 60° C. and the initial tack cure is about 4 minutes, the adherend does not move, and after 1 hour, it reaches the use strength, and 24 hours is completely cured. It has a shorter curing time than silicone adhesives. When it is bonded to transparent materials, it does not yellow and remains colorless and transparent.
