Advantages of Industrial adhesives based on Risun ****0DS&****0DS: 

1. The adhesives used in these areas have much higher tensile strength requirements, usually starting at about 3.0 Mpa tensile at break and can go up to 6.0 Mpas. These adhesives need good adhesion to the surfaces bonded, and usually are required to have a fast cure at room temperature from 5 minutes to *5 minutes. 

2. The adhesives need to have high tensile strengths with some elongation and good tear strength, which these Risun Polymers can accommodate. 

3. For Adhesive manufacturers these adhesives need different Risun Polymers compared to Construction markets, as the adhesives contain very little plasticizer and the reinforcing additives such as precipitated calcium carbonate and carbon black are processed with higher levels of catalyst and adhesion silanes. 

4. These requirements of the Automotive and Industrial markets can be met by the use of the dimethoxy silane based Risun ****0DS and Risun ****0DS Polymers, where the adhesion of this molecule has been shown to be improved, and the curing mechanism releases small amounts of methanol with no bubbles like fast polyurethane adhesives. These polymers are very easily processed with Precipitated calcium carbonates and carbon black powders, and produce very tough adhesives with good tensile and tear strengths. 

5. These Risun ****0DS and R****0DS Polymers can also be mixed with some trimethoxy Resins in a second step such as Risun R***0T to produce a faster curing system where there is also less of the tin Diketonate catalysts added for faster curing. 

6. The R****0DE and R****0DE Polymers use the more environmentally friendly tin diketonate catalyst and secondary amino silane chemicals as the curing mechanism. They also reduce the amount of methanol released.
