The Risun Polymer company's core strategy is to design and manufacture the new teconology silane modified STP polymer with technology from western companies and manufacturing and R&D resources in Taizhou & Huai'an cities in China. We will develop polymer as customers' requirements as well as supply advised formulations.
The customers we target are the world's sealant and adhesive and surface coating manufacturers who wish to replace the polyurethane products they make with the safer, and in many cases easier to make silane crosslinked products.
The elimination of free NCO, residual TDI and MDI monomer is essential if we are to protect customers from these hazardous chemicals. Our technical director has had extensive background in paint and adhesives manufacture and R&D. For example slump resistant low modulus PU construction sealant with good adhesion is difficult to manufacture. The use of STP or Hybrid silane crosslinked resin allows the use of precipitated calcium carbonates for good rheology and the ability to use secondary amino silanes as adhesion promoters makes the formulation of these new hybrid sealants much easier.
We have the ability to source polyether polyols from the well known major manufacturers using the DMC catalyst process, and there are now several manufacturers in China. There are also now in China several reputable manufacturers of the special silanes, and we have used them for several years now.
