| Description |
Siwin-O6498 is a vinyl silane concentrate (oligomeric siloxane)containing vinyl and ethoxy groups. A colourless nearly odorless low-viscosity liquid. An excellent compatibiliser between inorganic filler (e.g. kaolin, MDH, ATH) and orgainc polymers (e.g. EPDM, EVA, PE). The high boiling point of Siwin-O6498, together with its high flash point, gives it outstanding advantages with respect to safety and handling during processing. From an environmental viewpoint it should be noted that the amount of released hydrolysis ethanol (VOC) is significantly reduced compared to monomeric vinyl silanes. The high boiling point of Siwin-O6498, together with its high flash point, gives it outstanding advantages with respect to safety and handling during processing. From an environmental viewpoint it should be noted that the amount of released hydrolysis ethanol (VOC) is significantly reduced compared tomonomeric vinyl silanes. |
| Application |
Siwin-O6498 is excellent as an adhesion promoter, dispersion and hydrophobation agent in mineral field compounds. In the presence of moisture, the ethoxy groups of Siwin-O6498 hydrolyse to produce ethanol and reactive silanol groups. These silanol groups react with the filler via silicon-oxygen bridges. The vinyl functional groups of Siwin-O6498 react with the polymer phase in the presence of radicals: A major field of application for mineral filled compounds is the cable industry. EPDM and EVA can be processed into highly filled cable compounds through the adhesion promoting and hydrophobising effect of Siwin-O6498. The EPDM and EVA polymers with Siwin-O6498 are for the halogen-free, non-toxic, environmental-friendly flame retardant cable compounds (HFFR) based on ATH and MDH. In addition, Siwin-O6498 can be used in many other applications such as filler and pigment coating, dispersions. Typical property improvements obtained by using Siwin-O6498 in filled polymers are: Improved filler dispersion; Good processability; Significantly reduced water-uptake excellent balance; Between tensile strength and elongation at break at a high-level improved chemical resistance; Strongly reduced tendency to stress cracking; Higher impact strength; Higher abrasion resistance. |
