Vinyl siloxane oligomer ethoxy functional

1. Product Introduction of the Vinyl siloxane oligomer, ethoxy functional

Vinyl siloxane oligomer, ethoxy functional, Our model SCA-OV71E (equivalent to Dynasylan®6498), is a vinyl silane concentrate (oligomeric siloxane) containing vinyl and ethoxy groups; it is an excellent compatibiliser between inorganic fillers (e.g. kaolin, MDH, ATH) and organic polymers (e.g. EPDM, EVA, PE). It is an adhesion promoter, dispersion and hydrophobation agent in mineral filled compounds. In the presence of moisture, the ethoxy groups of SCA-OV71E hydrolyse to produce ethanol and reactive silanol groups. These silanol groups react with the filler via silicon-oxygen bridges.

3.Application of the Vinyl siloxane oligomer, ethoxy functional :

1. SCA-OV71E is widely used for mineral-filled compounds in the cable industry. EPDM and EVA can be processed into highly filled cable compounds through the adhesion promoting and hydrophobising effect of SCA-OV71E. (The EPDM and EVA polymers are for the halogen-free, non-toxic, environmentally-friendly flame retardant cable compounds (HFFR) based on ATH and MDH)

2.SCA-OV71E can be used in many other applications such as filler and pigment coating, dispersions etc.

3. The high boiling point of SCA-OV71E, 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.

4.Packing Details of the Vinyl siloxane oligomer, ethoxy functional ：

The regular packing of Vinyl siloxane oligomer, ethoxy functional is 25kg plastic pail, 200L steel drums and 1000L immediate bulk container.
