ECOPOWER Crosile®1098 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 plymers (e.g. EPDM, EVA, PE).
The high boiling point of Crosile®1098, 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 significant'y reduced compared to monomeric vinyl silanes.

Chemical Properties
ECOPOWER Crosile®1098 is excellent as an adhesion promoter,dispersion and hydrophobation agent in mineral field compounds. In the presence of moisture, the ethoxy groups of Crosile®1098 hydrolyse to produce ethanol and reactive silanol groups. These silanol groups react with the filler via silicon-oxygen bridges. The vinyl functiona groups of Crosile®1098 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 Crosile®1098.
The EPDM and EVA polymers with Crosile®1098 are for the halogen-free, non-toxic, environmentall-friendly flame retardant cable compounds (HFFR) based on ATH and MDH.
In addition, Crosile®1098 can be used in many otherapplications such as fller and pigment coating, dispersions
