Vinyl Silane Oligomer

SiSiB® VP6180 is a vinyl silane concentrate. It is a colorless, nearly odorless liquid. 

SiSiB® VP6180 is suitable as an adhesion promoter between inorganic materials (e.g. minerals, glass, metal) and organic silicone polymers. The high boiling start of SiSiB® VP6180, together with its high flash point, gives it several advantages with respect to safety and handling. It is more environmental as the amount of released hydrolysis alcohol (VOC) is considerably less than for monomeric silanes.

SiO2 content



  • SiSiB® VP6180 vinyl silane can be used in filler, pigment treatment, dispersions and etc.

  • Filled EPDM and EVA can be processed into cable compounds through the adhesion promoting and hydrophobising effect of SiSiB® VP6180. It can also be used for halogen-free, non-toxic, environmentally-benign flame retardant compounds (HFFR) based on ATH and MDH.

  • Typical property improvements obtained by using SiSiB® VP6180 high heat silicone in filled polymers include:

    Improved filler dispersion

    Increased heat resistance

    Improvement of creep behavior at increased temperature

    Improved chemical resistance

    Strongly reduced tendency to stress cracking

    Higher impact strength

    Higher abrasion resistance

    Good processability

Packing and Storage

  • SiSiB® VP6180 is supplied in net weight 25Kg, 50Kg, 200Kg drum.

  • In the unopened original container SiSiB® VP6180 has a shelf life of one year in a dry and cool place.
