POLYVEST® ST-E 60

POLYVEST® ST-E 60 is a stereospecific, low viscous and triethoxysilane-terminated liquid polybutadiene having the following composition of double bonds:
· 1,2-vinyl double bonds approx. 22 %
· 1,4-trans double bonds approx. 58 %
· 1,4-cis double bonds approx. 20 %

Typical Applications

POLYVEST® ST-E 60 is used in various fields of application such as:
  • additive for tires
  • adhesive and sealants
  • insulated glass sealants
  • waterproofing membranes and coatings
  • dispersion additive for rubber based formulations

Benefits at a glance

Due to its unsaturated polymer backbone and the terminal triethoxysilane functionalities, the apolar and hydrophobic hydrocarbon resin POLYVEST® ST-E 60 is a highly reactive binder with very good dispersing properties of inorganic fillers. POLYVEST® ST-E 60 exhibits the following features:
  • excellent compatible with solid rubber and recycled rubber
  • high chemical resistance
  • good dispersion and chemical modification with high loading capacity of inorganic fillers
  • high cold resistance by keeping good flexibility at low temperatures
  • good solubility in aliphatics, aromatics and ethers
  • low moisture and gas permeability
  • possibility of moisture induced curing
