- 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
