Boctok silanes are used in adhesives and sealants as tackifiers, surface modifiers, crosslinkers, moisture absorbers and sealants and can be used to impart the following properties to adhesives and sealants: reducing adhesive viscosity, improving dispersion of fillers and pigments, improving processability and adhesion to the substrate, improving wet and dry substrate strength and bond durability, preventing premature vulcanization of the adhesive, improving storage stability, improving uniformity of adhesive cure, improving elongation at break, improving elongation at break, improving elongation at break, improving elongation at break, improving elongation at break, improving elongation at break, improving elongation at break, improving elongation at break, improving storage stability. Homogeneity, increasing elongation at break.
