Application of Silane Synergist DOFLOW DST-100H in Silica Filled Compound
The application of silane synergist DOFLOW DST-100H(referred to as DST-100H)in silica filled compounds was studied.The results showed that,in the silane coupling agent Si75 system,the addition of DST-100H could improve the processability of the compound,increase the elongation at break and tear strength of the vulcanizate,and had a positive effect on improving wet-skid resistance and reducing rolling resistance.In the silane coupling agent Si747 system,the addition of DST-100H could effectively improve the processability and scorch safety of the compound,increase the tensile strength,elongation at break and tear strength of the vulcanizate,reduce the Payne effect of the compound,and improve the dispersion of silica.
