Abstract

The aim of this Research is assessment of surface treatment effect with mercapto silane on nano silica (OX50) on mechanical and heat properties of pressure sensitive adhesive. In this study, at first, the surface of nano silica were treated by mercapto silane through sol-gel method. To studying silanization and functional group of nano particles, using TGA, FTIR analysis. Also, to investigating of chemical and physical interaction of treated and untreated particles with polymeric matrix, softening point, adhesion and lab shear tests were performed. Results revealed that the mechanical and thermal properties of pressure sensitive increased with silica treated.
