Release coating material is an important component of adhesive tape products. The release coating surface protects adhesive surface while in contact with the adhesive coating surface, and then easily peeled off from the surface when the adhesive is to be used. In order to prevent the release material from being transferred to the adhesive surface, some polymer or silica micro-particles are coated together on the release surface. However, there is a problem that these particles remain on the adhesive surface and act as foreign substances on the product. In this study, in order to overcome this problem, the affinity between the particles and the adhesive surface was reduced by modifying the surface of silica micro-particles to be hydrophobic. As a result, it was possible to prevent the transfer of particles, and this phenomenon and the surface modification of the particles were analyzed by SEM and IR-spectroscopy.
