Abstract: Disclosed are a silica sol composition including silica, an anionic dispersant, two or more epoxy silane coupling agents, and an organic solvent, and a method for preparing the same. In the silica sol composition, a uniform surface modification of silica particles may be achieved by using an anionic dispersant and two or more epoxy silane coupling agents, and it is possible to effectively enhance the compatibility between a silica filler whose surface is modified with an epoxy group and a resin which is an underfill composition.

Abstract: Disclosed are a silica sol composition including silica, an anionic dispersant, a cationic dispersant, an epoxy silane coupling agent, and an organic solvent, and a method for preparing the same. In the silica sol composition, a uniform surface modification of silica particles may be achieved by using an anionic dispersant and a cationic dispersant, and it is possible to effectively enhance the compatibility between a silica filler whose surface is modified with an epoxy group and a resin which is an underfill composition.
