The present invention relates to a filler surface-treated with a curing agent having an alkoxysilyl group or an epoxy resin having an alkoxysilyl group exhibiting improved physical properties in a composite containing a filler, a method for producing the same, a composition comprising the same, and uses thereof. According to the present invention, a filler surface-treated with at least one surface treatment agent selected from the group consisting of an epoxy resin having at least one alkoxysilyl group and at least two epoxy groups, a curing agent having at least one alkoxysilyl group, and a hydrolyzate thereof, Processes for their preparation, compositions comprising them and their uses. The composition comprising the epoxy resin having an alkoxysilyl group of the present invention or the filler surface-treated with a curing agent is not particularly limited as long as the composition has properties such as mechanical strength, heat resistance, thermal expansion characteristics, Physical properties such as heat radiation properties, electrical conductivity, and flame retardancy are improved. |
