ABSTRACT:
A surface modifying agent for surface treating a filler in water which comprises 100 parts by weight of a zirconate base or/and aluminate base coupling agent(s) whose unhydrolyzable side chains have a solubility parameter (x) of 6.5-12, and 3 to 30 parts by weight of a nonionic surface active agent blended therewith having an HLB value (y) of 2-30 and containing no protonic hydrogen(s) in its molecule, wherein x and y satisfy a relationship of 4x-24.ltoreq.y.ltoreq.4x-18, as well as another surface modifying agent for the same purpose which comprises a mixture of 100 parts by weight of the above one or two coupling agents having a viscosity of 200 cps or more with 30-3000 parts by weight of a water-insoluble solvent, where the total mol fraction value (z) of the solubility parameters of the unhydrolyzable side chains of the coupling agent(s) and the solvent is 6.5-12, and 3 to 1000 parts by weight of the above nonionic surface active agent blended therewith, wherein z and y satisfy a relationship of 4z-24.ltoreq.y.ltoreq.4z-18. The inventive surface modifying agents have an excellent preservation stability and can perform water repellent treatment of fillers such as calcium carbonate in water.
