Definitions
- the present invention relates to a surface-modified inorganic oxide powder used in a polar resin compound such as a polar resin adhesive for the purpose of improving viscosity, reinforcing filling property, adhesiveness, etc., and a method for producing the same and a method for producing the same. (Background technology)
- Such surface-modified inorganic oxide powders are widely used as fillers for polar resins such as epoxy resins, urethane resins, and polyesters for the purpose of thickening and thixotropic properties.
- polar resins such as epoxy resins, urethane resins, and polyesters
- thickening, thixotropy and stability over time are important factors.
- an additive which can impart high viscosity and thixotropic properties with a smaller amount of addition than before and has excellent stability over time.
- the present applicant has previously proposed an inorganic oxide powder that is useful for improving the fluidity of a powder material, preventing solidification, and adjusting charge, in addition to such thickening and reinforcing filling properties (Japanese Patent Application No. -59533).
