Process for hydrophobicizing particles, and their use in dispersions

摘要

Particles are hydrophobicized by treatment with a compound containing amino and silane groups. The invention is particurlarly useful for treating hydrophilic inorganic particles. The treated particles can be used, for example, as a compound agent for polymers. The production and use of a predispersion or concentrate comprising a major amount of the treatemt particles and a binder is also described.
