摘要

The number of waterborne applications is increasing in different coating areas.On the other hand many additives were developed for solvent-borne coatings only.These substances(e.g.light stabilizers)are hydrophobic in nature and can't be used in waterborne systems directly.Progress has been made with the development of waterborne product forms of hydrophobic,water-insoluble additives by using hetero-phase polymerization techniques.This lead to the availability of these additives for a broad range of waterborne paint formulations also.The wood photo-protection against discoloration and broad compatibility can be significantly improved by using these new waterborne product forms of light stabilizers in either film forming or penetrating wood coatings for example.
