Styrene acrylics
Styrene acrylics are copolymers of various acyl esters and styrene. They generally possess good hydrophobicity and alkali resistance. UV stability is usually lower than that of pure acrylics.
Styrene acrylics are used, for example, in interior dispersion paints, silicate paints and plasters, dispersion plasters and adhesives, occasionally also in exterior paints.
