FIELD: chemistry.
SUBSTANCE: coating composition comprises a reaction product of a tetraalkoxyorthosilicate or a partially condensed oligomer thereof with a polyester resin containing hydroxyl groups. Polyester resin modified with a silicate is prepared by heating a mixture of alkoxyorthosilicate or a partially condensed oligomer thereof in the presence of a catalyst with a polyester resin containing hydroxyl groups.
EFFECT: high content of solid particles or a low VOC content combined with low viscosity, the compositions are able to dry out quickly and cure in ambient conditions, and can be performed in one package.
