FIELD: chemistry.
SUBSTANCE: invention relates to film-forming additives for use in paint formulation and in coating compositions. Described three-component coalescent additive with low content of volatile organic compounds, which contains about 60 to about 90 wt % diethylene glycol dibenzoate, about 15 to about 50 wt % dipropylene glycol dibenzoate and about 20 to about 90 wt % 1,2-propylene glycol dibenzoate from the total weight of the composition.
EFFECT: use of said additive enables to obtain a paint or coating with low content of volatile organic compounds, stable viscosity after three freezing/thawing cycles and equivalent excellent wet edge retention time/film edge setting time, lustre, scratch resistance and blocking resistance compared to prior art.
