FIELD: production of paint-vehicle composition of cold and hot drying. ^ SUBSTANCE: claimed composition contains 44 % acryl polymer in solvent as film forming agent; 40 % acryl latex as thickener; 25 % ammonia aqueous solution as medium pH adjusting agent; solution of isothiasoline derivatives such as 1,2-hydroxy-5,8,11-trioxadodecane, 1,3-bis(hydroxymethyl)-urea, 1,6-hydrohy-2,5-dioxyxexane as conserving agent; emulsion of ether and siloxane copolymer in fumigated silica as antifoaming agent; water as solvent; and additionally ethanol in specific component ratio. Obtainer film has impact strength of 60-63 cm and desiccation time at (20±2)°C is 3-5 min and at (60±5)°C is 13-15 s. ^ EFFECT: composition for film formation having improved impact strength. ^ 2 tbl, 10 ex |
