Abstract
Paint or varnish composition comprising, as solids: from 10 to 50 parts by weight of at least one polyurethane in aqueous emulsion form; from 10 to 30 parts by weight of at least two acrylic polymers or copolymers in aqueous emulsion form; from 10 to 70 parts by weight of mineral or organic fillers; from 5 to 20 parts by weight of processing aids; and from 0 to 10 parts by weight of crosslinking agent; said composition furthermore comprising from 40 to 150 parts by weight of water, the parts being given by weight of active material in the composition.
Claims18
A paint or varnish composition comprising;
- a) from 10 to 50 parts by weight of at least one polyurethane in aqueous emulsion form;
- b) from 10 to 30 parts by weight of at least two acrylic polymers or copolymers in aqueous emulsion form;
- c) from 10 to 70 parts by weight of mineral or organic fillers;
- d) from 5 to 20 parts by weight of processing aids;
- and
- e) from 0 to 10 parts by weight of crosslinking agent;
- f) from 40 to 150 parts by weight of water;
- wherein said parts are base on the weight of active material in the composition;
- wherein the at least two acrylic polymers or copolymers are chosen in such a way that one has a glass transition temperature between 0° and +5° C. and the other has a glass transition temperature between −40° C. and −30° C.
