Aqueous Vinyl Coating Compositions

摘要

Aqueous coating composition comprising a blend of 20 to 60 wt % of a multistage vinyl polymer (A) comprising 5 to 40 wt % of at least one hard polymer stage (i) having a Tg>=50° C. and 95 to 60 wt % of at least one soft polymer stage (ii) having a Tg<=-5° C.; and 80 to 40 wt % of a vinyl oligomer-polymer (B) comprising 15 to 50 wt % of at least one alkaline soluble oligomer (iii) and 85 to 50 wt % of at least one vinyl polymer (iv) having a Tg in the range of from -20 to 30° C.
