A POLYURETHANE AND VINYL POLYMER BASED RECYCLABLE AQUEOUS COATING COMPOSITION

摘要

A recyclable aqueous coating composition comprising a combination of a polyurethane polymer (A), a vinyl polymer (B) having a Tg >= 20°C, a Mw > 50,000 and an acid value < 40mgKOH/g and a vinyl polymer (C) having a Tg >= 70°C, a Mw from 15,000 to 50,000 and an acid value >= 40 mgKOH/g where the ration of (A)+(B):(C) is in the range of from 95:5 to 65:35.
