latex polymer binder, latex coating composition and method for preparing a latex binder

摘要

latex polymer binder, latex coating composition and method for preparing a latex binder are disclosed latex polymers and aqueous coating compositions having excellent freeze-thaw stability, open time, stain resistance, film formation on low temperature, foam resistance, block resistance, adhesion, water sensitivity and a low voc content. Latex polymers and aqueous coating compositions include at least one latex polymer derived from at least one copolymerized monomer or combined with an alkoxylated compound, for example an alkoxylated tristyrylphenol or an alkoxylated tributylphenol. Also provided is an aqueous coating composition comprising at least one latex polymer, at least one pigment, water and at least one freeze-thaw additive. typically, the freeze-thaw additive in an amount greater than 1.3% by weight of the polymer, typically an amount greater than 2% by weight of the polymer, an amount greater than about 4% by weight of the polymer, an amount greater than about 7.5% by weight of the polymer, an amount greater than about 10% by weight of the polymer, or an amount greater than about 20% by weight of the polymer.
