High solid, self-thickening copolymer latex for sealant

Abstract

A copolymer latex for sealant. The said composition may be used in various applications such as non-pigmented and pigmented sealants for gap filling, waterproofing, in construction and other applications. The copolymer latex composition includes an organic acid fraction, an amide derivative fraction, an acrylic monomer fraction, and a surfactant fraction. The copolymer latex composition may include at least 55% solids of polymerization product of one or more monomers. The said composition is such that the copolymer latex shows properties such as self-thickening ability and good water repellence. The said composition at dry film thickness of about 2 mm provides transparency. In addition, the copolymer latex provides properties like hydrophobicity, tensile strength, elongation efficiency, and low foaming.
