A WATERBORNE BINDER COMPOSITION AND USE THEREOF

摘要

The present invention relates to a waterborne binder composition comprising a water dispersible polymer binder and a coalescing agent, which comprises triesters selected from the group consisting of tripropionin (triester of glycerol and propionic acid), tributyrin (triester of glycerol and butyric acid), tri-isobutyrin (triester of glycerol and isobutyric acid) or trivalerin (triester of glycerol and valeric acid) or combinations of two or more of these. The binder in the composition of the present invention is a homo- or copolymer comprising monomer units of acrylate, methacrylate, vinyl acetate and/or units of urethane or urethane/urea. In addition to the water dispersible polymer binder and the coalescing agent the composition may contain pigments, fillers and additives. The invention also covers the use of the binder composition in waterborne paint, adhesive or sealant.
