POLYUNSATURATED FATTY ACIDS AS PART OF REACTIVE STRUCTURES FOR LATEX PAINTS: THICKENERS, SURFACTANTS AND DISPERSANTS

摘要

The present invention is directed to a latex paing composition ocomprising polyunsaturated fatty acid containing additives derived from vegetable oils. In preferred embodiments, traditonal water soluble additives such as thickeners, surfactants and dispersants are replaced with polyunsaturated fatty acid containing polymers. The polyunsaturated fatty acid containing additives that lower trhe water resistance of the dry paint film. Additionally, the polyunsaturated fatty acid moieties are capable of oxidati ve crosslinking during the curing process, forming a dry paint film that is mor e durable and water-resistant than traditional latex paint compositions.
