Uses
Butyl acrylate is primarily used in the production of homo and co-polymers emulsion for use in water based architectural and industrial paints. Polymers with butyl acrylate can also be used in manufacturing cleaning products, leathers industries, antioxidant agents, plastics, enamels, inks, adhesives, sealants, textiles, caulks and paper finishes. The acrylate functionality allows it to be used as a chemical intermediary.
