Cellulose propionate n-butyrate and coating compositions containing same

摘要

Cellulose propionate n-butyrate adapted to be mixed with an oil-modified alkyd resin to form a coating composition. The cellulose propionate n-butyrate has unique properties as an ingredient in such coating composition. The cellulose ester has a n-butyryl content of between about 3% and about 5%, a propionyl content of between about 40% and about 50% and a hydroxyl content of between about 2% and about 3%. The coating compositions are especially useful for protection and appearance when used as a coating on such items as wooden furniture.
