Abstract
A method to improve an efflorescence resistance of film forming compositions. The method comprises the step of adding a coalescent aid comprising a fatty acid ester to the film forming composition, the fatty acid ester has a formula of RCOOX wherein R is a hydrocarbyl having one or more aliphatic carbon-carbon double bonds, and X is selected from a group consisting of: a saturated hydrocarbyl, a hydrocarbyl having one or more aliphatic carbon-carbon double bonds and a substituted hydrocarbyl. These non volatile organic fatty acid ester based coalescents impart superior efflorescence resistance and resistance to color change to film forming compositions, including latex paints, versus conventional, VOC coalescent solvent.
