Abstract: The present invention provides a film-forming composition comprising a particulate polymer or emulsified liquid pre-polymer, water and a coalescent aid comprising an ester having the formula RCOOX wherein R and X are independently hydrocarbyl or substituted hydrocarbyl, and at least one of R and X contain at least two unsaturated carbon-carbon bonds. The coalescent aid helps lower the minimum film formation temperature of low glass transition temperature coatings and high glass transition temperature coatings and allows optimum film formation at ambient temperatures. The coalescent aid of this coating composition is not volatile like conventional coalescent aids but rather remains part of the film and air oxidizes to cure the film. This coating composition also exhibits properties of adhesion and gloss superior to that of coating compositions containing conventional coalescent aids. Additionally, this coalescent aid can be made from natural or synthetic oils.

Abstract: A film-forming composition comprising a continuous aqueous phase and a dispersed phase, including a foam destabilizing additive comprising an ester, which additive helps lower the amount of foam formed and its subsequent stability and allows for more rapid air release.

Abstract: Stripper compositions for coatings comprise trioxane. An aromatic hydrocarbon and aliphatic alcohol can be added to improve solubility parameters. Xylene and methanol are the preferred co-solvents.

Abstract: Aqueous stripper compositions comprising aqueous emulsions of trioxane have been found to be effective for stripping coatings from surfaces. The composition typically contains water, trioxane, a surfactant and optionally a mixture of cosolvents comprising an aliphatic alcohol, an ester of an aliphatic carboxylic acid and an aromatic hydrocarbon or minimally hetero-substituted derivative thereof. The amount of the organic cosolvent is limited to about 30 wt. % to provide a stripper composition which is less volatile and more biodegradable than conventional stripper compositions.

Abstract: Stripper compositions for coatings comprise an aromatic hydrocarbon, an aliphatic alcohol, and trioxane. Xylene and methanol are the preferred solvents. A useful composition for use at room temperature is 33% xylene, 33% methanol, and 33% trioxane. Trioxane slurries at ambient temperature are also useful for hot dip stripping when heated to a temperature which causes the trioxane to be dissolved.
