  • Publication number: 20110201721
    Abstract: Disclosed in this specification is a method and composition for producing a coating of a poly(vinyl chloride) (PVC) resin from an acetone-based solution. The solution includes a coating facilitator with terpineol and/or tertbutyl acetate. The coating facilitator also includes a second compound with a boiling point of at least 100° C. that acts to promote the solubility of the PVC resin. Also disclosed is an acetone-based solvent system that includes an additive selected from a terpene, diacetone alcohol and t-butyl acetate.

  • Patent number: 7833959
    Abstract: The present invention relates to a method to decrease the flammability of normally flammable alcohols and solvents. The additive is Alpha Terpineol, which will increase the flash point of flammable alcohols or solvents, by blending the Terpineol into the flammable solvent or alcohol. Solvents such as acetone, methanol, ethylacetate, ethanol and xylene, to name a few, increases flash points by 50° C. to 60° C., by addition of 12-14% terpineol. The said solvent can then be blended with other organic solvents to produce performance solvents, such as paint strippers with flash points greater than 140° F. and meet Federal and state Volatile Organic Compound regulations.

  • Publication number: 20100247784
    Abstract: A method for applying a coating meeting a predetermined volatile organic compound (VOC) standard. The compound functions as a coating and plasticizer. The inventive method involves mixing acetone and terpene alcohol, or terpineol, to form a solvent system with a flash point of at least 140° F. A resin is solubilized into the solvent system and forms a coating. The coating is cast over substrate surfaces to cure and dry. The solvent system produced by the inventive method can also be used in other applications including as a cleaning composition.
