Gloss ketone resin

Diacetone alcohol [123-42-2] (4-hydroxy-4-methyl-2-pentanone) is an almost odorless ketone alcohol that is weakly acidic as a result of rearrangement to the enol form. It is miscible with water and organic solvents except aliphatic hydrocarbons. It acts as a good solvent for cellulose esters and ethers, alcohol-soluble resins, castor oil, and plasticizers. Poly(vinyl acetate) and chlorinated rubber are partially dissolved or swollen. Polystyrene, poly(vinyl chloride), vinyl chloride copolymers, dam-ar resins, resin esters, rubber, bitumen, mineral oils, ketone resins, and maleate resins are insoluble. Diacetone alcohol is used as a high boiler in stoving enamels to improve flow and gloss. 

Resins. A large number of synthetic coating resins (e.g., alkyd, ketone, urea, maleate, and acrylic resins) are available for formulating nitrocellulose combination lacquers. Selection criteria include price, color, influence on solvent release, gloss, hardness, sandability, yellowing, and durability of the final coating. 

Solventhorne paints are mainly alkyd paints with mineral spirit as solvent. Paints based on synthetic resins and two-pack paints with hydrocarbon, ester, or ketone solvents are, however, also used. Gloss ranges from silk-matt to high gloss.
