Compositions for the Removal of Silicone Deposits

A solvent composition has an oxygenated solvent and a siloxane solvent. In one embodiment, the oxygenated solvent is propylene glycol methyl ether and the siloxane solvent is hexamethyldisiloxane or octamethyltrisiloxane. In another embodiment, the solvent composition is an azeotrope of propylene glycol n-butyl ether and decamethyltetrasiloxane. The siloxane solvent can be used in any situation where one desires to remove a silicone deposit, e.g., conformal coatings, adhesives, sealants, greases, heat transfer fluids, paints, oils, etc.

Minimum boiling azeotrope of n-butyl-3-hydroxybutyrate and n-undecane and application of the azeotrope to solvent cleaning

A novel minimum boiling binary azeotrope of n-undecane and n-butyl-3-hydroxybutyrate is shown to have utility as a solvent for degreasing of both nonpolar and polar contaminants. The components of the azeotrope are stable against degradation and the composition is largely invariant with pressure, yielding a unique solvent that can be used in cold cleaning and in vapor degreasing at elevated temperatures and over a wide range of pressures.

CLEANING COMPOSITION AND CLEANING METHOD

Provided are a cleaner composition that can exhibit excellent cleaning ability by including a predetermined amount of water, and can also effectively suppress metal corrosion; and a cleaning method thereof. Disclosed is a cleaner composition in a white turbid state including first to fourth organic solvents and water, in which the first organic solvent is a hydrophobic aromatic compound or the like; the second organic solvent is a hydrophobic monoalcohol compound; the third organic solvent is a predetermined hydrophilic nitrogen-containing compound or the like; the fourth organic solvent is a hydrophilic amine compound; the amount of incorporation of water is adjusted to a value within the range of 50 to 3,900 pbw with respect to 100 pbw of the total amount of the organic solvents, and when the cleaner composition is subjected to phase separation, the water concentration in the oil phase is adjusted to a value of 5 wt. % or less.
