Abstract
This invention relates to non aqueous non-volatile alkylated siloxane compositions having low VOC and vapor pressure of about 31 millimeters of mercury at 20° C. consisting essentially of a mixture of a linear or open-chain methyl alkylated siloxane having two silicon atoms and a siloxane having three silicon atoms alkylated with methyl groups.
Claims9
Siloxane compositions having low VOC and a vapor pressure of about 31 millimeters of mercury at 20° C. consist essentially of from about 55 to 75 parts by weight of an alkylated open-chain siloxane having two silicon atoms and from about 25 to 45 parts by weight of an alkylated open-chain siloxane having three silicon atoms.
A siloxane composition for cleaning metal having a low VOC and a vapor pressure of about 31 millimeters of mercury at 20° C. consisting essentially of from about 62 to 65 parts by weight of hexamethyldisiloxane and from about 35 to 38 parts by weight of octamethyltrisiloxane.
A process for removing and cleaning oleaginous materials from a metal surface which comprises adding an effective amount of a siloxane composition onto said oleaginous-containing metal surface and subsequently cleaning the oleaginous material from the metal surface:
- said siloxane composition having a low VOC and a vapor pressure of about 31 millimeters of mercury at about 20° C. and consist essentially of from about 55 to 75 parts by weight of an alkylated open-chain siloxane having two silicon atoms and from about 25 to 45 parts by weight of an alkylated open-chain siloxane having three silicon atoms.
