Compositions having lubricant properties

摘要

New compositions of matter that provide lubricant properties when cured into a coating on a substrate. The compositions are low molecular weight structured polysilicate compositions that have high silanol contents. The polysilicates are combined with a condensation catalyst and allowed to cure on the appropriate substrate. The cured coating has lubricant properties.

1. A composition of matter having the average general formula: wherein the average molar ratio of x:y:z is 0.25-3:4:0.25-3, W is independently selected from the group consisting of Si, Ti, and Zr, and Al; wherein each R1 is an aryl group with the proviso that there is present at least one R1 group; R is independently selected from the group consisting essentially of R1, alkyl groups having 1 to 8 carbon atoms, each R2 is independently selected from a hydroxyl group, an alkoxy group having 1 to 8 carbon atoms, or an R3 is independently selected from the group consisting of hydrogen, alkyl groups having 1 to 8 carbon atoms, or an y has a value of 3 or 4; s has an average value of about 1 to 5; wherein WOy is derived from W(OR3)4, or W(OR3)3, wherein (OR3) is independently selected from the group consisting of —OCH3, —OCH2CH3, —OCH(CH3)2, —O(CH2)3CH3, —OCH2 CH(CH3)2, —O(2-ethylhexyl), acetoxy, and, oximo.
