  • Publication number: 20240101763
    Abstract: An organic functional silane composition is shown and described herein. An organic functional silane composition comprises a mixture of organic functional silane monomers where at least one of the silane monomers comprises two or more alkoxy groups having C1-C2 alkyl groups and at least one of the silane monomers comprises two or more alkoxy groups having an alkyl group of three or more carbon atoms. The organic functional silane compositions can be employed in a coating composition and can improve one or more properties of the coating including, for example, scrub resistance.

  • Patent number: 11760900
    Abstract: A moisture-curable composition is shown and described herein. The moisture-curable composition comprises a moisture-curable resin and a moisture scavenger selected from a cyanoalkylalkoxysilane. The inclusion of the cyanoalkylalkoxysilane in the moisture-curable composition has been found to effectively scavenge moisture and control the rate of curing and viscosity increase in the composition.

  • Patent number: 11702511
    Abstract: Reactive poly(fluoroalkyl-functional siloxane) oligomers, method of making the same, and compositions comprising the same are shown and described herein. The reactive poly(fluoroalkyl-functional siloxane) oligomers are is derived from a hydrolysable fluoroalkyl-functional silanes. Coating compositions comprising reactive poly(fluoroalkyl-functional siloxane) oligomer(s) may be used to form a coating or a film on a substrate and impart hydrophobic and/or oleophobic properties. The reactive poly(fluoroalkyl-functional siloxane) oligomer are more hydrophobic and oleophobic and show better chemical resistance than the hydrolysable fluoroalkyl-functional silane.
