Hydrophilic organosilanes
View Patent ↗The present disclosure relates to compositions comprising: an organosilane having the formula: (R 1 )(3-n) (R 2 O) n SiR 3 O(CH 2 CH 2 O) a (C 3 H 6 O) b R 4 wherein: n is 1 or 2; a≥1, b may vary from 0 to 30, with the proviso a≥b; R 1 is a hydrocarbon group containing 1 to 12 carbon atoms; R 2 is hydrogen or an alkyl group containing 1 to 6 carbon atoms; R 3 is a divalent hydrocarbon group containing 2 to 12 carbon atoms; and R 4 is hydrogen, R 1 , or an acetyl group; and at least one of a thermoplastic resin, a thermoset resin, and an elastomer. The present organosilane compositions may be useful for treating various surfaces to render them, among other things, more hydrophilic.
1. A composition comprising:
an organosilane having the formula:
(CH 3 )(CH 3 O) 2 SiCH 2 CH 2 C(CH 3 ) 2 O(C 2 H 4 O) 18 (C 3 H 6 O) 18 H; and
at least one of a thermoplastic resin, a thermoset resin, and an elastomer.
2. The composition of claim 1 further comprising at least one of a mineral filler and a pigment.
3. A surface comprising the composition of claim 1 .
4. The surface of claim 3 , wherein the surface has at least one of anti-fogging properties and water sheeting properties.
5. The surface of claim 3 , wherein the surface is more hydrophilic than a surface lacking the organosilane.
6. The surface of claim 3 , wherein the surface comprises a film.
7. The surface of claim 6 , wherein the film is an agricultural film or automotive window film.
8. A method for improving the dispersion of additives and/or fillers present in a thermoset or thermoplastic resin comprising adding an effective amount of a composition comprising an organosilane of claim 1 to the thermoset or thermoplastic resin.
9. A method for incorporating an organosilane of claim 1 into a thermoset or thermoplastic resin comprising functional groups, comprising contacting the thermoset or thermoplastic resin with the organosilane; wherein the organosilane reacts with the functional groups, thereby forming a substantially permanent bond with the functional groups.
