ABSTRACT:
Liquid coating solutions impart hydrophobicity to substrate surfaces (e.g., glass) and include a silane, preferably octadecyltrichlorosilane (OTS), dissolved in a liquid paraffinic solvent. Preferred liquid paraffinic solvents are normal (straight chain) liquid parrafins having between 10 to 20 carbon atoms per molecule exhibiting flash points (ASTM D93) of between about 70° C. to about 160° C., and initial boiling points (ASTM D86) of between about 185° C. to about 300° C. The OTS will be present in the hydrophobic solutions in amounts sufficient to form a hydrophobic coating on surfaces of substrates on which the solutions are applied, and most preferably will be present in amounts ranging between about 0.25 to about 2.5 molar. Applying a coating of the solution onto a substrate surface will allow the OTS for form a self-assembled monolayer thereon imparting hydrophobicity to the substrate as determined by a high contact angle of at least about 100°.
