Abstract: A coating composition comprising a carboxy-functional siloxane fluid, an organic titanate and a volatile diluent is applied to a water-impermeable surface and dried. The treated surface has the properties of promoting water-droplet formation, rather than water-film formation when rained upon and releasing frozen water, such as ice, snow, sleet and frost under a very low force.

Abstract: Release agents which are durable when used in the release of sulfur during its processing are claimed. Methods of processing sulfur using the release agents are also claimed. One release agent consists essentially of certain carboxy functional siloxanes, a solvent, and certain titanates. Another release agent consists essentially of a polydimethylsiloxane fluid, a siloxane composed of SiO.sub.2 and (CH.sub.3).sub.3 SiO.sub.1/2 units, a solvent, and a titanate. A third release agent consists essentially of certain carboxy functional siloxanes, a polydimethylsiloxane fluid, a siloxane composed of SiO.sub.2 and (CH.sub.3).sub.3 SiO.sub.1/2 units, a solvent, and certain titanates.
