    Abstract: Coatings for reducing or preventing fouling of surfaces are provided. In some embodiments, the coating comprises a silane compound, a siloxane compound, a phosphonate compound, a silicone polymer such as PDMS (polydimethylsiloxane), or a combination of silane-siloxane-phosphonate-PDMS in various molecular configurations in single monolayer and overlay assemblies. Also provided are related methods for forming the coating as well as coated substrates such as heat exchangers. Embodiments of the coatings are highly hydrophobic with high contact angles and the coated substrates may be used in a variety of industrial applications that require handling of oil-in-water emulsions, process water and produced water from various process operations, including Steam Assisted Gravity Drainage (SAGD) operations.

    Abstract: The method for forming a coating of the present invention includes: a first step of applying a first solution containing a polysilazane to a surface 2a of a metal substrate 2 and heating the first solution to form a first coating 1 on the surface 2a of the metal substrate 2, and a second step of applying a second solution containing a polysilazane to a surface 1a of the first coating 1 and heating the second solution at a temperature lower than a heating temperature in the first step to form a second coating 3 on the surface 1a of the first coating 1, wherein a density of the first coating is less than 2.00 g/cm3, and a density of the second coating is 2.00 g/cm3 or more.
