The embodiments herein relate to a substrate coated with a multi-layer coating system including: optionally a primer layer applied to the substrate and deposited from a primer coating composition; a tie-coat layer applied to the substrate or to the optional primer layer, deposited from a tie-coat composition including a binder polymer obtainable by copolymerizing a mixture of ethylenically unsaturated monomers, the binder polymer having curable alkoxysilyl functional groups. The substrate can include a topcoat layer applied to the tie-coat layer, and deposited from a non-aqueous liquid foul release coating composition including a curable resin system including i) a curable polymer and optionally ii) a curing agent and/or a catalyst, where the non-aqueous liquid foul release coating composition is essentially free of a curable polysiloxane.

Shelf-stable low temperature cure coating compositions that include a hydroxy-functional resin, a crosslinking agent, and a catalyst that does not catalyze the crosslinking reaction between hydroxy-functional resin and the crosslinking agent contained therein, but instead between a hydroxy-functional resin and a crosslinking agent contained in a different low temperature cure coating composition. In addition, low temperature cure composite coatings that include: a waterborne basecoat containing a first hydroxy-functional resin, a first crosslinking agent, a first catalyst, and an organic solvent; and a solventborne topcoat containing a second hydroxy-functional resin, a second crosslinking agent, a second catalyst, and water, where the first catalyst migrates into the topcoat from the basecoat and catalyzes the reaction between the second hydroxy-functional resin and crosslinking agent, and the second catalyst migrates into the basecoat from the topcoat and catalyzes the reaction between the first hydroxy-functional resin and crosslinking agent.

The present disclosure provides fluid barriers as well as systems and methods of forming fluid barriers. The method includes cleaning, via a blast media, a first side of a component and heating the component to a first temperature. Subsequently, the component is cleaned using a solvent. Subsequent to heating at least the component, a primer coating layer is formed on the first side of the component, and a topcoat layer is formed in contact with the primer coating layer. A primer coating material can be heated to a second temperature prior to formation of the primer coating layer. The first temperature can be different than the second temperature.
