Embodiments described herein relate generally to systems and methods for creating durable lubricious surfaces (DLS) via interfacial modification. The DLS can be prepared via a combination of a solid, a liquid, and an additive that modifies the interface between the DLS and a contact liquid, resulting in an interfacial layer that acts as a lubricant and/or protective coating between the DLS and the contact liquid. The lubricating effect created between the additive and the contact liquid results in enhanced slipperiness, as well as the protective properties that can help with durability of the DLS.

One aspect described herein is a polyurethane, texture coating composition, sprayable on a substrate by means of conventional spray equipment and at conventional pressures and ambient temperatures, in one or more layers to a film thickness of up to about 30 mils, comprises a resin component having hydroxyl functionality, an isocyanate functional curing component, an organotin catalyst, a polyethylene wax particle and a silica particle. The composition may optionally include an extender pigment and a colorant. Advantageously, the coating compositions of the present invention provide polyurethane films with texture, having excellent physical properties, slip properties with abrasion resistance, solvent and UV resistance and adhesion to prepared substrates. The compositions are particularly useful to repair textured substrates, add desired textures to substrates and form sprayable vehicle bedliners.
