The disclosure relates to a self-healing laminate composition. The composition includes a first, self-healing layer with a self-healing polymer and a second, mechanical layer adjacent to the first layer. The second layer includes any desired polymer, for example a crosslinked polymer, a thermoplastic polymer, or a functional thermoset polymer. Self-healing polymers with dynamic covalent bonds are suitable, for example those with dynamic urea bonds and/or dynamic urethane bonds. A self-healing polymer that is damaged can undergo autonomous repair when separated surfaces re-contact each other due to the soft nature of the self-healing polymer, whereupon reversible bonds can reform to rejoin and repair the damaged self-healing polymer. When the self-healing laminate according to the disclosure is damaged, the self-healing mechanism of the first layer can cause the repair of both layers. The self-healing laminate composition can be used as a coating on any of a variety of substrates to provide self-healing properties to a surface of the substrate.

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.

The invention is directed to a crosslinkable flame-retardant coating composition comprising the following components: a) a dendritic polymer having hydroxyl groups, wherein the dendritic polymer has a hydroxyl number in the range of 80 to 800, b) a polyol having at least 3 hydroxyl groups, c) an ammonium polyphosphate compound, d) a base coat polymer selected from a polycarbamate resin or a polymer bearing carboxyl groups, and e) a crosslinker for crosslinking the base coat polymer selected from a compound having two or more aldehyde groups, acetals or hemiacetals of the aldehydes, or a polycarbodiimide.

Such a cross-linkable flame-retardant coating composition improves the overall appearance of the cross-linked base coating on a substrate and also imparts improved flame-retardancy.
