ABRADABLE POWDER COATING MANUFACTURED WITH SOLVENT-FREE LIQUID POLYMER RESIN BASE COAT
20230033008 · 2023-02-02 ·

An abradable coating is formed on a mechanical part from a polymer resin-containing powder deposited over a polymer resin-containing liquid that is substantially free of volatile organic hydrocarbons. The liquid and the powder are then cured together to form an abradable coating. The polymer resin-containing powder may include a first thermosetting resin and a filler having a melting point above a cure temperature of the first thermosetting resin. The interactions of the powder and the liquid result in a durable abradable coating. Because the liquid is substantially free of volatile organic hydrocarbons, overspray may be recovered and used to coat other parts.

Polymeric nanocomposite based sensor and coating systems and their applications

A system and method for direct and/or active detection and monitoring of civil engineering or other infrastructural structures, and in a preferred embodiment, for hydrocarbon leakage in oil and gas pipelines, storage structures, and/or transportation structures. Particularly, the system and method relate to various nanocomposite sensor coating and data gathering systems. In one embodiment, the apparatus includes a single measurement sensor coating (thin film) sensor. Other embodiments relate to multiple measurement sensor coating systems. The sensor is comprised of either a discrete conductive filament layer, or a single or multiple mesh of interwoven filaments of conductive material in one direction and nonconductive material in a perpendicular direction, as a substrate coated with sensitive coating materials to form a sensor grid. Various embodiments of the sensor coating and their applications are also disclosed.

One-component waterborne self-healing epoxy formulation

Embodiments provide a self-healing coating formulation comprised of a one component waterborne epoxy-amine adduct resin system and a microencapsulated healing agent. The self-healing coating formulation hardens to a protective material upon application to a substrate. Components in the protective material and microencapsulated healing agent are uniquely synergistic with each other such that, upon degradation of the protective material, microcapsule rupture causes release of the healing agent, whereby components of the healing agent react with components of the protective material to increase adhesion maintenance and corrosion resistance of the protective coating.
