摘要:
The present disclosure provides multilayer films including a first layer disposed adjacent to a painted surface, the first layer comprising, consisting essentially of, or consisting of a semi-polar polymer such as a polysilazane (PSZ), polysiloxazane or a copolymer of polysilazane and polysiloxane repeat units (e.g., a polysiloxazane); and an outer layer disposed opposite the painted surface, the outer layer comprising, consisting essentially of, or consisting of a non-polar material such as a crosslinked hydroxy-terminated polydimethylsiloxane or a crosslinked silanol-terminated polydialkylsiloxane.

Methods of protecting a submerged surface include applying an adhesion-promoting layer onto a surface. An inner polymer layer is applied onto the adhesion-promoting layer. The inner polymer layer is impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage. An outer polymer layer is applied onto the inner polymer layer. The outer polymer layer is impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage and that repels biofouling organisms to prevent invasion of the inner polymer layer.

Provided herein is a method of forming paint films using a three-coat one-bake system comprising applying a white base coat comprising titanium oxide to a polyolefin substrate comprising a primer, applying a light colored mica base coat to the white base coat wet-on-wet and then applying a clear coat to the mica base coat wet-on-wet, and then heating and hardening the polyolefin substrate comprising the while base coat, the mica base coat, and the clear, wherein the primer, white base coat and mica base coat each comprise from 0.2 to 5.0 parts by weight of a biphenylphosphate compound which can be represented by formula (1) per 100 parts by weight of resin solid fraction. Also provided herein are articles manufactured according to this method of forming paint films.
摘要:
Disclosed herein is a method for forming a multilayer coating film by sequentially coating an intermediate coating material composition, a base coating material composition and a clear coating material composition on a metal for a motor vehicle body or resin material and then thermally curing the compositions, where the clear coating material composition is obtained by mixing a main agent (A) and a curing agent (B).
摘要:
Discontinuous coatings and methods of forming such coatings including transiting a substrate through a vaporization area, providing a reactant vapor comprising at least one vaporized monomer or oligomer to the vaporization area, and chemically reacting the at least one vaporized monomer or oligomer to form a discontinuous layer on the substrate, optionally wherein chemically reacting further includes polymerization. The discontinuous layer may be a patterned, semi-patterned, or random discontinuous layer.

Embodiments described herein relate to methods of forming liquid-impregnated surfaces, and in particular to methods of preparing solid particle solutions for forming textured surfaces which can be impregnated with an impregnating liquid to form a liquid-impregnated surface. In some embodiments, a method of forming a textured surface includes dissolving a solid in a solvent to form a solution. The solid has a concentration, which is less than a first saturation concentration of the solid in the solvent at a first temperature and greater than a second saturation concentration of the solid in the solvent at a second temperature. The solution is allowed to form a solid particle solution. The solid particle solution is then disposed on a surface and the solvent is allowed to evaporate to form the textured surface on the surface.
