A coating film and a method for forming the same are provided. The coating film controls reduction in repellency of hydrophobic fine particles and increases rub fastness of the coating film. The coating film includes a ground layer containing thermoplastic resin (chlorinated polyolefin or acid modified chlorinated polyolefin, for example) and an upper layer containing hydrophobic fine particles (hydrophobic silica particle or silicone resin particle, for example) formed on the ground layer. Parts of the hydrophobic fine particles contained in the upper layer are buried in the ground layer.

Compositions and articles comprising a stress and crack resistant component comprising a thermoplastic component and an elongation component. In some examples, the invention is directed to a stress and crack resistant component comprising a thermoplastic component, an elongation modifier component and an elongation temperer; in preferred examples the thermoplastic component comprises a polyethylene terephthalate glycol-modified (PETG) copolyester, the elongation modifier component comprises a halogenated polyolefin having a heat of fusion of 1 J/g or less, and the elongation temperer comprises a poly(styrene acrylonitrile) (SAN).

In preferred examples the stress-resistant component is comprised as an coating component covering at least one surface of a substrate, such as one comprising a medium density fiberboard (MDF), a particle board, an oriented strand board, fiberglass, a natural wood, a composite wood product, and a synthetic substrate. The stress-resistant component is preferably, though not invariably, produced by extrusion. The invention is also directed to articles, such as extrusion profiles, comprising the stress-resistant component, and methods of making such articles.

An object is to provide a chlorinated polyolefin resin that has excellent solution stability and excellent adhesion to polyolefin substrates including a polyethylene substrate. The chlorinated polyolefin resin is a chlorinated product of a copolymer having a structural unit derived from ethylene, in which a content ratio of the ethylene structural unit in the copolymer is 50 mol % to 90 mol %.

A composite article includes a substrate and a protective coating on at least a portion of the substrate. The protective coating includes reinforcement particles dispersed within an elastomeric matrix that is modified with a silicon-containing modifier selected from polysilsesquioxane, polyhedral oligomeric silicate, polyhedral oligomeric silsesquioxane (POSS), and combinations thereof. The reinforcement particles are selected from carbon, nickel metal, and combinations thereof. The protective coating is multi-layered and includes a distinct first layer and a distinct second layer that is contiguous with the distinct first layer such that each of the distinct first layer and the distinct second layer have an exposed outer surface.
