A method for forming a multilayer coating film is provided. The method includes coating at least one object with an aqueous primer coating composition, an aqueous first colored coating composition, an aqueous second colored coating composition, and a clear coating composition, in that order. The aqueous primer coating composition contains a component (A) which contains a polyolefin resin, a component (B) which contains a polyurethane resin, a curing agent (C) and electrically conductive carbon (D). The aqueous first colored coating composition and aqueous second colored coating composition each contain a core/shell emulsion. The clear coating composition contains a hydroxyl group-containing acrylic resin, a polyisocyanate and a melamine resin. The method improves the appearance, chipping resistance, adhesive properties and low temperature impact properties of a coating film.

A phosphorus-containing flame retardant, a preparation method thereof, a resin composition comprising the phosphorus-containing flame retardant and an article made therefrom are disclosed. The phosphorus-containing flame retardant is characterized by having the advantages of high phosphorus content, high resin compatibility, not increasing gel time of varnish and low water absorption rate, and is therefore suitable for use as a flame retardant of various resin materials.

A primer composition may include an olefin-based resin (A), and a flaky pigment (B), and satisfy: (1) the primer composition contains a water-immiscible organic solvent, the pigment (B) has an average particle size of?25 ?m and is present in 17+wt. %, based on total primer composition solids; (2) the primer composition contains a water-immiscible organic solvent, the pigment (B) has an average particle size of<25 ?m is present in 42+wt. %, based on total primer composition solids, or (3): the primer composition contains water, the resin (A) is a water-based resin, and a pigment (B) content is 50 wt. % or higher based on total primer composition solids. Such a primer composition can be used in a primer coating film, a layered antifouling coating film, a method for producing a primer coated substrate, or a method for producing a layered antifouling coated substrate.

A transparent, heat-sealable coating for transparent PET packaging foils can be provided by using a heat-sealable lacquer based on styrene-containing copolymers, on poly(meth)acrylates, on at least one polyester and optionally on a tackifier, and also the process for the sealing of a foil coated with this lacquer. It is surprising here that, despite the use of a rubber based on styrene-containing polymers that is not optically compatible with polyesters and polymethacrylate, the transparency of the heat-sealable coatings is still very high.

A method of making a coating applied to an article is provided. The method includes preparing at least one substrate on the article to be coated, to obtain at least one prepared substrate. The method further includes preparing the coating, obtained by disposing a plurality of high density metal pellets in an adhesive material, to form a metal adhesive matrix, and adding a polymer material over the metal adhesive matrix. The plurality of high density metal pellets is in an amount of at least 90% (ninety percent) by weight of the total weight percent of the coating. The method further includes applying the coating to the prepared substrate, to obtain a mass-enhanced, coated article. The coating thickness and the amount of high density metal pellets are sufficient to provide an attenuation of vibration of the coated article and a reduced risk of unwanted ergonomic effects.
