The invention relates to paint, in particular to waterborne metal flashing paint and a preparation method thereof. The invention particularly relates to waterborne acrylic resin metal flashing paint which has a core-shell structure containing a chelation group, and is particularly applicable to automotive coatings. The flashing paint combines the advantages of the core-shell structure and an acetyl acetoxyl functional group, so that the disadvantage of high volatile organic compound (VOC) emission of the conventional solvent-based metal flashing paint is overcome; the sagging resistance, solid content and metal flashing property are improved; and the metal flashing paint is well matched with overcoat varnish.

The invention provides an automobile anticorrosive coating with a self-recovery function and application thereof and belongs to the field of automobile anticorrosive materials. In the automobile anticorrosive coating, self-recovery microcapsules are uniformly dispersed between an intermediate coat and a primer of an automobile coating so as to form the anticorrosive coating, of which the structure is similar to a sandwidge structure. Microcracks can be easily formed in the automobile coating due to influence of factors such as physical impact, temperature change, aging and the like on the automobile coating during long-time use; the self-recovery microcapsules embedded in the coating are damaged by an outer force; released core materials can directly generate crosslinking polymerization reaction with oxygen in the air without catalyst so as to recover the microcracks to prevent further corrosion on the metallic surface; and the automobile anticorrosive coating can be widely applied to self-recovery of automobile industrial anticorrosive coatings.

A method and system are provided for dispensing a colored polymerizing composition. Two reactive components and one color component are pumped from respective containers at a metered volume. The color component, which is preferably a low-viscosity automotive paint is injected into either the first or second stream of reactive component at a point immediately prior to mixing all components in a dispensing device for dispensing the resulting colored fluid mixture onto a surface to be coated. The mixture may be dispensed by pouring or spraying onto the surface. The method and system are particularly useful for mixing and dispensing colored polyurethane or polyurea coatings, such as for spray-on truck bed liners.

The present invention is directed to a monitoring device used for producing a target composition, such as an automotive paint or an architectural paint and a monitoring device used therein.

The invention relates to water dispersible environmentally-friendly nanometer structure automotive finish paint and a preparation method thereof and belongs to the technical field of production of coating. The finish paint consists of water dispersible nanometer polymer emulsion with a grain size of below 100 nanometers, deionized water, a pigment, an inert antirust pigment, an active antirust pigment, a filler, an aid and the like. The water dispersible nanometer polymer emulsion with a grain size of below 100 nanometers consists of hydrophilic acrylate copolymer, hydrophobic polymer, waterproof liquid and deionized water, wherein the hydrophobic polymer is one of polyurethane, unsaturated fatty acid or dry oil-improved polyurethane. The invention has the beneficial effects that the water dispersible environmentally-friendly nanometer structure automotive finish paint has the characteristics of safety, environment friendliness and innocuity; and meanwhile, a formed paint film is very compact, and the water resistance and the protection and decoration effect of formed paint film achieve or exceed those of traditional oily automotive finish paint. The water-dispersible environmentally-friendly nanometer structure automotive finish paint is widely applied to waterborne automotive coating as well as the coating industry, thereby having great application value and market prospect.

The present invention relates to a weldable pre-primed coating composition, comprising binder resins, a crosslinker, an anti-corrosive pigment, conductive metal powder, carbon nanotubes, etc. The coating composition can be applied to a metal sheet before processing of the metal sheet to maximize the weldability, adhesion, corrosion resistance and processability of the metal sheet. Also, the coating composition can be applied to a metal sheet by a roll coating process to make it possible to eliminate not only an existing electrodeposition process which is carried out by a non-environmentally-friendly wet dipping process, but also an existing electrostatic spray primer coating process which is carried out by an electrostatic spray coating process in which a solvent is scattered, whereby the metal sheet coated with the coating composition has very excellent formability and weldability after its processing. Accordingly, the composition makes it possible to reduce the number of complex automotive coating processes, thereby greatly contributing an increase in productivity, a reduction in energy and an improvement in a work environment.
