Abstract

The two-component finish paint includes component A and component B. The component A is mainly hydroxy bisphenol propane and epoxy chloropropane synthesized resin; and the component B is isocyanate and diaminotoluene affixture. The present invention also relates to the production process and usage of the paint product. When the finish paint is used, the two components are mixed and the finish paint is cured via crosslinking of hydroxy group and isocyanate to reach natural drying at normal temperature. The paint product of the present invention has great adhesion force, good toughness, good antifouling performance, high wear resistance, salty fog resistance, gasoline resistance, acid and alkali resistance, high electric insulating performance, shock resistance, heat resistance, cold resistance and good fireproof performance. It is used as finish paint widely in different fields.

Description

technical field [0001] The present invention relates to a two-component paint product, a method for its production and a method for its use, especially a paint product for topcoats based on epoxy resins. Background technique [0002] Paint refers to a type of film-forming substance that can dry and form a film when applied to the surface of an object, making the object beautiful and protected, or forming a film with other special functions on the surface of the object. Paint is a multi-component system, generally a viscous liquid. Since the function of paint is to protect different surfaces and environments, it needs to have mechanical strength, aging resistance, and corrosion resistance. [0003] The film-forming substances of paints mostly use high-molecular compounds, which are generally called resins for coatings. They should have the following properties: good solubility, good miscibility, good film-forming properties and wettability to pigments, and can impart certain ...
