Abstract

The invention relates to a photocuring finishing paint comprising the following components: 55-65wt% of acrylic resin, 5-10wt% of active monomers, 2-5wt% of initiator, 2.5-4.0wt% of assistant and 20-35wt% of solvent. The photocuring finishing paint provided by the invention has excellent adhesiveness and solvent resistance and is suitable for being used as the finishing paint for IT products such as a television, a motorcycle, an automobile lamp, a mobile phone, a notebook computer and the like. A paint film formed by coating is flat and bright, thick in formed film, high in hardness, good in distinctness of image, high in fullness and excellent in wear resistance and petrol resistance.

Description

Technical field [0001] The invention belongs to the technical field of coatings. More specifically, the invention relates to a light-curing varnish with excellent adhesion and solvent resistance. Background technique [0002] The two-component acrylic polyurethane coatings mainly contain hydroxyl resin and polyurethane as the main film-forming materials. Because of their excellent physical and mechanical capabilities and excellent gloss retention, color retention, and weather resistance, they are widely used in the coating of product shells with high chemical resistance. For example, the thermosetting light-curing varnish can be used in packaging and general industrial coating systems, such as widely used in bicycles, motorcycles, automobiles, refrigerators, washing machines, electric fans, instruments, meters, precision machinery and IT products Surface coating. [0003] When applying the above-mentioned photocurable overcoat, it is usually necessary to first apply the primer com...
