Abstract

The invention relates to an electrosilvering-like paint which comprises 10-12 wt% of acrylic resin, 3-6 wt% of filler, 2-3 wt% of pigment, 1.5-3.5 wt% of assistant and 75-85 wt% of solvent. The electrosilvering-like paint provided by the invention has excellent adhesiveness and solvent resistance, and is suitable for application of mobile phones, toys, plastic artware, cosmetics, notebook computer surfaces and the like. The formed paint film has the advantages of flatness, high brightness, bright color, high hardness, high film thickness, favorable wearability, excellent adhesiveness and excellent solvent resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, more specifically, the invention relates to a silver-like coating with excellent adhesion and solvent resistance. Background technique [0002] Acrylic resin-based imitation silver-plating coatings are widely used in the coating of product shells with high chemical resistance because of their excellent physical and mechanical properties, excellent gloss retention, color retention, and weather resistance. For example, the coatings are widely used in mobile phones, Coating on the plastic surface of IT products such as toys, craft plastic products, cosmetics series and notebook computers. When applying the above-mentioned imitation electroplating silver coating, it is usually necessary to first apply a primer coating composition and then perform top coating. Since the applied top coat needs to have an excellent appearance in terms of smoothness and gloss and excellent solvent resistance, it is req...
