[ Coatings for notebook computers ]

Since 2005, notebook production has exploded in China, and today it is moving towards a market share of one person. At first, the notebook coating was mainly made of two-component PU paint as the primer, and the two-component PU topcoat was covered. With the development of UV coating technology, the UV performance was greatly improved. UV coatings are being adjusted to UV coatings at a rapid rate due to their hardness, abrasion resistance and chemical resistance. Notebook UV coatings are concentrated in Shanghai Songjiang and Kunshan areas, among which Large notebook processing units include Foxconn, Quanta Group, Compal Group and Shengmei.

Today's notebook cover substrates are mainly PC (polycarbonate) and PC + ABS (polycarbonate and ABS mixture), and a small part is ABS (acrylonitrile-butadiene-styrene).

Notebook UV coating, generally on the surface of the substrate first thermoplastic acrylic paint or two-component PU paint, followed by UV cover light, the current color paint bottom is black and silver as the mainstream, for the magnesium alloy part of the coating Both the primer and the topcoat are made of a high-temperature baking type coating, and some of them are first plated on the ground before being coated with a paint.

Notebook UV performance requirements vary according to different quality requirements. The basic requirements are: adhesion, leveling, hardness, gloss, high and low temperature cycle test, crack resistance, high temperature and humidity resistance, wear resistance (RCA) , scratch resistance, chemical resistance, salt spray resistance, etc. The main performance requirements are adhesion, leveling, high and low temperature resistance and wear resistance. At present, the notebook UV varnish formula design is mainly used to find the balance between hardness and high and low temperature ring test under high film thickness (generally larger than 30 microns). At present, for new high-end notebook varieties, fingerprint resistance, water resistance and other new products are proposed. Claim.
