Application of elastic resin elastic feel coating on the outer surface of the enclosure

China Paint Online News Information
Now the appearance of daily necessities more and more demanding effects, such as aluminum powder effect, crack effect, elastic feel effect and so on, especially some often touch the part by hand, requires the spraying of elastic hand paint, such as blower handle, MP3 shell, mouse, mobile phone shell, telescope, umbrella handle and so on, make people feel a soft and smooth feeling, for this elastic hand paint. Elastic hand coating, also known as rubber coating, is now mainly a two-part solvent-based products: a group is a straight-chain polyester resin with hydroxyl or a modified polyester resin with hydroxyl with a small branch chain; The other group is isocyanate-type curing agent, generally with HDI trimer type or reduced diuretic type. Solvent-based single-part coatings, UV-cured coatings, water-based coatings, due to its performance and price problems, less applications in the Chinese market.elastic hand coating is mainly composed of elastic resin, curing agent, drying agent, anti-light powder, elastic powder, hand aid, organic solvent and so on.most commonly used elastic resins are hydroxyl straight-chain polyester resins, and the other is polyurethane resins with polyurethane elastomer-modified. Compared with the two types of resin products, pure straight-chain polyester resin is cheap, cost-effective, while modified polyester resin price is relatively high, but in some major properties (such as feel, scratch resistance) more than pure polyester resin.Elastic feel coating application and precautions with the formula produced elastic feel paint is particularly suitable for more sensitive plastic materials, all kinds of plastic materials are very good adhesion, have good anti-sinking, good job performance, spraying paint and dust conditions are not obvious; Is a slow-drying type of paint, with baking suitable for mass production. It should be noted that the elastic feel paint drying quickly, must cover the finished barrel cover from time to time, and ensure that the construction process without moisture penetration; In addition, if the surface of the coating lumps, do not break the lumps, must use a thick filter to filter out the lumps; After each spray production must be cleaned equipment, you can choose to use matching thinner to clean the equipment; If the spraying equipment previously used other types of paint, before spraying the elastic feel paint, the spraying equipment should be flushed clean with the matching thinner of the elastic hand coating; After mixing with the curing agent, it must be used up within 6 h; The spraying environment must be clean and well ventilated, otherwise the coating surface will be stained with dust particles.
