Application and research of water-print powder coating

 Water-print powder coating, also known as water ripples powder coating, that is, powder coating after coating into a film presents a similar to water-ripple pattern powder coating, is a type of powder coating with strong decorative. China's rich cultural origin, water-print powder coating of the domestic name is different, including water-print, long paint, wrinkles, leather, cloth, mesh, turtle and other well-known powder coating is the most common.
Because the water-print powder coating has a very strong decorative effect, plus water-print powder coating on the product design technology, production and manufacturing equipment process and coating process are required to be higher, plus the cost and price of this powder coating than conventional powder coating is higher, can be used in different environments inside and outside the home, so water-print powder coating is often used as a high-grade high decorative powder coating in the market promotion and application
China

1, water-printed powder coating appearance and effect
fruit water-printed powder coating has a similar effect of water ripples, see Figure 1 to Figure 4 comparison. It can be seen that the water-
powder coating material can be formed with a larger ripple to a smaller sponge effect, with a very rich texture appearance effect. Because the water-print powder coating has a wealth of colors, from black to white, from red to green, from blue to yellow, from dark colors to bright colors can be achieved, see Figure 5 to Figure 8. The water-print powder coating has a shiny luster, a soft luster, or a dull, dry luster. The perfect combination of texture effect, color and gloss enables endless changes to meet the color and texture needs of the finished accessories. Obviously, from bright to antique colors, water-print powder coatings give an almost perfect visual feel.
water-print powder coating appearance, can give people the desired "touch feeling", can be very smooth and delicate, can also be very rough, to meet the needs of product designers for touch. After coating, the water-print powder coating forms a coating film on its surface, which brings people the enjoyment of beauty, but also greatly extends the service life of the product. With the continuous improvement of people's material living standards, the demand for spiritual aspects is getting higher and higher, the product water-print coating gorgeous appearance, bright colors, can make people feel happy.
2, water-print powder coating design and manufacturing technology
water-print powder coating products, like other textured types of powder coatings, are divided into two substation types for domestic applications and common use in the home and outside the environment.
only for in-house applications of water-print powder coating, mainly epoxy resin -dicyanide as the base material, sometimes using a small amount of high-acid polyester resin to adjust the appearance of the product coating effect, production and coating stability, the baking process of the substrate in acetyl acetone aluminum (industry called mian agent or hydrosurgent) catalytic action to form a water-print effect of the coating appearance. In the design of such powder coatings, special attention is not to use those domestic intermediates doped with poor quality epoxy resin, so as not to cause poor product batch stability, coating performance instability. When designing such powder coatings, a small amount of 4/6 polyester resin with an acid value of about 50 mg KOH/g is often used to adjust the appearance and inline performance of the coating, and proper use often has unexpected effects. In particular, epoxy resin-type water-printed powder coating using acetylacetone aluminum catalyst, this catalyst in the process of use will often cause production and operation workers nosebleeds, red eye disease and other harmful to health occupational diseases, serious cases will cause the production workers blind, which in the domestic powder coating manufacturing and coating application industry have found such health and safety accidents. Therefore, in the occupational health more and more attention to today, the harmfulness of this kind of water-print powder coating more and more attention, such acetyl acetone aluminum as a catalyst epoxy-type water-type powder coating will slowly fade out of the application market.
water-based powder coating based on epoxy resin is limited to indoor applications because it does not meet the requirements of the outdoor application environment for product weather resistance and durability. Therefore, can be applied to the outdoor environment to polyester-ammonia resin-type as the main base of the water-print powder coating in high-cost, high-priced man-made control of the situation has not withdrawn from the Chinese market, and as a high-grade powder coating dominant identity has always been in the market. With the successful development, promotion and application of special polyester and methamphetamine products with hydroxyl sealing end, With the further study of such powder coatings by The New School of Commerce, Creamyth®WL32-18A, Creamyth®WL64 -96A, Creamyth®WL52-98A three Teamyth®WL series of products, and with the continued decline in raw material prices, for polyester-ammonia resin-type water-print powder coating in the domestic general promotion and application of the door. Due to the Impact®WL series of amine-enclosed sulfonate catalyst prepared water-print powder coating has environmentally friendly, the production and operation of workers health and safety characteristics, more and more attention to the industry. Polyester-ammonia resin as the main base of the water-print powder coating can form a rich variety of texture effects, with full-color color, with a wide range of gloss regulation, with excellent outdoor weather resistance, so that such water-print powder coating can be applied to a wide range of indoor and outdoor applications and occasions.
Whether it is epoxy-double cyanide as the base of the water-printed powder coating, or polyester-ammonia resin as the base of the water-printed powder coating, product designers have put forward higher design requirements, good product design thinking and experience for product manufacturing and coating applications to bring higher and better production and application stability. In addition, while all powder coating manufacturers can use their original equipment to prepare water-print powder coatings, the same formula, the same raw materials in different powder manufacturers will always get a significant difference in the effect of the water-print coating. Therefore, paying attention to the powder coating preparation process and equipment research will be more conducive to the preparation and application of water-printed powder coating products.
