Application and Development of fluorine resin


Department) PVDF is a crystalline polymer, so far FEVE fluorine resin coating system is not soluble in common solvents, difficult to control the temperature baking, and baked at high temperature strength decreased and the deformation of the substrate, coating gloss at 40 below, so the application is limited. Asahi Glass Company and the East Asia co-developed cross-linking solvent soluble fluorine resin coating, which can be dissolved in the general aromatic hydrocarbons, esters, ketones commonly used solvents. This coating has the following excellent features: (1) Super weather resistance; (2) curing characteristics of a good; (3) coating of good construction; (4) beautiful appearance; (5) re-coating adhesion is good. This coating suitable for various purposes, various methods can be coated on different substrates, and expand the applications of fluorine resin. Page 18 3.2.3 fluorine resin powder coatings powder coatings for its completely free of solvents, can all be converted film and coating efficiency, protect the decoration and good overall performance, meet the paint industry on resource conservation, energy to reduce environmental pollution and improve the effectiveness requirements. Since the powder coating this unique economic and social benefits, it attracted worldwide attention, and get rapid development. As the world of powder coatings market continues to expand,[link widoczny dla zalogowanych], in order to meet different requirements, not only the production of powder coatings continues to improve, but the variety of powder coatings are also constantly updated, in particular high performance powder coatings and promotion of research and development application is in full swing. Following is a brief introduction of thermoplastic, thermosetting fluorinated resin powder coatings r] Department of thermosetting fluorine resin powder should have the following characteristics: (1) coatings: solvent, in powder form, color, excellent dispersion, transparency storage stability. (2) coating: the subject to seasonal restrictions, and can be 100% recycled; has a very strong acid rain resistance, ozone and UV linear; adhesion, high gloss. Department of thermosetting fluorine resin powder coatings gloss retention, low temperature, durability, powder coating systems than epoxy and polyester resin and acrylic resin powder coating line powder coating system to be good, even with fluorine resin system solvent Paint comparable. For the fluorinated resin powder coating FEP, PFA, ETFE, ECTFE and PVDF, etc. These resins are of fluorine-containing thermoplastic resin. Although they both have excellent weathering resistance and chemical resistance, but because of its film-forming temperature is higher, requiring high-temperature baking, making it difficult (on the next page 16) that the performance is superb coating, the construction is simple. Construction of high solid coatings and solvent-based paint is basically the same, the original coating line need not be a big transformation can be used. High solid coatings with low viscosity,[link widoczny dla zalogowanych], polyester, acrylic resin and amino resin of high solid, solid construction of the highest points can be greater than 60%, the average practical. Application of fluoride village-style music show Grease 4. Fluorine resin development proposals will be the focus of development in China Fluorine Chemical is an important class of synthetic resin. In the development of the production of fluorine resin,[link widoczny dla zalogowanych], not only to consider the scale,[link widoczny dla zalogowanych], improve economic efficiency and market competitiveness, should also address issues related to waste. State ~ PTFE more complete variety of products, but more versatile products, super size, super-small size of fine products and special purpose products less. Recommended the development of fluorine resin,[link widoczny dla zalogowanych], polyolefin resin copolymer with other products and mixed products, open up the application. Should now pay attention to the development of PVDF, FED, etc. to meet the automotive, electronics, petrochemical, and other area; adjustment of product structure development of fine-grained suspension PTFE resin dispersion resin and concentrated dispersions, and further develop the market.
