Like all coatings in aircraft skin coating barrel, its composition is divided into film resin, pigments and fillers, solvents and additives. 1. Film forming resin The film forming resin of aircraft skin coating has gone through several generations of updates. The oil-based resin coating is the first generation, the alkyd resin coating is the second generation, the pure synthetic resin such as polyester, polyamide, epoxy, acrylic acid, polyurethane and other resins is the third generation, and the organic silicon, organic fluorine resin and its modified products are the fourth generation. 2. Pigments, fillers, pigments and fillers include pigments and fillers for coloring, rust prevention, temperature resistance, etc. The selection requirements are the same as those of ordinary coatings, which are special requirements applicable to some special parts of the aircraft, such as night hair

Electrostatic conductive coating is a kind of coating applied on the object to prevent electrostatic generation. It can also prevent dust, corrosion, rust and other functions. This article mainly introduces the electrostatic conductive coating. The performance and use method of electrostatic conductive coating will not produce static electricity or conduct static electricity to a safe place in some way after coating. The effect of electrostatic conductive coating is that no open fire is generated in the flammable place. Spraying and brushing can be used to operate on the surface of electronic appliances, detection boards, etc., protect various mechanical products, etc. The electrostatic resistance of electrostatic conductive coatings can reach 5-11 power of 10 at a time, so that the use and

Since the development of the paint and coating industry, additive thinking has always been used in product innovation, which is a process that the industry must go through from its initial stage to its maturity. However, apparently driven by impetuous eagerness for quick success and instant benefit, some enterprises have gone too far in the application of addition, so that the product innovation phenomenon of conceptualization, literalization, and no change of dressing has become popular. The pure additive product innovation thinking has been in the industry for nearly ten years, which not only limits our thinking, let us take it for granted that we deviate from the direction of product innovation and go astray, but also indirectly hurt the healthy growth of most enterprises and brands. Product innovation thinking is based on

The antirust performance of water-based coatings was not as ideal as expected after use, so we analyzed the reasons for the coatings. Starting from the conventional salt spray resistance of the paint film<200h, we conducted a paint film rust prevention test on steel plates that meet the manual rust removal standard. The paper is divided into three parts: one part is mainly to characterize and analyze the rust layer and rust converter A involved in the rusty antirust coating through infrared spectrum, scanning electron microscope, gas chromatography-mass spectrometry and other characterization methods, The results show that the main composition of the rust layer is flake Fe3O4 from the inside to the outside, then rod like γ - FeooH and dot like α - Feoo

The waterborne epoxy zinc rich primer is prepared by a certain process with waterborne epoxy resin system as the binder, pigments, fillers and additives. The diluent of waterborne epoxy paint is water, which is an environmentally friendly epoxy paint. This paint can be used as the primer or intermediate paint for water-based anti-corrosion coating, and can be used as the antirust primer or intermediate paint for steel, aluminum, galvanized steel and metal sprayed coating surface on the waterline. 1. The physical, chemical and mechanical properties of the coating are good; 2. It is not flammable or explosive, and is convenient for transportation. 3. Dilute with tap water, and clean construction tools, equipment and containers with tap water, greatly reducing the coating cost. 4. Can form firm

It is believed that everyone will not be unfamiliar with the color steel tile paint, which is mainly applied to the color steel tile, playing the role of weather resistance, strong adhesion, and long service life. However, if you do not know the correct painting, it will often affect the use time of the color steel tile paint. 1. Base material treatment The treatment of base material is an easily ignored problem in painting, and improper treatment will directly reduce the use time of the coating, so the treatment of base material is very important to avoid the formation of uneven paint film after painting, which will seriously affect the adhesion of the coating, and will affect the overall use time, thereby reducing its

We cannot be blindly optimistic about the "hand to hand" war between the emerging environment-friendly paint and the traditional epoxy polyurethane metal anti-corrosion paint, which reminds enterprises that the way out is to actively adjust production capacity and change the business mode, and the ultra-fine powder metal in the coating forms a dense interface transition layer in the coating. Improve the scientific research strength, and the traditional paint industry is still "ambitious" to occupy a certain chemical market pattern. Continue to adhere to structural adjustment, transformation and upgrading to prevent condensation water pitting corrosion and stress corrosion. According to incomplete statistics, continue to work hard to make the epoxy polyurethane metal anti-corrosion paint coating have high thermal shock resistance, and help the anti-corrosion paint coating form a

Now it is thought that epoxy resin can be used regardless of its function and workability conditions, so most people choose to buy epoxy coatings. In fact, you can also look at other types of coatings. For example, chlorinated rubber paint, a single component, it does not need to add curing agent, and it is easy to mix, and it has a wide range of adaptability and application. Chlorinated rubber finish characteristics: the paint film dries rapidly. Low temperature environment and high temperature environment (- 20 ℃~50 ℃) can be used for normal construction. Of course, construction should not be carried out in the environment beyond the temperature range. The coating can tolerate people. The coating has strong adhesion and will not appear empty drum and interlayer
