Primer

Primer refers to the paint directly applied to the surface of objects as a solid foundation for finishing paint. It is required to attach firmly on the object surface to increase the adhesion of the upper coating and improve the decorative property of the finish. According to the coating requirements, it can be divided into the first primer, the second primer, etc. The commonly used primers are: 1. Iron red cathodic electrophoretic primer: the paint film has good adhesion and corrosion resistance, which is superior to the anodic electrophoretic primer. It is suitable for the primer of metal parts, especially for steel products. 2. New metal anti-corrosive primer: the paint has fast drying, strong adhesion, good mechanical properties, and good oil resistance, rust prevention and corrosion resistance. It is mainly used for coating the bottom layer of various automobile bodies, carriages and parts. 3. Phosphating primer: used as primer for essence substrate. 4. Amino alkyd second primer: used for intermediate coating. It is applicable to the putty layer that has been coated with primer and polished smooth to fill the sand holes and lines in the putty layer. 5. New wood sealing primer: suitable for wood sealing primer, decoration and architectural paint. 6. New metal primer: used for priming of metal surface. 7. New zinc rich primer: used for underwater metal surface coating and chemical anti-corrosion metal priming in shipyards. 8. Iron red alkyd resin primer: used to coat the steel surface with uniform rust layer. 9. Rubber alkyd primer: brush or spray on the treated metal surface. 10. Zinc yellow polyurethane primer: applicable to the primer coating of railway, bridge and various metal equipment. 11. Acrylic/epoxy resin primer: It has good salt spray resistance, damp heat resistance and good mechanical properties, good adhesion to metal surface, and can be used as an excellent anti rust primer. 12. New polyphenyl oxide precoating primer: used in machinery, vehicles, equipment, shipbuilding and other industries. 13. Epoxy resin colored primer: suitable for coating light metal surface. 14. New asphalt ship bottom paint: it is applicable to the underwater part of ships, and can also be used as the isolation layer between aluminum powder asphalt ship bottom paint and asphalt antifouling paint.

When painting the wall, sometimes we will encounter some small troubles. When painting the wall, the absorption is too fast, and the amount of emulsion paint cannot be applied to the predetermined area; Discoloration occurs soon after painting, and even paint film falls off, lumps and mildew, which often makes us feel helpless. This is because both new and old walls in the room will have alkalization problems due to excessive moisture, especially in humid environments, which is the fundamental reason for affecting the quality of paint. The role of primer is as follows: 1. Sealing: some walls are highly alkaline, and alkali flowers, known as "efflorescence", are produced after being soaked in moisture and water. This situation causes crater like protrusions on the surface of the paint film, and in serious cases, a layer of alkali frost is formed on the surface of the paint film, which eventually destroys the paint film. Latex paint primer can play a sealing role to alleviate this situation. However, if the wall of your house is dry and the floor is high, it may not be a problem, but it is recommended that you use it. It is safe. 2. Adhesion: The content of emulsion in the primer is high, and the adhesion is strong. It can improve the adhesion between latex paint film and wall. 3. Filling: if your wall is not strong alkaline and relatively flat, you can not use primer, which is better. Painting a layer of sealing primer before painting the finishing coat can not only save the decoration cost, but also has the advantage of twice the effort with half the effort in the long run and decoration effect. At the same time, the good adhesion of the primer makes the wall more smooth, makes the finishing coat easier to brush, and reduces the use of the finishing coat. In this way, the wall surface can avoid paint disease and help to maintain the painting effect for a longer time.
In 2008, the overall economic operation quality of China's coating industry has been greatly improved. The market continues to focus on large enterprises and brand enterprises, and the profitability and risk resistance of the industry have been enhanced, showing a benign development trend on the whole. The financial crisis has affected China's real economy. Since the second half of 2008, the adverse situation of demand reduction, production reduction and production contraction in the upstream and downstream of the paint industry has gradually spread, and paint manufacturers have felt the survival crisis brought by the severe economic situation. Faced with the difficult economic situation, the Chinese government has issued a series of support policies, which provide a strong guarantee for stimulating domestic demand and ensuring the smooth operation of the economy. From the published government investment plan, the opportunities related to the coating industry are mainly concentrated in the construction of infrastructure such as transportation, the construction of telecommunications power grid in western China, the post disaster reconstruction of Sichuan disaster areas, and the construction of urban and rural affordable housing. These undoubtedly bring hope for the development of paint enterprises in the "cold winter". After entering 2009, China's paint industry faces four good opportunities for development: rural market; Automotive coatings, household appliances coatings; World Expo and Asian Games; Renovation of old houses. Therefore, the interior wall coating industry has broad growth space.
