Types of metallic paint, what are the types of metallic paint?
As we all know, coatings are widely used in life, almost in all fields. Metallic paint is also a kind of paint, the use rate is very high, and there are many types of metallic paint, all of which have different functions. In order to give you a specific understanding of metallic paint, let me introduce you to what types of metallic paint are.
Types of metallic paints
1. Metal anti-rust coatings
Metallic paint is usually used as metal anti-rust paint, but also has some decorative functions, the main components are anti-rust pigments and film-forming substances. It is usually named after the name of anti-rust pigments, such as: red anti-rust paint, iron red anti-rust paint, etc. If it is distinguished by the anti-rust mechanism, it can be roughly summarized into four types: physical anti-rust paint, chemical anti-rust paint, electrochemical anti-rust paint and comprehensive anti-rust paint.
Some of the commonly used metal antirust coatings have the following functions:
1. Zinc yellow anti-rust paint: made by adding zinc chromium yellow pigment with pure phenolic paint and grinding and modulating. It has strong adhesion and high resistance to the marine environment.
2. Iron red alkyd antirust paint: It is made by adding alkyd paint, filler, solvent and drier to pigments such as iron dan, lead chrome yellow, etc. Good adhesion, strong rust resistance, high hardness, elasticity, and strong impact and nitro resistance.
3. Gray anti-rust paint: It is made by adding varnish with lead-containing zinc oxide as the main anti-rust pigment. It has excellent properties against rust and atmospheric erosion, but dries more slowly. Suitable for painting exterior steel elements.
4. Iron red phenolic antirust paint: It is made of dry vegetable oil modified phenolic resin and iron red, anti-rust pigment, physique pigment, etc. after grinding, adding driers, and modulating with No. 200 paint solvent oil and xylene. It has good adhesion and certain anti-rust properties, and has good adhesion to nitro, alkyd and other topcoats.
5. Hongdan anti-rust paint: This is a kind of paint made by mixing red dan with dry oil. It has good permeability and wettability, and the paint film is soft and adherent, but it dries slowly. In addition, due to the large proportion of red dan, it is easy to precipitate, and it will become thicker if stored for too long, and the brushability is also poor.
Second, special automotive metal paint
Metallic paint also has a definition of paint with metal powder added to the paint, which is a commonly used paint for automobile painting. The most important application area for metallic paints is the automotive industry. The exterior surface of a car painted with metallic paint not only looks more sparkling, but also changes the color and even the silhouette of the car at different angles due to the refraction of light.
Metallic paints are generally available in two types: waterborne and solvent-based. Water-based paint has good environmental protection, but the metal powder is unstable in water and air, and often deteriorates due to chemical reaction, so its surface needs special treatment. At present, metallic paints are mainly solvent-based, and according to the different paint-based resins, solvent-based metallic paints include acrylic metallic paints, fluorocarbon metallic paints, etc.
The shadow of metallic paint can be found in our common fitness equipment, street lamp poles, vehicle surfaces, etc., and it can be said that metallic paint is inseparable from us. Due to the needs of the working environment and decorative effects, there are also different types of metallic paint, and interested friends can also learn more about it.
