Do you know what is metallic paint? Metal coatings are coatings with metal texture. Most of them need some form of pretreatment on the metal surface to improve the surface condition, so as to improve the adhesion of the coating and enhance the anti-corrosion protection of the metal substrate. UV curable metallic coatings are currently one of the largest application markets. Similar to traditional coating, before metal coating, most of the metal surfaces need some form of pretreatment to improve the surface condition, so as to improve the adhesion of the coating and enhance the anti-corrosion protection of the metal substrate.

introduction to metal coatings

metal coatings are coatings with metal texture. Most of them need some form of pretreatment on the metal surface to improve the surface condition, so as to improve the adhesion of the coating and enhance the anti-corrosion protection of the metal substrate

characteristics of metal coatings

one of the largest application markets of UV curable metal coatings at present is the coating of metal cans. Some two-piece aluminum alloy beverage cans adopt uv/eb coating process. In the coating of food and beverage packaging cans, UV curable or EB curable coatings show strong advantages. Fast curing, low volatility and low odor are the main characteristics of their application in this processing field

types of metal coatings

(1) according to the form of coatings, they can be divided into water-based coatings, solvent based coatings, powder coatings, high solid coatings, etc

(2) according to the construction method, it can be divided into brush coating, spray coating, roller coating, dip coating, electrophoretic coating, etc

(3) according to the construction process, it can be divided into primer, intermediate paint (secondary primer), finish paint, finishing paint, etc

(4) according to function, it can be divided into decorative coatings, anti-corrosion coatings, conductive coatings, Antirust Coatings, high temperature resistant coatings, temperature indicating coatings, heat insulation coatings, fire-proof coatings, waterproof coatings, etc.

(5) according to purpose, it can be divided into architectural coatings, can coatings, automotive coatings, aircraft coatings, household appliance coatings, wood coatings, bridge coatings, plastic coatings, paper coatings, etc

(6) household paint can be divided into interior wall paint, exterior wall paint, wood paint, metal paint and floor paint

(7) according to the performance of the paint film (anticorrosive paint, insulating paint, conductive paint, heat-resistant paint … …)

(8) divided by film-forming substances (alkyd, epoxy, chlorinated rubber, acrylic acid, polyurethane, ethylene … …)

a) according to the type of base material, it can be divided into organic coating, inorganic coating and organic-inorganic composite coating. Due to the different solvents used, organic coatings can be divided into organic solvent based coatings and organic waterborne (including water emulsion and water-soluble) coatings. Common coatings in life are generally organic coatings. Inorganic coating refers to the coating produced with inorganic polymer materials as the base material, including water-soluble silicate system, silica sol system, organosilicon and inorganic polymerization?? Matter system. There are two composite forms of organic-inorganic composite coatings. One is that organic materials and inorganic materials are used as the base material to form composite coatings in the production of coatings; The other is organic paint and inorganic paint in decoration construction?? When combined with each other

b) according to the decoration effect, it can be divided into: 1 Flat and smooth surface coating (commonly known as flat coating), which is the most common construction method; 2. Sand wall paint with sand like decorative effect on the surface, such as genuine stone paint; 3. A multi-layer coating that forms a three-dimensional decorative effect of concave convex patterns, such as relief

c) according to the parts used on the building, it is divided into interior wall coating, exterior wall coating, ground coating and ceiling coating

d) according to the use function, it can be divided into ordinary coatings and special functional building coatings (such as fire-proof coatings, waterproof coatings, mold proof coatings, road marking coatings, etc.)

e) classification according to the color effect: such as metallic paint, transparent varnish, etc

metal coating application

three piece food and beverage tubes made of tinned iron sheet (horse pocket) can also be protected by UV curing coating, or UV glazing after printing ink. The protection of metal copper products tends to be coated with UV varnish rather than paint, which mainly highlights the color and aesthetic texture of metal copper itself. In addition, UV metal coating is widely used in metal sign decoration, metal decorative plate, aluminum alloy door and window protection and steel pipe temporary coating protection. Precoated metal coil is a large market, but there may not be a mass-produced UV coating production line at present. The problems may lie in the rapid curing of low-cost natural color paint, super wear resistance and stamping performance. Many commonly used metals are prone to corrosion, and their surfaces are easy to be stained, affecting their appearance. Metal aluminum, especially aluminum foil or aluminum film deposited on plastic and paper, has soft texture and poor wear resistance and scratch resistance. Aluminum alloy profiles also have similar problems and need coating protection. Similar to traditional coating, before metal coating, most of the metal surfaces need some form of pretreatment to improve the surface condition, so as to improve the adhesion of the coating and enhance the anti-corrosion protection of the metal substrate
