Coating curing, a necessary process in the coating construction process, refers to the process by which the coating is applied to the object to be coated and a dry coating film (including hard and soft film) is formed by various means. There are various coating curing methods, and it is very important to choose the appropriate curing method according to different coating types and application scenarios. Next, I will share with you the four commonly used coating curing methods.
1、Natural curing
Natural conditions, the use of air convection so that the solvent evaporation, oxidation polymerization or reaction with the curing agent to form a film, applicable to volatile coatings, air-drying coatings and curing agent curing coatings and other self-drying coatings, drying quality by the environmental conditions have a great impact.
➀ Solvent Volatilization Curing
It is the solvent volatilization through the surface of the coating, leaving the solids of the coating and being attached to the surface of the coated material to form a dry solid coating film.
➁ Air Oxidation Curing
It is the use of oxygen in the air to make the coating dry film, the oxygen in the air and the coating crosslinking reaction to form a dry film.
➂ Thermal or Chemical Cure
This kind of coating in the heating or in the catalyst (including assimilating agent) under the action of chemical cross-linking reaction, coating in a variety of film-forming components fused with each other, crosslinked to form a three-dimensional mesh structure of the coating film.
2、Traditional heating curing
Drying according to the drying temperature can be divided into low-temperature drying (less than 100 ℃, mainly for self-drying coatings or poor heat-resistant material surface coating drying). Medium temperature drying (100-150 ℃, mainly used for condensation polymerization reaction curing film coatings). High temperature drying (higher than 150 ℃, mainly used for powder coatings, electrophoretic coatings, etc.).
➀ Combined hot-air convection plus radiation curing
Generally the first radiation after convection, the use of radiation heating the advantages of fast, so that the workpiece heating, and then use the hot air convection insulation, to ensure the quality of drying.
➁ Hot-air convection curing
Hot air convection heating uniformity, high temperature control, suitable for high-quality coatings, not affected by the shape of the workpiece and the complexity of the structure, but slower heating speed, lower thermal efficiency, equipment is huge, the coating is easy to blistering, wrinkles, high dust requirements. The heat source used is steam, electricity, diesel, gas, liquefied petroleum gas and natural gas.
➂ Melt curing
Melt-cured coatings generally refer to solid powder type coating products.
3、Radiation curing
➀ Ultraviolet (UV) radiation curing
Is a kind of energy irradiation with the help of chemical formulations (coatings, inks and adhesives) from liquid to solid process.
➁ Near Infrared Curing (Short Wave Infrared)
Near-infrared technology enables powder coatings to work and cure quickly within seconds.
➂ Infrared (longwave, midwave) radiation curing
Usually use infrared, far-infrared radiation to the object directly after absorption into heat energy, so that the coating curing.
➃ Infrared catalyzed thermal reaction curing
Is to use the coating itself to absorb infrared energy into thermal energy to make the coating film curing method.
➄ Microwave Curing
Microwave refers to the frequency of 0.3 ~ 300GHz electromagnetic waves. Materials in the microwave effect will produce heating, melting and other physical phenomena, but also chemical reactions.
4、Other special curing
➀ Electron beam curing
English name electron beam curing, is the use of electron gas pedal generated high-energy electron beams as a radiation source, inducing liquid oligomers through crosslinking polymerization and rapid formation of solid products.
Ammonia Vapor Curing
Ammonia steam curing is a special drying method designed for ammonia curing coatings.
➂ Induced Heat Cure
It is another new technology of fast curing. It is heated by exposing the metal substrate to a variable electric field.
In summary, coating curing methods mainly include natural curing, heat curing and UV curing. For different types of coatings and application scenarios, it is important to choose the appropriate curing method to ensure the excellent performance and service life of the coating. Therefore, in the process of coating selection and construction, the characteristics and requirements of the curing method must be fully considered in order to realize the ideal coating film effect.
