Hot curing
Principle: By heating, the resin molecules in the resin coating undergo cross-linking reactions, thereby transforming from liquid to solid and achieving the purpose of curing. During the heating process, resin molecules gain sufficient energy, and functional groups with low activity are activated, reacting chemically with each other to form a three-dimensional network of cross-linked structures, improving the hardness, wear resistance, chemical resistance, and other properties of the coating. For example, when the epoxy resin coating is heated to a certain temperature (usually around 120 ℃ -180 ℃, depending on the formula), the epoxy groups react rapidly with the active groups in the curing agent, causing the coating to cure.
Application scenarios and advantages: Widely used in industrial protective coatings, electronic and electrical insulation coatings, and other fields.
UV curing  
Principle: Using specific wavelengths of light (such as ultraviolet UV light, visible light, etc.) to irradiate the resin coating, the photoinitiator in the coating generates active intermediates such as free radicals or cations, which further promote the polymerization and cross-linking reactions of resin molecules, achieving curing. For example, in UV cured acrylic resin coatings, UV light irradiation decomposes the photoinitiator to produce free radicals, which trigger the opening and interconnection of double bonds in the acrylic resin, quickly forming a cross-linked structure and curing the coating in a short period of time.
Wet curing
Principle: By relying on the coating to absorb moisture from the air, a chemical reaction of resin molecules is triggered to achieve curing. This resin coating itself contains functional groups that can react with water, such as isocyanate groups. When it comes into contact with moisture in the air, it undergoes hydrolysis, condensation, and other reactions, generating new chemical bonds such as urea bonds, causing the molecular chains to continuously grow and crosslink, ultimately forming a cured coating. For example, a single component polyurethane resin coating is a typical wet curing type, which gradually transforms from a liquid state to a solid state as it absorbs moisture from the air after coating.
Chemical solidification
Principle: Curing is achieved by adding a curing agent and reacting chemically with the resin. Resin and curing agent each contain functional groups that can react with each other. After mixing, under certain temperature, time, and other conditions, functional groups undergo reactions such as addition and condensation, forming a cross-linked structure and curing the coating. For example, when epoxy resin is mixed with amine curing agents, the epoxy groups and amine groups undergo addition reactions, continuously generating new chemical bonds that gradually crosslink the epoxy resin molecules, ultimately completing the curing of the coating.
