Compared to general solvent-based coatings, the characteristics of UV coatings are as follows:
1. Fast curing speed
UV coatings are cured under UV photon irradiation (UV UV lamps), usually in about 1 second or less, allowing rapid continuous operation and greatly increasing production efficiency.
2. Normal temperature curing
Oligomers commonly used in UV coatings, such as epoxy acrylate, urethane acrylate, polyester acrylate, polyether acrylate, acrylate polyacrylic resin, unsaturated polyester, and various acrylate monofunctional groups Or polyfunctional monomers, which can initiate room temperature polymerization and cross-link by free radical photons under the action of ultraviolet photons, thus being particularly advantageous for the coating of heat-sensitive substrates such as wood, paper, and plastic.
3. Saving energy
UV coatings do not require heat drying, which saves energy by 75% to 90% compared to conventional hot dry coatings during construction.
4. Does not pollute the environment
UV coating is a solvent-free or solvent-free coating. VOC is volatilized into the atmosphere during film formation, and it does not pollute the environment. It is easy to meet the environmental regulations of the government or the legislature.
5. Improve product performance
The UV coating realizes the cross-linking polymerization between the components under the action of ultraviolet photons, rapidly solidifies the liquid into a film, and has a three-dimensional network structure, thereby improving the surface properties of the paint film, such as hardness, flexibility, and abrasion resistance. Scratch resistance, chemical resistance, high gloss, durability, etc.
