紫外光固化聚氨酯涂料 - Introduction
UV-curable polyurethane coatings are coatings that are cured by UV-induced polymerization. It has the following characteristics:
1. Fast curing: UV light can initiate polymerization reaction in a few seconds to a few minutes, so that the coating can be cured quickly and the production speed can be accelerated.
2. Highly wear-resistant: UV-curable polyurethane coatings have good wear resistance and scratch resistance, and can provide long-term protection and decorative effects.
3. Good chemical resistance: This coating has good resistance to some chemicals and can resist the erosion of some solvents and chemicals.
4. Excellent gloss: UV-curable polyurethane coatings can provide a high degree of gloss and transparency, making the coating have an excellent appearance.
5. Environmental protection: UV-curable polyurethane coatings usually do not contain organic solvents, have a low volatile organic compound (VOC) content, and are environmentally friendly.
UV-curable polyurethane coatings are used in a wide range of applications, such as furniture, woodworking, auto parts, electronics and packaging. Its Main uses include providing surface protection, enhancing decorative effects, improving wear resistance, providing protective layers, etc.
The preparation of UV-curable polyurethane coatings requires polymer prepolymers, reactive monomers, initiators and additives. It is often desirable to cure by mixing the ingredients and then exposing the mixture to ultraviolet light to trigger polymerization.
When using UV-curable polyurethane coatings, you need to pay attention to the following safety information:
1. Avoid direct contact with skin or eyes, and wear personal protective equipment, such as gloves and goggles.
2. Use in a well-ventilated place to avoid inhaling volatile organic compounds.
3. UV-curable coatings may cause allergic reactions to certain people, so allergy testing should be performed before use.
4. Pay attention to the storage of paint, avoid direct sunlight or high temperature environment.
5. Comply with the guidelines for the safe use of coatings and the regulations on waste disposal.
