With the rapid development of UV curing technology, divinyl ether, as a high-performance monomer, has become a core raw material in the fields of coatings, inks, adhesives, and nail polish. Shenzhen U-Sunny's VM-3520 product, based on divinyl ether, optimizes the molecular structure and reactivity to provide the industry with efficient and environmentally friendly solutions, helping green manufacturing and product performance upgrades.
1. UV-curing coatings: a balance between environmental protection and performance
Divinyl ether is mainly used as a reactive diluent or cross-linking agent in UV coatings. It achieves rapid curing through photoinduced cationic polymerization, significantly reduces volatile organic compound (VOC) emissions, and complies with environmental protection standards such as EU REACH. The application of VM-3520 can improve coating adhesion, weather resistance and wear resistance. For example, combined with nanomaterials such as fumed silica, VM-3520 can optimize the thixotropy and hydrolysis resistance of coatings, while shortening the drying time by more than 30%. In addition, its low viscosity characteristics support high-pigment content formulations, improve the hiding power and gloss of coatings, and are suitable for high-end scenes such as automobiles and furniture.
2. Ink manufacturing: key technologies for efficient photocuring
In the field of UV inks, VM-3520 achieves instantaneous film formation of inks (within 1 minute) through photocuring reactions, which is particularly suitable for high-precision printing and electronic inks. Its low viscosity characteristics improve ink fluidity and ensure the uniformity of printed patterns. Combined with dispersants, it can enhance pigment stability and reduce the risk of stratification. The high reactivity of VM-3520 also supports the high coloring strength design of thin ink films, reduces the cost of pigment usage, and meets the stringent requirements of packaging printing for scratch resistance and chemical resistance.
III. Adhesives: A two-way breakthrough in greening and high performance
Traditional adhesives rely on solvent-based formulas and have VOC pollution problems. As an active diluent, VM-3520 can reduce the viscosity of the system and reduce the amount of solvent used. At the same time, it can enhance the cohesion and high temperature resistance of the adhesive layer (temperature resistance above 120°C) through cross-linking reactions. In polyurethane or acrylate adhesives, the application of VM-3520 improves the balance between bonding strength and flexibility, and is suitable for precision bonding of automobiles and electronic components. For example, its synergistic effect with polyurethane dispersions can develop environmentally friendly two-component adhesives that meet industrial-grade strength requirements.

IV. Nail polish: Technological innovation in the nail art industry
In UV nail polish, VM-3520 reduces ultraviolet exposure time through rapid light curing (within 1 minute), reduces curing heat release, and improves comfort. Its high purity (≥98%) prevents the nail surface from yellowing, ensures long-lasting and bright colors, and causes less damage to the nails when removing the nail polish. Shenzhen U-Sunny further optimized the formula to make VM-3520 both low-irritation and in line with the safety standards of the beauty industry. It also supports high-toughness design, improves impact resistance by 40%, and extends the life of nail polish.
5. Core advantages and future prospects of VM-3520
Shenzhen U-Sunny's VM-3520 product is centered on technological innovation and has the following advantages:
High-efficiency curing: light/heat dual-mode curing, adapting to complex structural scenes, and improving production efficiency by 30%;
Environmental protection and safety: no benzene solvents, compliant with RoHS and REACH standards;
Multi-scenario adaptation: supports customized formulations of coatings, inks, adhesives, etc. to meet differentiated needs.
In the future, with the advancement of green chemistry and intelligent manufacturing, divinyl ether will be more widely used in the field of photocuring. For example, combined with emerging technologies such as 3D printing and electronic packaging, VM-3520 is expected to promote the transformation of materials science towards efficiency and sustainability.
