Bifunctional Monomer for Adhesives and Inks: Shenzhen U-Sunny VM-3520's innovative solutions in multiple fields

May 16, 2025 Leave a message

In the coating, ink, adhesive and nail polish industries, bifunctional monomers are becoming the core raw materials to promote technological innovation due to their unique chemical structure and high reactivity. Shenzhen U-Sunny's VM-3520 product combines environmental protection, high efficiency and multifunctionality through the optimized design of bifunctional monomers, providing high-performance solutions for global customers.

 

1. Technical advantages of bifunctional monomers
The bifunctional monomer molecule contains two reactive functional groups (such as acrylate and vinyl ether) at the same time, which enables it to act as a crosslinker, diluent or toughening agent in a light-curing or heat-curing system, significantly improving the mechanical properties and chemical stability of the material. For example:

Fast curing: Through photo-initiated free radical or cationic polymerization, the curing time is shortened to within 1 minute, and the production efficiency is increased by more than 30%.

Environmental protection and safety: Reduce the use of solvents, reduce VOC emissions, and comply with EU REACH and RoHS standards.

Multi-scenario adaptation: Customizable formulas to meet the needs of different industries such as coatings, inks, and adhesives.

2. Adhesive industry: Breakthroughs in greening and high performance
Traditional solvent-based adhesives have VOC pollution problems, and VM-3520 bifunctional monomers promote innovation in the following ways:

Reduced viscosity: As an active diluent, it reduces the amount of solvent used while enhancing the flexibility and cohesion of the adhesive layer.

High temperature resistance: The cross-linked structure makes the adhesive temperature resistant to more than 120°C, which is suitable for automotive electronic packaging and high-temperature industrial scenarios.

Environmental certification: Shenzhen U-Sunny's VM-3520 does not contain benzene solvents, passed SGS heavy metal and skin irritation tests, and is in line with the trend of green manufacturing.

 

 

3. Ink manufacturing: efficient photocuring and improved printing accuracy
In UV ink, VM-3520 achieves the following innovations through the synergistic effect of dual functional groups:

Rapid film formation: Photocuring efficiency is increased by 30%, supporting high-precision printing (such as PCB circuit board character printing), ensuring pattern uniformity and scratch resistance.

Low viscosity design: Optimize ink fluidity, reduce stratification risks, and is suitable for flexible packaging and electronic inks.

Color stability: Highly compatible with pigments and resins, extending the storage life of inks and maintaining bright colors.

 

 

4. Nail polish industry: dual upgrade of safety and durability
The application of VM-3520 in UV nail polish solves the health risks and performance shortcomings of traditional products:

Low irritation: Abandon harmful ingredients such as HEMA and TPO, and use high-purity resin raw materials (≥98%) to avoid yellowing of the nail surface.

Fast curing: Complete light curing within 1 minute, reduce UV exposure time, and reduce the risk of nail damage.

Anti-sedimentation design: Combined with the three-dimensional mesh structure of fumed silica, it prevents sequins from settling and sagging, and extends the life of nail art.

 

5. Optimization of weather resistance and environmental protection in the field of coatings
VM-3520 performs well in industrial coatings:

High adhesion: Closely combined with metal and plastic substrates, suitable for automotive and aviation coatings.

Improved weather resistance: Hydrolysis resistance and anti-yellowing properties extend the service life of the coating, especially for outdoor extreme environments.

Low shrinkage: The curing shrinkage is less than 2%, ensuring that the coating is flat and crack-free, suitable for 3D printing and precision electronic equipment.

 

 

Core competitiveness and future prospects of VM-3520
Shenzhen U-Sunny's VM-3520 product is centered on technological innovation and has the following advantages:

Efficient dual-mode curing: Supports light/heat dual curing to adapt to complex process requirements;

Compatible with the entire industry chain: From coatings to nail glue, covering multiple industry application scenarios;

Sustainable development: In line with the global green chemistry trend, helping customers achieve carbon reduction goals.

With the popularization of UV curing technology and the rise of bio-based materials, dual-functional monomers have broad application prospects in smart manufacturing, electronic packaging and other fields. Through continuous research and development, Shenzhen U-Sunny will promote VM-3520 to become a global benchmark for high-performance chemical raw materials.
