In the field of fine chemicals, Triethylene Glycol Divinyl Ether (CAS 765-12-8) has become the core raw material for technological upgrades in the coatings, inks, adhesives and nail art industries due to its unique bifunctional monomer properties. As the core component of Shenzhen U-Sunny's VM-3520 product, this compound is leading the industry to transform towards high efficiency and greenness with its high reactivity, environmental protection characteristics and multi-scenario applicability.
1. Coatings industry: Double breakthrough in environmental protection and performance
Triethylene glycol divinyl ether is mainly used as a crosslinker or reactive diluent in coatings, which significantly improves the adhesion, weather resistance and hydrolysis resistance of coatings. The vinyl ether group in its molecule can be rapidly polymerized by light or heat initiation, greatly reducing the volatile organic compound (VOC) emissions of traditional solvent-based coatings, and complying with environmental protection standards such as EU REACH. For example, in waterborne polyurethane coatings, the introduction of VM-3520 can shorten the drying time by more than 30%, while enhancing the glossiness and anti-yellowing ability of the coating film.
2. Ink manufacturing: Promoter of efficient photocuring technology
In the field of UV curing inks, this monomer achieves instant curing of inks (within 1 minute) through photoinduced cationic polymerization, which is particularly suitable for high-precision printing and electronic inks. Its low viscosity characteristics (density 0.99 g/mL) optimize the fluidity of the ink and ensure the uniformity and fineness of the printed pattern. In addition, the high compatibility of VM-3520 with resins and pigments reduces the risk of stratification and improves the stability and color vividness of the ink.
3. Adhesives: Balance of flexibility and strength
As an active diluent, triethylene glycol divinyl ether effectively reduces the viscosity of the system and the amount of solvent in polyurethane adhesives, while enhancing the cohesion and high temperature resistance of the adhesive through cross-linking reactions (temperature resistance of more than 120°C). Studies have shown that its application in automotive adhesives and packaging materials can increase the bonding strength by 20%-30%, while maintaining flexibility and avoiding brittle cracking.
4. Nail polish: the innovative force of the nail industry
In UV nail polish, this monomer is the key component to accelerate the light curing process, reduce the UV exposure time to 1 minute, reduce the heat release during curing, and improve the comfort of use. Its high purity (≥98%) prevents the nail surface from yellowing, ensures long-lasting and bright colors, and causes less damage to the original nails when removing nail polish. Shenzhen U-Sunny's VM-3520 product further optimizes the formula, making the nail polish both fast curing and low irritation, meeting the safety standards of the beauty industry.
5. Core advantages of VM-3520 products
VM-3520 triethylene glycol divinyl ether launched by Shenzhen U-Sunny is known for its high purity (≥98%) and low impurities. It is designed for industrial applications. Its technical highlights include:
