Diethylene glycol divinyl ether CAS 764-99-8
Diethylene glycol divinyl ether is a colorless transparent liquid with a molecular formula of C8H14O3 and a molecular weight of 158.2. Diethylene glycol divinyl ether belongs to the class of diluents. Low viscosity, with two ethylene ether active double bonds, it is the main component of the cationic UV curing system. It is a classic active diluent and crosslinking agent in the UV industry; it is slightly soluble in water and can be miscible with alcohols, esters, aromatic hydrocarbons, and ethers.
We are the manufacturer of diethylene glycol divinyl ether with CAS number 764-99-8. The regular purity is GC ≥ 98%/99%. The acid value, moisture content, and content of anti-aging agent are controllable, and the batches are stable.

Application
Diethylene glycol divinyl ether is mainly used for the synthesis of intermediate ethers in materials.
1. UV cationic coatings: protective topcoats for wood, plastic, and metal, release coatings; reduce viscosity of the system, accelerate curing, enhance flexibility and chemical resistance of the film layer.
2. UV inks: screen printing, inkjet printing, printing oil ink activators, suitable for high-speed printing lines.
3. UV adhesives & sealants: crosslinking monomers for UV-curable adhesives, active diluent components.
4. Resin synthesis: acrylic ion-exchange resin crosslinking agent, hydrogel monomers (biomedical carriers, sensor substrates).
5. Organic synthesis intermediates: used for the synthesis of special polymers, medicines, pesticides, and dye intermediates.
Key Features
– Fast cationic UV curing, suitable for high-speed production lines
– Low viscosity, excellent thinning & leveling performance
– Low cure shrinkage, less curling and wrinkling
– Flexible ether backbone, improves toughness and adhesion of cured film
– Low odor compared with acrylic diluents
– Light & heat sensitive, stabilized with inhibitor
Packaging & Storage
Packing: Usually packed in 200kg/drum, and also can be do customized package.
Storage: Store in a sealed, dark place in a cool, ventilated area. The recommended storage temperature is below 30℃; keep away from heat sources, open flames, and oxidants. This product is prone to self-polymerization, and direct exposure to sunlight and high temperatures must be avoided.
Shelf Life: With proper storage and sufficient anti-oxidation agents.
