Product Information Item Information Product Name Diethylene Glycol Divinyl Ether Product Code YLD-S0101 Chemical Name 1-(2-[2-(Vinyloxy)ethoxy]ethoxy)ethylene, 1,1-[oxybis(2,1-ethanediyloxy)bis]ethene CAS No. 764-99-8 Molecular Formula C8H14O3 Molecular Weight 158.20 g/mol Category Low-viscosity, highly reactive di-functional vinyl ether monomer     2. Product Description YLD-S0101 is a low-viscosity, highly reactive di-functional vinyl ether monomer. The double bonds in its molecular structure give it rapid curing properties, while the flexible ether chains significantly improve the flexibility and hydrophilicity of the material. It can be used as an active diluent, cross-linking monomer or modifier and is widely applied in light-curing, UV-curing systems, coatings and adhesives to regulate the viscosity of the system and enhance the comprehensive performance of the cured product.   3. Structure Features and Key Advantages 1. Di-functional vinyl ether structure YLD-S0101 contains vinyl ether reactive groups and can be used in light-curing and UV-curing systems to support rapid curing. 2. Low viscosity and good diluting effect The company TDS lists Low viscosity and good diluting effect as key features, which support viscosity adjustment and processing performance in formulation systems. 3. Flexible ether chains The flexible ether chains help improve flexibility and hydrophilicity of the cured material, making it suitable for formulations requiring reactivity, flexibility and processability.   4.
