Ethylene Glycol Dimethacrylate

1. Crosslinking agent in UV-curable and thermoset systems: Ethylene glycol dimethacrylate is widely used as a difunctional crosslinker to increase network density, hardness and solvent resistance in UV-curable coatings, inks and adhesives. Incorporation of EGDMA improves mechanical strength, chemical resistance and reduces tackiness after cure while enabling rapid photopolymerization in free-radical systems. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Ethylene glycol dimethacrylate (CAS 97-90-5).
2. Dental and medical resins: EGDMA is a common comonomer in dental restorative formulations and prosthetic resins where dimensional stability and crosslinking are required. It contributes to shrinkage control, increased flexural strength and improved wear resistance when combined with appropriate fillers and photoinitiators. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Ethylene glycol dimethacrylate (CAS 97-90-5).
3. Molded plastics and specialty polymers: as a reactive diluent, EGDMA reduces viscosity for processing while becoming covalently bound in the cured matrix. This dual role enables lower processing temperatures and improved filler wetting during production of molded parts and specialty composites. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Ethylene glycol dimethacrylate (CAS 97-90-5).
4. Adhesives and sealants: the use of EGDMA in pressure-sensitive adhesives and structural adhesives enhances cohesive strength and thermal stability after curing. It permits formulators to tailor cure speed and final modulus by adjusting EGDMA content relative to monofunctional acrylates. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Ethylene glycol dimethacrylate (CAS 97-90-5).
5. Surface coatings and inks: addition of EGDMA increases abrasion resistance and chemical durability in coatings for flooring, electronics and printed media. It is particularly valuable in systems where fast UV cure and high crosslink density are necessary for end-use performance. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Ethylene glycol dimethacrylate (CAS 97-90-5).
6. Handling and benefits summary: EGDMA is supplied with inhibitor to prevent premature polymerization; KieRay Chem provides COA and storage recommendations. Benefits include effective multifunctional crosslinking, improved mechanical and chemical properties, reduced viscosity as a reactive diluent, and compatibility with standard radical photoinitiators and thermal cure systems. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Ethylene glycol dimethacrylate (CAS 97-90-5).
