Products Description
The dual-functional crosslinking structure effectively increases the crosslinking density of the system. After curing, the products have high hardness, good anti-abrasion and wear resistance, as well as water and sweat resistance.
The viscosity is moderate, which can act as an active diluent to adjust the formulation's construction viscosity. The curing shrinkage is controllable, and the toughness is excellent. It has excellent compatibility with acrylic systems and is suitable for various scenarios such as plastic varnishing, dental consumables, electronic protection, 3D printing, etc.

FAQ
Q: Could DEGDMA be used for anaerobic adhesive?
A: Yes, it serves as cross‑linking component to enhance bonding strength and sealing performance.
Q: What happens under high‑temperature storage?
A: Inhibitor will be consumed, resulting in spontaneous polymerization and gelling.
Q: What is the main role of DEGDMA in UV formulations?
A: Difunctional cross‑linking monomer, it acts as reactive diluent to reduce viscosity and improves cross‑link density, hardness and water resistance.
Q: Could it be compounded with unsaturated polyester?
A: Yes, widely used in artificial marble as co‑crosslinker to improve strength and gloss.
Q: How is the chemical resistance of cured DEGDMA?
A: Good resistance to water, dilute acid and alkali, but attacked by ketones and halogenated solvents.
