Ethyl-4-dimethylaminobenzoate

• Appearance: White to off-white crystalline powder

• Assay (HPLC): ≥ 99.0% (High Purity)

• Melting Point: 62.0°C – 67.0°C

• Volatiles: ≤ 0.5%

• Absorption Peak: 300nm – 308nm (Methanol)

• Solubility: Insoluble in water; soluble in most organic solvents and UV monomers.

A powerful synergist for UV curing efficiency:

• Combats Oxygen Inhibition: Acts as an active hydrogen donor to neutralize oxygen inhibition, ensuring fast surface curing even in thin films.

• Type II Synergist: Essential co-initiator for Type II photoinitiators (e.g., ITX, DETX, BP) to generate reactive free radicals.

• Performance: Enhances the curing speed and hardness of the final coating without yellowing.

• Applications: Widely used in UV offset inks, flexo inks, screen printing inks, and electronic coatings.

Packaging: 25kg Carton Box (inner PE bag) or 20kg Fiber Drum.

Storage: Keep in a dark, cool, and dry place. Avoid direct sunlight to prevent premature polymerization.
