IGM Omnirad EHA is a high-efficiency tertiary amine UV photoinitiator synergist in the Omnirad series, designed for UV free radical curing systems. Its core component is 2-Ethylhexyl 4-(dimethylamino)benzoate, a key auxiliary additive in UV curing reactions. When used with Type II photoinitiators, it can synergize efficiently, promote free radical generation, reduce the impact of oxygen inhibition, and quickly drive the polymerization of acrylates and other unsaturated oligomer
High-efficiency Type I initiation - Acylphosphine oxide structure, high free radical initiation efficiency and excellent deep curing effect
Easy liquid processing - Clear yellow liquid, easy to add, good fluidity, accurate measurement, suitable for continuous production
Low-yellowing and weather resistance - No obvious yellowing after curing, excellent weather resistance, better than traditional TPO, suitable for high appearance scenarios
Broad-spectrum compatibility - Compatible with solvent-based and water-based UV systems, soluble in various coating solvents and UV monomers
Excellent compounding performance - Can be compounded with various photoinitiators to optimize curing performance, suitable for transparent, pigmented and other formulations
UV ink field - Offset, screen, flexo inks, suitable for wood, metal, plastic and other substrates, high printing precision
Coating field - Wood, metal, plastic UV coatings, uniform curing, improving coating wear resistance and decorativeness
Adhesive field - Universal UV curing adhesives, suitable for paper, optical fiber and other substrates, high bonding strength
3D printing field - 3D printing photocurable resins, high initiation efficiency, improving printing molding speed and precision
Optical fiber coating field - UV protective coatings for optical fiber surfaces, fast curing, good fit and excellent protective performance
