IGM Omnirad EDB Photoinitiator液体

IGM Omnirad EDB is a high-efficiency tertiary amine synergist for photoinitiators in the Omnirad series, designed for UV free radical curing systems. Its core component is Ethyl 4-(dimethylamino)benzoate. When used with Type II photoinitiators, it can synergize efficiently, promote free radical generation, improve initiation efficiency, and quickly drive the polymerization of acrylates and other unsaturated oligomers. With strong compatibility and easy addition, it is a core auxiliary additive to improve performance and optimize construction efficiency in UV curing systems, also usable for synthesizing high-efficiency photosensitive materials and UV radiation protection scenarios.

Features Of IGM Omnirad EDB Photoinitiator

  1. Significant synergistic effect - Combined with Type II photoinitiators, it greatly increases the amount of free radicals, accelerates curing speed and improves curing degree

  2. Efficient auxiliary initiation - Makes up for the insufficient activity of single photoinitiators, reduces the impact of oxygen inhibition, and optimizes surface curing effect

  3. Multi-system compatibility - Suitable for solvent-based and water-based UV systems, compatible with various acrylate oligomers, strong versatility

  4. Easy liquid control - Colorless to pale yellow transparent liquid, easy to dissolve and add, accurate measurement and convenient processing

  5. Low odor and low volatility - Mild odor, low volatility, stable performance during storage and construction, excellent batch consistency

Typical Applications Of IGM Omnirad EDB Photoinitiator

  1. UV ink field - Offset, screen, flexo inks, combined with Type II initiators to improve curing efficiency and ensure printing precision

  2. UV coating field - Wood, plastic, metal UV coatings, optimize curing effect and enhance film adhesion and weather resistance

  3. Photosensitive material field - Synthesize high-efficiency photosensitive materials, suitable for photosensitive systems in photoelectric conversion devices

  4. Varnish field - Overprint varnishes, wood varnishes, improve curing speed and ensure coating gloss and transparency

  5. Universal UV system - Various UV free radical curing systems, assist in improving initiation performance and reducing formula cost
