Features :

Direct Performance Replacement: Serves as a high-performance, cost-effective alternative to ANTHRACURE UVS-1101, offering identical chemical structure and equivalent or superior sensitizing performance.
Proven Efficiency Enhancement: In free radical systems, enables a significant reduction of primary photo-initiator dosage (e.g., benzophenone types) while maintaining or improving monomer conversion rate and cure depth, leading to optimized formulation cost.
Dual-Mode Sensitization: Effectively sensitizes both cationic photo-initiators (iodonium/sulfonium salts) and Type II free radical photo-initiators, broadening formulation versatility.
Excellent UV-LED Compatibility: Its strong absorption spectrum perfectly matches mainstream UV-LED outputs (365nm, 385nm, 405nm), enabling efficient, energy-saving curing with enhanced speed and depth.
Regulatory Advantage: Relevant anthracene-based photosensitizers are listed in the Swiss Ordinance Annex 10, supporting compliance for demanding applications such as food packaging inks and coatings.

Application :

SINOCURE® PSS-DEA is ideal for high-performance, LED-compatible UV-curable systems requiring efficiency, deep cure, and regulatory consideration:

Coatings & Inks: Especially for food packaging, plastic, wood, and metal substrates.
Adhesives & Sealants: Optical adhesives, electronic potting, and assembly adhesives.
3D Printing: Photosensitive resins for SLA/DLP technologies.
Electronic Materials: Conformal coatings, encapsulants.
Composite Materials: Fiber-reinforced polymer (FRP) curing.

Recommended Dosage :

In Free Radical Systems (with Type II PIs): 0.5% - 1.0% of total formulation weight.
In Cationic Systems (with onium salts): 0.1% - 0.5% of total formulation weight.
The optimal dosage should be determined through practical testing based on specific formulation, photo-initiator, and light source.
Incorporation: Add during the mixing stage of the oil phase. Ensure uniform dispersion.

Packaging & Storage :

1kg, 10kg,20kg Bag/Carton
