性能特点 :

  • Direct Performance Replacement: Serves as a high-performance, cost-effective alternative to ANTHRACURE UVS-1101, offering better 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 单体 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.

应用体系 :

SINOCURE® PSS-DEA Et is ideal for high-performance, LED-compatible UV光固化 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.

使用建议与添加量 :

  • 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.

储存 :

  • 1 公斤, 10 公斤,20 公斤 Bag/Carton

  • Store in a dry, clean, ventilated warehouse.
    Avoid exposure to light and heat.
    Be careful to prevent leakage, rain and sun during transportation.
