中固化学® PSS-DEN

(Photo-sensitizer Anthracure in cationic polymerization)

Chemical Name: 1,4-Diethoxynaphthalene

CAS No: 27294-37-7

Molecular Formula: C14H16O2

Molecular Structure:

产品概述 :

中固化学® PSS-DBA is a high-performance photo-sensitizer designed to enhance the efficiency of UV curing processes. It enables effective sensitization of both radical photo-initiators and cationic photo-acid generators (PAGs) under 365–405 nm UV-LED light sources, even with low inherent absorbance in this range. It is particularly suited for applications requiring low yellowness and high transparency.

规格说明 :

Appearance

White to Light yellow powder

Purity

≥99%


核心特性 :

  • Broad Compatibility: Works with radical and cationic UV systems.

  • Reduced Yellowness: Minimizes yellowing in cured films.

  • Oxygen Inhibition Resistance: Improves curing efficiency in both air and nitrogen atmospheres.

  • UV-LED Compatibility: Optimized for 365–405 nm UV-LED sources.

  • Enhanced Conversion: Increases monomer polymerization degree under various conditions.

  • Conjunctive use of PSS-DBA to give a boost to cure and to reduce yellowing

应用领域 :

  • UV-curable coatings, adhesives, and inks

  • High-clarity optical films and electronic 原料组分s

  • Cationic epoxy systems

  • Low-yellowing formulations for transparent substrates

Recommended Dosage :

  • Radical Systems 0.1 – 1.0

  • Cationic Systems 0.8 – 3.0

  • Hybrid Systems 1.0 – 2.0


贮存 :

Store in a dry, clean, ventilated warehouse.
Avoid exposure to light and heat.
