High reactivity under UV-A and visible light (365–405 nm), enabling efficient curing with LED sources.
Low yellowing tendency, supporting excellent long-term clarity and color stability in transparent coatings.
Excellent compatibility with acrylate-based resins, including multifunctional monomers and oligomers.
Good solubility in common reactive diluents and low volatility, contributing to reduced odor and improved handling safety.
Non-migrating structure ensures compliance with food-contact regulations when formulated appropriately.
UV-curable clear coats for wood and plastic substrates.
LED-curable inks for digital inkjet printing (e.g., packaging, decorative graphics).
Optical adhesives and encapsulants requiring high transparency and low haze.
3D printing resins for stereolithography (SLA) and digital light processing (DLP) systems.
Electronics encapsulation and conformal coatings demanding rapid through-cure and minimal post-cure shrinkage.
