Storage Requirements

Store in tightly sealed nitrogen-purged containers away from light at 2–25℃, shield from UV light and direct sunlight.

Do not co-store with peroxides, strong oxidants and strong alkalis to prevent premature gelation of methacrylate double bonds.

Keep packaging fully airtight to isolate air and moisture; standard shelf life is 6 months.

Stay away from high-temperature heat sources and open flames, maintain well-ventilated and dry warehouse environment.


Mw 8000-12000

Custom  specifications are available upon customer request.

Core modifying monomer for UV curable crosslink coatings & inks: Copolymerize with acrylic resins to enhance coating smoothness, scratch resistance, hydrophobic anti-graffiti property and outdoor weather resistance, reduce curing internal stress without silicone migration.

Crosslinker for SLA 3D printing photosensitive resins: Improve printed parts’ toughness, dimensional stability and solvent resistance, suitable for optical and precision component manufacturing.

Raw material for optical films, liquid optical adhesives and optical fiber protective coatings: High light transmittance and low internal stress for display and optoelectronic precision films.

Synthetic monomer for silicone-modified acrylic resins & emulsions: Prepare water-resistant, abrasion-resistant, low-surface-energy coatings, leather & textile finishing agents.

Migration-free UV reactive release agent: Long-term release performance for optical films and precision molds without silicone contamination.

Biomedical polymer raw material: Crosslink monomer for contact lenses and biocompatible hydrogels to boost oxygen permeability and surface lubricity.

UV curable conformal coating for PCBs & electronic protection: Wide temperature resistance, hydrophobic insulation and anti-cracking performance.
