Applications
- Dental & Medical Materials A low-viscosity dimethacrylate monomer used in dental restorative composites, adhesives. Reduces formulation viscosity while improving flexibility and water resistance, delivering reliable performance in precision dental applications.
- 3D Printing & UV-Curable Resins A high-reactivity monomer for SLA and DLP 3D printing resins, UV inks, coatings and adhesives. Fast curing, low shrinkage and good toughness enable precise, dimensionally stable printed and coated parts.
- UV Coatings, Inks & Adhesives Improves cure speed, flexibility and adhesion of UV-curable coatings, inks and adhesive systems. Consistent purity and controlled viscosity ensure stable processing in high-speed production lines.
- Contact Lens & Optical Materials A hydrophilic monomer contributing to oxygen permeability and surface wettability in contact lens and optical material formulations. High purity grades support consistent optical and mechanical properties.
Quality Assurance
Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.
Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
Packaging
Export-grade packaging, custom labels
Solids (woven bags/cardboard drums/ton bags)
