Description

(1-Methylethylidene)Bis[(2-Methyl-4,1-Phenylene)Oxy(1-Methyl-2,1-Ethanediyl)] Diacrylate is a specialized, high-purity difunctional acrylate monomer. This compound matters for its role as a key reactive diluent and crosslinking agent in advanced polymer formulations, enabling the creation of materials with enhanced durability and specific performance characteristics. Industrial R&D and production teams in the coatings, adhesives, and advanced composites sectors need this monomer to develop high-performance, radiation-curable systems.

Application

• UV/EB Curable Coatings: Acts as a reactive diluent and crosslinker in formulations for wood, plastic, and metal coatings, providing excellent hardness and chemical resistance.
• Adhesives & Sealants: Used in the synthesis of pressure-sensitive adhesives (PSAs) and structural adhesives requiring fast cure times and strong bonding performance.
• Photoresists & Electronics: Serves as a critical component in photopolymerizable resins for printed circuit boards (PCBs) and microelectronic encapsulants.
• Dental & Medical Polymers: Employed in the production of biocompatible, light-curable composites for dental restoratives and medical device coatings.
• Inks & 3D Printing Resins: A functional monomer in energy-curable printing inks and stereolithography (SLA) resins, contributing to precise curing and fine detail.
• Fiber Optic Coatings: Used in coatings that protect optical fibers, offering low shrinkage and excellent environmental stability upon curing.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Every lot is analyzed for critical parameters including purity, identity, and impurity profile. Certificates of Analysis (COA) documenting these results are available upon request. We adhere to a quality management system to support our commitment to supplying reliable, high-performance chemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, consider maintaining under an inert gas such as nitrogen.
