Description

2,2-Bis(Hydroxymethyl)-1,3-Propanediyl Diacrylate is a high-purity, difunctional acrylate monomer characterized by its two reactive hydroxyl and acrylate groups. This unique bifunctional structure makes it a critical building block for creating highly cross-linked polymer networks with enhanced mechanical strength, chemical resistance, and thermal stability. It is essential for formulators and manufacturers in the coatings, adhesives, and advanced materials sectors seeking to develop high-performance, durable end-products.

Application

• UV-Curable Coatings & Inks: A key monomer for formulating high-gloss, scratch-resistant, and fast-curing coatings for wood, plastic, and metal substrates.
• Adhesives & Sealants: Used to produce high-strength, durable structural and pressure-sensitive adhesives with excellent adhesion to diverse surfaces.
• Dental & Biomedical Materials: Serves as a cross-linking agent in dental composites, bone cements, and other biocompatible polymer systems.
• Photoresists & Electronic Materials: Employed in the production of photopolymerizable resins for printed circuit boards (PCBs) and microelectronics.
• Fiber Optic Coatings: Provides protective, cross-linked coatings that enhance the durability and signal integrity of optical fibers.
• 3D Printing Resins (SLA/DLP): A vital component in formulating high-resolution, tough, and dimensionally stable resins for additive manufacturing.

Quality Control

Our 2,2-Bis(Hydroxymethyl)-1,3-Propanediyl Diacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profiles, and physical properties is provided with each shipment to guarantee consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is light-sensitive and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability and to minimize polymerization risk. Keep away from heat, sparks, and open flame.
