Description

1,2-Propanediol Dimethacrylate is a high-purity, difunctional methacrylate monomer. This compound is valued for its excellent crosslinking efficiency and reactivity, which are critical for creating durable polymer networks. It is primarily sought after by manufacturers in the coatings, adhesives, and advanced polymer industries for applications requiring enhanced hardness, chemical resistance, and fast curing properties.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and crosslinker in formulations for wood, plastic, and metal coatings, providing rapid cure speeds and high surface hardness.
• Dental & Medical Polymers: Used in the production of dental composites, restorative materials, and bone cements due to its biocompatibility and strong polymer matrix formation.
• Adhesives & Sealants: Imparts superior adhesion, toughness, and environmental resistance in acrylic-based structural and industrial adhesive systems.
• Fiber Optics & Optical Lenses: Employed in casting resins for optical components, offering high clarity, precise refractive index control, and low shrinkage.
• Printing Plates & Photoresists: Serves as a photopolymerizable component in liquid and sheet photoresists for printing and microelectronics.
• Composite Materials: Acts as a matrix resin or crosslinking agent in fiber-reinforced plastics (FRP) and gel coats, enhancing mechanical strength and durability.

Quality Control

Our 1,2-Propanediol Dimethacrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity verification, to ensure it meets precise specifications for reactive monomer applications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This product 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 under an inert gas blanket such as nitrogen or argon to inhibit premature polymerization.
