Description

1,3-Propanediol, 2-Ethyl-2-Hydroxymethyl-, Trimethacrylate is a specialized multifunctional methacrylate monomer, also known as trimethylolpropane trimethacrylate (TMPTMA). This compound is valued for its ability to form highly cross-linked, durable polymer networks with excellent chemical and thermal resistance. It is essential for manufacturers in the coatings, adhesives, and advanced polymer composites industries seeking to enhance the hardness, scratch resistance, and curing speed of their final products.

Application

• UV-Curable Coatings & Inks: A key cross-linking agent for formulating high-performance, fast-curing surface coatings, printing inks, and overprint varnishes.
• Adhesives & Sealants: Used to improve the cohesive strength, durability, and environmental resistance of acrylic-based structural and pressure-sensitive adhesives.
• Dental & Biomedical Polymers: Serves as a cross-linker in the production of dental composites, restorative materials, and other biocompatible polymer systems.
• Fiber Optics & Optical Lenses: Imparts high refractive index and stability in polymers used for optical claddings, lenses, and electronic encapsulants.
• Automotive & Industrial Coatings: Enhances the scratch, mar, and chemical resistance of clear coats and pigmented finishes.
• Photoresists & Electronics: Employed in the formulation of photopolymerizable resins for microelectronics and printed circuit boards.

Quality Control

Our production of Trimethylolpropane Trimethacrylate (TMPTMA) adheres to stringent quality management protocols. Every batch is analyzed to ensure high purity and consistent performance, with specifications typically covering assay, acid value, color, and inhibitor content. Certificates of Analysis (COA) are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat, sparks, open flames, and incompatible materials such as strong acids and oxidizing agents. For long-term storage, maintain under an inert atmosphere to prevent premature polymerization.
