Understanding the chemical properties of essential industrial monomers is key for effective formulation and product development. Di-TMPTA (CAS: 94108-97-1), a tetrafunctional acrylate monomer, possesses a unique set of characteristics that make it indispensable in various high-performance applications, particularly in UV-curable systems. As a leading chemical manufacturer and supplier, we aim to provide clarity on this versatile compound.

Chemical Profile of Di-TMPTA:

Di-TMPTA, chemically known as Di-trimethylolpropane tetraacrylate, has the molecular formula C24H34O9 and a molecular weight of 466.52. It is typically supplied as a clean and clear liquid, with a high assay of 99% minimum. Its structure features four acrylate functional groups, which are highly reactive under UV or electron beam (EB) radiation. This tetrafunctionality is the foundation of its ability to form densely crosslinked polymer networks.

Key Chemical Properties and Their Significance:

  • Tetrafunctionality: The presence of four acrylate groups allows for a high degree of crosslinking during polymerization. This leads to cured materials with exceptional hardness, chemical resistance, and thermal stability.
  • Low Viscosity: Di-TMPTA exhibits relatively low viscosity compared to other multifunctional monomers. This property makes it an excellent reactive diluent, effectively reducing the viscosity of formulations without compromising the final cured properties. This is crucial for ease of processing and application.
  • High Reactivity: The acrylate groups are highly responsive to free radical polymerization initiated by UV light or electron beams. This ensures rapid curing, which is vital for high-speed industrial processes in coatings, inks, and adhesives.
  • Good Compatibility: Di-TMPTA generally shows good compatibility with various oligomers, resins, and other monomers used in UV-curable formulations, allowing for flexibility in formulation design.
  • Stability: It is typically supplied with a stabilizer (like MEHQ) to prevent premature polymerization during storage and transport, ensuring product integrity.

Primary Applications Driven by its Properties:

The unique combination of these properties makes Di-TMPTA a preferred choice in:

  • UV-Curable Coatings: Enhancing scratch resistance, hardness, and adhesion for automotive, industrial, and wood coatings.
  • UV-Curable Inks: Providing fast curing, excellent adhesion, and durability for printing applications.
  • Adhesives and Sealants: Formulating strong, fast-setting UV-curable adhesives for electronics, optics, and general assembly.
  • 3D Printing Resins: Acting as a critical component for high-resolution, mechanically robust photopolymer resins used in SLA and DLP printing.
