Description

General description

Tri(propylene glycol) diacrylate (TPGDA) is a multifunctional acrylate monomer characterized by its high reactivity and ability to polymerize rapidly under UV or thermal initiation. Its structure includes multiple acrylate groups, which contribute to its crosslinking capability, enhancing the mechanical properties of the resulting polymers. The low viscosity of TPGDA facilitates easy handling and incorporation into formulations.

Application

Tri(propylene glycol) diacrylate, mixture of isomers can be used:

• As a cross linker to synthesize resins for flexible micromaterials via projection microstereolithography (PμSL) screening formulations to fabricate microfluidic devices for cellular biosensors.
• As a dopant to prepare pure organic molecules with persistent luminescence at room temperature via intramolecular electronic coupling for forensic fingerprint detection.
• As a precursor to prepare high mechanical resilience double network hydrogel adhesives for wound healing patches.
