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.

The use of ultraviolet radiation-curable coatings (UV-coatings) has increased rapidly in the parquet and furniture industry. Work with UV-coatings involves risk from skin exposure to chemically reactive, concentrated acrylates that are known skin contact irritants and sensitizers. Yet, the methods

Current methods for measuring dermal exposure to skin irritants and allergens, such as acrylates, have significant drawbacks for exposure assessment. A noninvasive sampling method has been developed and tested for measuring dermal exposure to a multifunctional acrylate employing a tape

The toxicity of the esters of acrylic acid are poorly understood even though significant human exposure occurs. To conduct rapid comparative short-term bioassays, we used the Tg.AC (v-Ha-ras) transgenic mouse model to determine the toxicity and potential carcinogenicity of tripropylene

The potential for occupational exposure to the esters of acrylic acid (acrylates) is considerable, and, thus, requires a greater understanding of the their toxicity. Confluent (70-90%) cultures of normal human epidermal keratinocytes (NHEK), dermal fibroblasts (NHDF). or bronchial epithelium (NHBE)

Acrylates may be polymerized to stable surface coatings (paints, lacquers, inks, etc.) by alkylation via the Michaelis-type addition reaction. Thus, acrylates have an inherent potential as electrophiles to be genotoxic, limited in their biological activity by their physicochemical properties. To
