Application
1. Serves Tri(propylene glycol) diacrylate as a reactive diluent in UV/EB-curable coatings, reducing formulation viscosity while boosting cured film flexibility, adhesion and chemical resistance for wood, plastic and metal coating systems reliably.
2. Acts TPGDA CAS 42978-66-5 as a crosslinking monomer in printing inks, enhancing curing speed and durability of flexographic, screen and offset inks and overprint varnishes effectively.
3. Functions as a key component in electronic encapsulation resins, supporting UV-curable potting materials to improve insulation and moisture resistance of electronic components stably.
Storage and Precautions
Store Tri(propylene glycol) diacrylate (TPGDA, CAS 42978-66-5, colorless-to-pale yellow liquid, MEHQ-stabilized, flash point 174℃, viscosity 10-20 mPa·s, purity ≥98%) at 5–25℃ in sealed HDPE/amber glass drums in a cool, dry, dark, well-ventilated area. Isolate from strong oxidants, UV light and free radicals to avoid premature polymerization. Wear nitrile gloves, safety goggles and splash shield; avoid skin/eye contact, vapor inhalation and ingestion to prevent irritation. Reseal tightly post-use; dispose of waste per local UV-curable monomer & acrylate environmental regulations.
What are the benfits of taking Tri(propylene glycol) diacrylate / TPGDA?
Tri(propylene glycol) diacrylate is an industrial UV-curable monomer, not for direct pure-form human contact or ingestion; undiluted contact may cause skin/eye irritation, and accidental intake will lead to gastrointestinal discomfort. In regulated applications, TPGDA CAS 42978-66-5 features low volatility & low shrinkage, excellent compatibility with UV resins, and balanced reactivity & flexibility to optimize cured product performance and production efficiency.
