TPGDA-A

TPGDA-A is a difunctional reactive diluent with a branched alkyl polyether backbone. Polymerization occurs when TRIPROPYLENE GLYCOL DIACRYLATE is exposed to sources of free radicals. It is widely used as a primary diluent in the formulation of ultraviolet light (UV) and electron beam (EB) curable coatings and inks. TRIPROPYLENE GLYCOL DIACRYLATE is a grade of tripropylene glycol diacrylate with lower inhibitor content than the standard grade (TPGDA).

Features & Benefits

CASE Ingredients Features
Product Performance

TPGDA-A is characterized by:

  • Low viscosity
  • Good diluency of acrylate oligomers
  • Hydrophobicity

UV/EB curable formulated products containing TPGDA-A are characterized by:

  • Good flexibility
  • Improved water resistance
  • Good cure speed without brittleness

The actual properties of UV/EB cured products also depend on the selection of other formulation components such as oligomers, additives and photo initiators.

Storage & Handling

Storage Conditions

Care should be taken not to expose the product to high temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis or acids. This might cause uncontrollable polymerization of the product with the generation of heat. Storage and handling should be in stainless steel, amber glass, amber polyethylene or baked phenolic lined containers. Procedures that remove or displace oxygen from the material should be avoided. Do not store this material under an oxygen free atmosphere. Dry air is recommended to displace material removed from the container. Wash thoroughly after handling. Keep container tightly closed. Use with adequate ventilation.
