- Storage and Handling
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.. See the SDS for the recommended storage temperature range for TPGDA.
- Performance Highlights
TPGDA is characterized by:; Low viscosity; Good diluency of acrylate oligomers; Hydrophobicity; UV/EB curable formulated products containing TPGDA 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 photoinitiators.
- Compatible Substrates and Surfaces
- Wood
- Known For
TPGDA finds application in UV/EB cured ink and coating systems.; TPGDA is an especially useful reactive diluent when water resistance and low viscosity are required.; Dilution of viscous oligomers or polymers
