- 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 TMPTA
- Performance Highlights
TMPTA is characterized by:; Low viscosity; Low color; UV/EB curable formulated products containing TMPTA are characterized by:; High cross-link density; Rapid cure response; High gloss; Excellent hardness; Good chemical resistance; 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
TMPTA is a cost effective diluent compatible with the wide range of acrylated resins used in radiation curing applications. Its ability to enhance reactivity, hardness, gloss, and chemical and wear resistance properties makes TMPTA popular for overprint varnishes, inks, coatings, traffic striping paints and rubber crosslinking.
