Description
EO9-TMPTA — Ethoxylated (9) trimethylolpropane triacrylate
CHLUMICRYL® EO9-TMPTA is the nominal nine-EO grade of ethoxylated trimethylolpropane triacrylate. It combines a polyether segment with three acrylate groups and is a candidate for flexible UV/EB-curable formulations.
Product Identification

| Grade designation | Nominal 9EO grade |
The CAS number identifies the chemical family. The grade designation and current product specification are needed to identify the material for an order.
Applications and Formulation Screening
- Flexible UV coatings and overprint varnishes.
- Printing-ink blends in which flexibility and substrate wetting need to be evaluated.
- Adhesive and pressure-sensitive adhesive development using multifunctional acrylates.
Grade Selection and Formulation Guidance
EO9-TMPTA has a different ethoxylation level from EO3-TMPTA and EO6-TMPTA. Compare water affinity, viscosity and film properties experimentally instead of replacing one EO grade solely on the basis of its CAS number. Cure response also depends on the oligomer and initiator package.
Specification and Quality Documents
Please request the current TDS, SDS and available lot COA. Quotation and sample approval should establish the applicable assay or active-content method, viscosity and test temperature, color, acid value, moisture, and inhibitor type and level. Numerical release limits are confirmed for the offered grade.
Request a Sample or Quotation
Specify the 9EO grade, substrate and expected flexibility in the inquiry. For a grade change, provide the existing monomer designation and the performance targets used to approve a replacement.
Include the quantity, destination and packaging preference. Commercial packaging, minimum order quantity and lead time are confirmed with the quotation. Follow the current SDS and container instructions for handling and storage.
