Chemical name：Ethoxylated Trimethylolpropane Triacrylate

CAS NO.: 28961-43-5

Formula: C45H80O21

Molecular weight: 957 g/mol

Introduction:

Easmer 15EO-TMPTA is a trifunctional acrylate monomer derived from trimethylolpropane

(TMP) by ethoxylation with approximately 15 ethylene oxide units followed by acrylation.

The ethoxylation introduces flexibility and reduces the crosslink density compared to

non-ethoxylated TMPTA, resulting in more flexible and less brittle cured films. It is

commonly used in UV-curable coatings, inks, and adhesives where flexibility, impact

resistance, and good adhesion are required.

Performance:

Good flexibility,Hydrophilicity
