Description

EP0408.01.30 is a hybrid molecule with an inorganic silsesquioxane at the core and organic epoxycyclohexyl 

groups attached at the corners of the cage. This formulation contains 30% PGMEA for coating applications. 

EP0408.01.30 can be cured with aromatic, aliphatic amines and photoinitiators. EP0408.01.30 provides increased 

use temperature, excellent water and solvent resistance and enhanced thermomechanical performance.

Applications: 

Additive for cationic and thermal cure hard coatings with optical clarity. Can also be utilized 

as a dispersant and rheological diluent for high shear applications.
