Description

General description

(2-Ethyl-2-(hydroxymethyl)-1,3-propanediol polymer with (chloromethyl)oxirane has a trifunctional aliphatic glycidyl ether epoxide monomer mainly used as a crosslinking agent which provides chemical and mechanical resistance.

Application

Additive in fast-setting adhesives, low temperature curing coatings and hard, abrasion resistant castings and decoupage systems.

(2-Ethyl-2-(hydroxymethyl)-1,3-propanediol polymer with (chloromethyl)oxirane is used in the synthesis of azidated trimethylolpropane triglycidyl ether for the preparation of polyether polyol based hyperbranched polyurethanes. It can be coated on polycarbonated chips for improving chemical resistance from different organic solvents. Cross-linking of (2-Ethyl-2-(hydroxymethyl)-1,3-propanediol polymer with (chloromethyl)oxirane can be done with poly(4-venylphenol) (PVP) for the preparation of organic field effect transistors (OFETs).

Features and Benefits

Reduces viscosity but retains high epoxide level, imparts hardness and toughness to epoxide polymers. Improves solubility/compatibility characteristics of highly aromatic epoxy systems.
