PRODUCT INTRODUCTION

description

Ethylene glycol dimethacrylate is the enoate ester that is the 1,2-bis(methacryloyl) derivative of ethylene glycol. It has a role as a cross-linking reagent, a polymerisation monomer and an allergen. It is functionally related to an ethylene glycol and a methacrylic acid.
