Laromer HDDA Hexandiol diacrylate BASF Crosslinking / Coupling / Curing Agents Coatings >> UV / Radiation Curing Miscible in most organic solvents Laromer HDDA (Hexandiol diacrylate) Laromer HDDA contains two polymerizable acrylic groups per molecule, which enable it to form copolymers of, for example, acrylic or methacrylic acids and their salts, amides, esters, vinyl acetate and styrene. Laromer HDDA is also an important feedstock for chemical syntheses because it readily enters into addition reactions. The polymerizable groups allow the product to be used as a crosslinking component, eg in radiation-curing coatings, where it also acts as a thinner. During curing, the Laromer HDDA becomes part of the polymer structure. Hexandiol diacrylate. Used as a crosslinking component and a thinner in radiation-curing coatings.
