Magna-Tech Manufacturing, now part of Henkel Corporation, North America

The acquisition of Magna-Tech Manufacturing in December 2015 expands Henkel’s role from a resin provider for vacuum impregnation in North America to one that also offers process center services and equipment solutions — adding to Henkel’s existing network of European and Asian process centers.

Magna-Tech functions as a subsidiary of Henkel Corporation, operating as part of its Adhesive Technologies business.
