Polyurethane sealants are mostly one-part materials that show excellent adhesion and elongation. Polyurethane’s are non-corrosive, paintable and very flexible. Polyurethane’s will adhere to most substrates, perform well under a wide temperature range and exhibit resistance to many chemicals and weathering.

Ellsworth Adhesives supplies PU sealants manufactured by Robnor Resinlab, 3M and Permabond.
