Looking for the right polyurethane sealant for your next project?

Polvurethane sealants are used in many different applications, but the best product depends on the job. A self-leveling PU sealant for concrete expansion joints is not the same as a windshield bonding adhesive, a waterproof coating, or a corner assembly adhesive for aluminum windows.

Our latest guide explains the key differences between polyurethane sealant types and shows how to choose and apply the right product for:
• Concrete expansion joints
• Roads, bridges, airport pavements, and industrial floors
• Automotive windshields and side windows
• Curtain walls, façades, windows, and doors
• Roofs, basements, and waterproofing systems
• OEM, private-label, and customized projects

The guide also covers surface preparation, joint design, backing materials, curing conditions, compatibility testing, and technical data sheet selection.
