Polyurethane Construction Adhesives

Strong, Flexible & Proven

Polyurethane Adhesives & Sealants

Heavy-duty 1-C polyurethanes for construction, marine, and transportation.

Polyurethane (PU) adhesives and sealants are the heavy-duty workhorses of structural bonding—delivering outstanding strength, elasticity, and durability across a massive range of substrates.

These one-component (1-C), moisture-curing systems are universally trusted by professionals to replace mechanical fasteners in applications where extreme bond strength, shock absorption, and movement capability are essential.

Structural Strength

Exceptional tensile and lap shear strength. Can easily replace mechanical fasteners, rivets, and welding in structural assemblies.

Shock & Vibration

Permanent elasticity absorbs extreme dynamic stresses, impacts, and cyclic loading typical in transportation and marine environments.

Paintable & Sandable

Unlike traditional silicones, polyurethanes can be sanded flush and painted over once fully cured for seamless OEM finishing.

Core Applications for 1-C Polyurethane

Marine & Boat Building

The industry standard for above and below waterline sealing. Perfect for bedding deck hardware, hull-to-deck joints, and structural structural fiberglass bonding.

Transportation & Specialty Vehicles

Used heavily in RV, trailer, and truck body manufacturing. Absorbs constant road vibration while bonding metal panels, fiberglass roofs, and trim.

Commercial Construction

Highly trusted for heavy-duty expansion joints, floor joints, precast concrete crack repair, and sealing masonry structures against the elements.

Wood, Subfloor & General Assembly

High-tack formulations provide exceptional instant grab for roofing, decking, drywall installation, and demanding wood-to-concrete subfloor assemblies.
