Denso Launches Densoband for Sealing Asphalt Joints

Denso now offers Densoband, a hot asphalt bituminous sealing strip designed for sealing joints and surfaces between asphalt, concrete and steel. Densoband is composed of a polymer-modified bitumen strip to enhance flexibility and durability, enabling it to accommodate movement caused by heavy traffic loads and thermal changes. Its uniform, watertight and flexible seal prevents water ingress, reducing erosion and deterioration of joints over time.

The product’s adhesion to primed surfaces offers a strong bond to asphalt, concrete or steel. Its high durability allows it to withstand heavy traffic loads and environmental stressors, according to the manufacturer. Additionally, Densoband’s flexibility enables it to accommodate thermal expansion and contraction without cracking or propagating damage, further extending the lifespan of the joint.

Densoband simplifies the installation process with its integrated adhesive system, which eliminates the need for flame application. The product can be applied by hand or machine, with an application temperature range of +41°F to +113°F. Furthermore, its cold bend behavior ensures no cracking occurs at 0°C, according to the manufacturer.
