Exposed asphalt surfaces on building roofs, roads, and bridges are highly prone to issues such as material aging, crack propagation, and localized spalling due to prolonged exposure to ultraviolet rays, rain erosion, and daily temperature fluctuations. These problems not only damage the appearance but also accelerate leakage and exacerbate structural corrosion, posing significant risks to the safety and service life of the structures.

In response to the issues faced by asphalt surfaces, Weldon has launched the independently developed W9 roll-applied silicone rubber waterproof protective coating. This product is tailor-made for asphalt surfaces and provides comprehensive protection for buildings through a 'one-coat, multiple-effects' systematic solution.

Weldon focuses on building safety and sustainable development, using innovative technology to create long-lasting, safe structures, actively implementing the 'dual carbon' strategy, and supporting urban renewal.
