Cracking, leakage, and aging of concrete bases caused by long-term exposure have become increasingly prominent, commonly seen in old residential areas, elevated bridges, and other structures. This not only directly threatens structural safety but also shortens the service life of buildings. Driven by the 'dual carbon' goals and urban renewal policies, improving building durability has become a key focus in the industry today.

Facing challenges such as aging, leakage, and cracking of concrete substrates, Weldon has launched the W9 Concrete Protection Silicone Waterproof Coating, specifically developed for concrete surfaces, based on advanced silicone rubber technology. This product integrates three core functions: waterproofing, corrosion resistance, and thermal insulation.

1. Anti-aging, ultra-long weather resistance, artificial climate aging ≥3000h, no cracking or chalking, strength retention over 95%. 2. Features high strength and high wear resistance, can be walked on immediately after application. 3. Under conditions of -20°C to 50°C, after 100 freeze-thaw cycles, the coating shows no abnormalities. 4. Waterproof at 0.3MPa for 120 minutes, effectively preventing leaks and providing complete protection. 5. The coating has excellent flexibility and elasticity, effectively resisting cracking caused by substrate movement. 6. Bond strength ≥1.5MPa, no blistering, peeling, or detachment. 7. Effectively reflects visible and infrared solar radiation, providing heat insulation and cooling. 8. No need for removal or work stoppage; easy application saves costs. 9. Acid and alkali test for 168h retains over 95% strength. 10. Salt spray resistance for 1500h, coating remains normal, protecting the concrete substrate from chemical damage. 11. Suitable for environments from -50°C to +150°C, applicable to severe cold, high altitude, and large day-night temperature differences.

W9 Concrete Protection Silicone Rubber Waterproof Protective Coating is based on technological innovation and, with its long-lasting, energy-saving, and reliable excellent quality, actively responds to the national call for green development and urban renewal. Weldon is always focused on safeguarding building safety and enhancing building durability, using solid and reliable innovative technology to help buildings rejuvenate and lay a solid foundation for sustainable urban development.
