Ultra-high Performance Weatherproof Silicone Sealant

Ultra-high performance weather-resistant silicone sealant: JS-2900 is a one-component, neutral-curing silicone sealant specifically designed for weather resistance and waterproof sealing in the curtain walls of ultra-high-rise buildings. It can be easily extruded and used at temperatures ranging from -5℃ to 40℃, curing into an excellent, durable, elastic silicone rubber by relying on moisture in the air. It provides excellent adhesion to most building materials without the need for a primer. It possesses the following superior product characteristics:

1. Easy to use: It can be squeezed out and used at any time;

2. Neutral curing: Suitable for most building materials without causing adverse reactions or corrosion;

3. Excellent adhesion: No primer is required; it can form a strong bond with most building materials.

4. Excellent weather resistance: It is not adversely affected by sunlight UV rays, rain, snow, ozone, and high and low temperatures;

5. Extremely high displacement capacity: Can withstand 100%-50% of the interface's expansion and contraction displacement.

6. After curing, it maintains good elasticity under environmental conditions of -50℃ to 150℃.
