Topsen 680 High-Strength 100% Silicone Adhesive & Sealant

When selecting a sealant, its composition is key to determining its performance and lifespan. Many low-cost sealants use filler oils such as white oil to reduce costs, but this creates hidden risks. A true 100% silicone sealant provides a permanent solution.
 
Choosing 100% silicone sealant means you are choosing:
 
1. Long Service Life – Resists Cracking & Shrinkage
No White Oil, No Shrinkage: Filler oils evaporate over time, causing the sealant to shrink and crack, leading to seal failure and frequent rework.
Topsen 680: Made with a 100% silicone formula, free of filler oils, ensuring stable form after curing and providing decades of durable protection.

2. Excellent Weather Resistance – Withstands Sun and Rain
Superior UV & Ozone Resistance: Maintains excellent elasticity and strength even under extreme weather conditions, without becoming brittle or powdery.
Topsen 680: Offers outstanding resistance to high and low temperatures (-40°C to 150°C), delivering consistent performance in both freezing cold and intense heat.

3. Permanent Flexibility – Reliable Dynamic Sealing
Excellent Flexibility & Adhesion: Moves freely with the thermal expansion and contraction of substrates without detaching.
Topsen 680: Boasts elongation at break of over 400%, ensuring perfect sealing even in dynamic joints.

4. Broad Compatibility – Safer Application
Non-Corrosive to Sensitive Materials: Neutral cure, safe for most construction materials without risk of harm.
Topsen 680: Can be safely used on metals, glass, marble, and more, preventing corrosion or staining issues.
