High performance weather resistant silicone sealant
JS-2800 high-performance weather resistant silicone sealant is a single component, neutral curing, low modulus, designed specifically for weather and waterproof sealing in building curtain walls. It can be easily extruded and used at -5 ℃ -40 ℃, relying on the moisture in the air to solidify into excellent and durable elastic silicone rubber
Product features
1. Easy to use: can be squeezed out for use at any time;
2. Neutral curing: suitable for most building materials without adverse reactions or corrosive effects;
3. Excellent adhesion: can form strong adhesion with most building materials;
4. Excellent weather resistance: sunlight UV, rainwater, ice and snow, ozone, and high and low temperatures will not cause adverse effects;
5. High displacement capacity: capable of carrying ± 50% of the interface's telescopic displacement capacity;
6. Low modulus: Under 100% elongation, the modulus is less than 0.4MPa, and the force on building materials is smaller;
7. After curing, maintain good elasticity under environmental conditions of -50 ℃ -150 ℃.
