Ultra high performance weather resistant silicone sealant
JS-2900 ultra high performance weather resistant silicone sealant is a single component, neutral curing, low modulus, designed specifically for weather and waterproof sealing in curtain walls of high-rise buildings. It can be easily extruded and used under wide temperature conditions, relying on the moisture in the air to solidify into excellent and durable elastic silicone rubber. The JS-2900 product can produce superior adhesion to most building materials without the need for primer.
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: No primer required, 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. Extremely high displacement capacity: capable of carrying interface+100% -50% expansion 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 ℃.
