Low modulus weather resistant silicone sealant
JS-2600 low modulus weather resistant silicone sealant is a low modulus, single component neutral curing silicone sealant designed specifically for weather resistant and waterproof sealing joints in building curtain walls that require high displacement capacity. This product does not contain solvents and is environmentally friendly. It can be easily extruded and used under a wide range of temperature conditions. It relies on moisture in the air to solidify into excellent and durable elastic silicone rubber. The JS-2600 product provides superior adhesion to most building materials without the need for primer.
Product features
1. Environmental protection products: solvent-free, PVC free, isocyanate free, non-toxic, odorless, pollution-free, and fast curing;
2. Easy to use: single component is easy to use in construction, with excellent thixotropy and extrudability, and wide applicable temperature range.
3. Good adhesion: excellent adhesion to most prefabricated building materials without primer; No pollution to porous substances.
4. Excellent weather resistance, aging performance, long-term superior tensile, compressive, and shear stress performance, while good weather resistance ensures the durability of the seal and excellent waterproofing;
5. Low modulus, high displacement capacity, capable of withstanding ± 25% joint size displacement;
6. Neutral curing, non corrosive to most building materials.
