JBN-5900 Single Component Neutral Ketoxime Type Curing Silicone: High Weather Resistance Sealant for Aluminum Alloy Doors and Windows
JBN-5900 is a single-component silicone sealant with neutral ketoxime type curing. It offers medium modulus, durability, and does not corrode the substrate surface. This sealant provides excellent bonding and sealing functions for most materials, making it ideal for high weather resistance aluminum alloy door and window sealing. It can be applied to the combined assembly and sealing of commonly used building materials such as glass, ceramics, fiberglass, galvanized metal surfaces, pottery, most plastic panels, non-oily wood, anodized, or painted aluminum profiles. However, it is not suitable for surfaces where the temperature exceeds 50°C or in environments completely isolated from air before curing.
Shelf life: 9 months
