1-component, moisture-curing, low-modulus elastic sealant
The Sikaflex AT Facade Joint Sealant is a 1‐part, moisture curing elastic sealant based on Silane Terminated Polymers. It's especially formulated for movement and connection joints on porous and non‐porous substrates, where excellent weatherability and highest UV resistance are required. AT Facade is designed for joint sealing of movement and connection joints, porous and non-porous substrates such as concrete, brick, steel metals.
Uses
Sikaflex AT‐Facade is suitable for joint sealing of movement and connection joints between the same or different substrates i.e. for concrete, steel and other metals, brick etc.
