This is a premium grade, low modulus, neutral curing silicone sealant from Sika, suitable for a wide range of construction and industrial applications. It is particularly well-suited for all glazing, façade, and roofline applications. The sealant is waterproof and weather resistant, making it ideal for weather sealing and joint sealing of aluminium glazing systems, curtain walling, and preformed facade panels. It can also be used for general glazing sealing and draught proofing, including for repair work and over existing sealant, both externally and internally. Additionally, it is suitable for expansion joint sealing, sanitary sealing, sealing soft metals like lead, brass, copper, and zinc, as well as parapet and rooflines. The sealant is excellent for perimeter pointing of uPVC, aluminium, wood, and all other types of window and door frames. It is UV resistant, chemical resistant, fast curing, and virtually odourless with low dirt pick-up. With excellent primerless adhesion to most common building substrates (both porous and non-porous), it is suitable for use with glass, lead, polycarbonate, and acrylic sheets. The service temperature resistance ranges from -50°C to +150°C. Sika Plastix 22A Silicone Sealant is certified for façade, glazing, cold climate, and sanitary applications under EN15651.
