Wiseal 905 AC — Premium Acetic Silicone Sealant
One-part acid silicone — fast cure with outstanding adhesion to glass and construction substrates
Product description
Wiseal 905 AC is a one-part acid-cure silicone that sets at room temperature with rapid cure speed, high adhesion and good compatibility across most construction substrates — including hard-to-bond surfaces like glazed sanitary ware. Cures to an elastic silicone rubber with stable performance from -50 °C to 100 °C.
Particularly suited to projects in humid environments with continuous temperature swings — aquariums, bathroom glass bonding, decorative glass partitions, and interior/exterior aluminium-glass structures.
Applications
- Large aquariums, medium and small fish tanks, glass bonding for aquariums
- Sealing joints of glass display cabinets, glass shower cabins and bathroom glass partitions
- Sealing aluminium-glass doors, windows, entry doors and interior/exterior glass walls
- Sealing ceramic, metal panels and stainless steel in industrial applications
