Dowsil 781 Multi-Use Sealant Brown 310ml is a versatile, one‑part silicone sealant designed for fast cure and reliable adhesion on non‑porous surfaces such as aluminium, glass and painted substrates. It delivers high modulus protection with outstanding resistance to aging, shrinkage, cracking and discolouration, making it ideal for glazing, weather sealing, draught proofing and internal sealing tasks. The acetoxy cure formulation provides rapid tack‑free condition in about an hour and supports joint movement of +/- 20% with excellent recovery. It’s potable water compliant once cured and engineered for extreme temperatures, UV and ozone exposure, plus superior weathering. With a wide application temperature range and a ready‑to‑use consistency, it’s perfect for sports of sheet cladding, curtain walls and general one‑pack sealing projects.
