About this product
Dowsil 781 is a one-part silicone sealant supplied in a 310ml cartridge, in brown, suited to timber frames, bronze aluminium and other darker building materials. It is used for glazing applications, weather sealing of sheet cladding and general internal sealing.
The sealant offers excellent adhesion to non-porous surfaces such as glass, aluminium, painted surfaces and composite boards, along with good resistance to ageing, shrinkage, cracking and discolouring, helping maintain its colour over time.
