Product Description:

Dow Corning 781 Acetoxy Silicone Sealant is a one-part, silicone sealant which has excellent adhesion to a range of non-porous surfaces including glass, aluminium, painted surfaces and composite boards. Offering excellent resistance to ageing, shrinkage, cracking and discolouring, this sealant is extremely durable. It is also approved in certain countries for use in contact with potable water once cured.

HOW TO USE

SURFACE PREPARATION

Ensure that surfaces to be sealed are clean, dry, sound and free from frost, release agents, old sealants and other contaminants which could impair adhesion. All surfaces should be cleaned by wiping with a suitable solvent such as DOW CORNING R40 Universal Cleaner on a clean oil- and lint-free cloth before application of sealant.

MASKING

Areas adjacent to the joints should be masked with tape to prevent contamination of the substrates and to ensure a neat sealant line. Masking tape should be removed immediately after tooling.

PRIMING

All joint surfaces other than glass and glazed ceramics should be primed. Furthermore, for specific advice, please refer to the DOW CORNING® Primers’ Guide or contact one of Dow Corning’s Regional Service Centre for technical assistance.
