Shade of brown

Hi, Could anyone please confirm what shade of brown this cures to. I have rosewood doors and windows on my garage so am looking more to the darker end of the colour scale. Thanks
Asked by: Abmick71
Thank you for your enquiry. This product is mid-brown in colour i.e. not particularly light or dark.

is this suitable for sealing 110mm plastic pipe?

Asked by: Winkers
Dow 791 can be used to seal pipes - it's neutral curing, flexible, non shrinking properties are beneficial in this scenario, however, long term immersion in water and plastics such as polyethylene and polypropylene can greatly reduce adhesion. By forming a gasket seal - so that there is a mechanical pressure on the cured silicone - the performance of the seal can be improved.
