GE SilPruf SCS2003 Silicone Sealant - Black

This was recommended for boat windows by professional plastic fabricators. So far, so good.

I've used Silpruf in the past for my boat's hatches, and it did a great job. This time, the window tore out of my convertible-top and I used Silpruf to replace the window. This takes around an hour to set-up, giving enough time to get things in place and cleaned-up, which is way-different from typical silicones. This takes a very-long time to cure (like 3-days) to the point where it's solid-enough you can kind-of trust it, but it takes more than a week to cure to the point where you can put tension on it.

This works very well for mounting sinks underneath a counter top. It can be worked for at least one hour at room temperature but is non-sticky after eight hours and after a few days sets to a very resilient, rubber-like consistency. I particularly like the fact that it can be wiped off clean during installation with some tissue to achieve minimal visibility. The trick is not to use too much or it will take a while to clean up from the sink side of the joint.

They use this Silicon to attach skyscraper windows. Hopefully this time my yacht windows will not leak.

It arrived in a timely manner and the product was easy to apply. It is being used in a marine application to attach plexiglass to an aluminum frame. Since we expect this product to give a 10 year life, we cannot comment on the performance of the product at this time.

I needed a silicone product that could be stretched to twice its length and compressed to half its length repetitively over hundreds of cycles. This product meets that requirement.

Good stuff. A must have for structurally bonding safety glass films.

Very flexible caulk
