400-950 is one of our single-component, moisture-curing silicone pastes that cures to a rubber-like solid and is easily removed.
The cure mechanism is neutral (oxime), curing on exposure to moisture in room temperature air. 400-950 is a non-flowable, non-sagging low-adhesion paste ideal for creating formed-in- place gaskets where re-entry or post production disassembly is necessary. It is non-corrosive to metal substrates such as copper, aluminum, and ferrous metals (with adequate ventilation).
This ready-to-use adhesive sealant skins over in 30 – 40 minutes, and bonds to most common substrates without the use of a primer.How to Buy
