400-150 is one of our single-component, moisture-curing silicone pastes that cures to a low to medium modulus, rubber-like solid.

The cure mechanism is neutral (oxime), and this general purpose silicone cures on exposure to moisture in room temperature air. 400-150 is a non-flowable, non-sagging paste product presenting an excellent balance between rate of cure, adhesion, and physical properties. It is non-corrosive to metal substrates such as aluminum and ferrous metals (with adequate ventilation).

This ready-to-use adhesive sealant skins over in 5 – 10 minutes, and bonds to most common substrates without the use of a primer. With a lower odor than conventional acetoxy cured silicones, it is used in any area where the weather and environment needs to be sealed out.
