400-195 is a non-flowable, non-sagging paste product that provides a fast tack free time and high green strength. 400-195 is one of our single-component, moisture-curing silicone pastes that cures to a low to medium modulus, rubber-like solid. This smooth paste is ideal for applications that require superior bond strength and moisture resistance. The cure mechanism is neutral (oxime), curing on exposure to moisture in room temperature air. It is non-corrosive to metal substrates such as copper, aluminum, and ferrous metals (with adequate ventilation), and offers excellent adhesion to numerous substrates including metals and plastics.

This ready-to-use adhesive sealant skins over in 4 – 7 minutes, and has a tensile strength of 150 – 200 psi after fully cured. The fast tack and early strength combine to hold the assembly together as the unit moves from station to station. Novagard fast cure products outperform slower materials in multi-step assembly applications.
