400-590 Blow Out Resistant Oxime-cure Silicone Paste
400-590 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), 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 <15 minutes, and has a tensile strength of 200 – 300 psi after fully cured. Specially formulated to retain its physical properties even during service in extreme environmental conditions, 400-590 is a smooth, black paste that is ideal for applications that require superior bond strength and moisture resistant sealing in automotive and industrial arenas.
