These clear adhesive sealants from Momentive are single-component RTVs which cure quickly by reacting with atmospheric moisture to form a soft dielectric silicone rubber. These materials incorporate a newly developed crosslinking chemistry and are non-corrosive to metallic substrates. They are particularly well suited for use in electrical and electronic applications. These products differ in consistency - 60-2629 is a thixotropic paste, 60-2630 is semi-flowable, and 60-2631 is flowable. When cured, they retain their elastomeric properties throughout an operating temperature range of -55C to 200°C.
