Ebalta Kunststoff Gmbh Silastic RTV 3120

Chemical Family
Silicones

SILASTIC™ RTV-3120 are pourable rubber bases that become firm, flexible silicone rubber when cured. There is a choice of three catalysts to select from in order to tailor your working times and cure rates.

Storage

Product should be stored at or below 32ºC (89.6ºF) in original, unopened containers.

Usage

Substrate Penetration The surface of the original should be clean and free of loose material. If necessary, and in particular with porous substrates, use a suitable release agent such as petroleum jelly or soap solution.. Mixing Thoroughly stir SILASTIC RTV-3100 Series bases before using, as filler separation may occur upon prolonged standing. Weigh the base and appropriate catalyst into a clean container, mix together until the catalyst is completely dispersed in the base. Hand or mechanical mixing can be used, but do not mix for an extended period of time or allow the temperature to exceed 35°C (95°F). With the exception of SILASTIC RTV-3110 Base, it is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. A vacuum of at least 28 inches of mercury should be held until most bubbling has ceased. After an additional 1–2 minutes under vacuum, the mix should be inspected and if free of air bubbles, can then be used. A volume increase of 3–5 times will occur on vacuum de-airing the mixtures, so a suitably large container should be chosen.
