WACKER® STABILIZER 43
This additive is used to thicken or render non-sag those grades of the ELASTOSIL® M "46.." high-strength series which are flowable as supplied. The effect is such that, when - for example - a skin mold is being made, the silicone rubber can be applied even to inclined or vertical surfaces by brush or spatula without flowing off or sagging. The more additive added to the rubber mass, the thicker tem mass becomes. Thus, the whole range of thixotropic states can be attained, including the fully non-sag state. WACKER® STABILIZER 43 is a colorless to yellowish, cloudy, medium-viscosity liquid with a faint odor. It is exclusively used to thicken those addition-curing RTV-2 silicone rubber grades of the "ELASTOSIL® M 46 .." series which are flowable as supplied.
Data sheets
Addition of 0.3 - 0.5 wt % of WACKER® STABILIZER 43 (the exact proportion depending on the grade of rubber) confers excellent non-sag properties on the catalyzed mix, at least for layers of up to 10 mm thickness, when applied to vertical surfaces.
We recommend the following procedure for mixing in the additive as homogeneously as possible: 1. Weigh out the silicone rubber base or Component A 2. Add the required proportion of Catalyst or Component B 3. Mix the mass thoroughly 4. Weigh out and add the additive 5. Mix the mass thoroughly When small quantities of silicone rubber are processed, the additive is best added via a disposable pipette (20 drops ≈ 1 g).
