Silicone Addition Thixo A
Silicone Addition Thixo A is a thickener for all addition-/ platinum curing silicones. Thixo allows you to thicken the otherwise fluid silicone.
Silicone Thixo A (addition-curing) is a viscous component that can be added to the pourable addition curing / platinum curing silicone, to make it thicker or even paste like. This way you can cover vertical and inclined planes without the silicone running down.
First you mix the A- and B-component of the silicone. Once this is done you can add Thixo A. Do this in steps of 0.5%, stirring continuously, until you get the thickness you need. Give each step a little time before adding more. Normally a 1% addition suffices.
Example: for 1 kg of silicone usually 10 grams Thixo A is required.
The flowability of the Thixo A is better when the temperature is higher. In winter you might place it next to the heating to make it more fluid.
Please add no more than 4% Thixo A as this may negatively affect the silicone.
Thixo increases Shore values by about 1 point and the pot life and demold time is reduced a little.
Note: This product is not a curing agent of the silicone. So you really need to mix both the A and B component before adding Thixo A.
This Thixo A works only on addition silicone, not on condensation-curing silicone like silicone condensation 20, etc.
The Thixo A is available in a 50 or 500 gram bottle. This is usually sufficient for approximately 5 kg or 25 Kg of silicone blend
Provided that the components are stored in sealed containers in a cool, frost-free place away from direct sunlight, the shelf life is at least 1 year.
Use protective gloves.
