Silicone Addition Peach 20 Set - 10 kg.
The Silicone Addition Peach 20 is a 2-component (Platinum) Poly-Addition molding silicone that cures at room temperature. The silicones are very fluid after mixing and the results provide good tensile strength.
These peach silicones are suitable for molds where the lifespan is important and a large number of castings are desired. In addition, this silicone is relatively resistant to the effects of more aggressive resins such as epoxy, polyurethane and polyester. The Silicone Addition Peach are low viscous and therefore excellent "self-deaerating". Ideal for casting molds / objects where air bubbles are undesirable.

Processing
The Silicones A Peach 20 can be easily mixed by hand or by machine. Mix the A and B component carefully and in the indicated ratio (1 part A and 1 part B). Process the mixture within the pot life and wait until it has completely hardened before demould. If necessary, you can speed up the curing process by placing the whole in an oven. Please note that in that case air bubbles have less time to escape. Even a small temperature increase will accelerate the curing process.
Note: This is an addition silicone. These silicones can be poisoned by sulfur, nitrogen, amino compounds and metal salts. If you are unsure whether the products you are using (including gloves, spatulas and cups) contain these ingredients, do a small test first. These substances are found in many latex gloves, some plastilines, lacquers and adhesives, condensation silicones, 1-component silicone sealant, natural rubbers and 3D printing material (especially stereolithography). If you still want to use this, you will have to put a protective layer of poly vinyl alcohol on the original.
Extra information
The trapping of air bubbles is best prevented by vacuuming the silicone immediately after mixing. To avoid air bubbles, stir the A and B component well but slowly without hitting air. It is best to make a “figure-8” movement. If you want to lower the Shore (hardness), you can add silicone oil. The disadvantage of oil is that it does not cross-link in the silicone, so it can sweat out over time (years), which gives a greasy layer and shrinkage.
If you do not want to pour the silicone but spatula, you can add Silicone Thixo A (note: not Silicone Thixo C!!).

Shelf life
Provided the silicone is stored cool and frost-free in closed packaging, the shelf life is at least 1 year.
Safety requirements
If you frequently work with the silicone, it is recommended to wear gloves during processing and to ventilate the room well. For safety instructions, see the safety data sheet.
