Product description

Silicone Condensation 20 (Medium Hard)

Description 

This silicone has a good fluidity and gives great detail while still remaining strong.The silicone Condensation 20  A + B is a 2-component (poly-condensation curing) castable molding silicone which cures at room temperature. Silicone C 20 -A + B are excellently suited for the casting of eg cement, plaster, wax, soap, and many other casting materials.

Note: Pot life and de-mould time are highly dependent on the mixing ratio and Humidity! By adding more than 2% silicone B (hardener) or at high humidity, the pot life and de-mould time are shorter.

Processing 
The silicone C 20 - A + B can easily be mixed by hand or by machine. Mix the A and B component carefully and in the indicated ratio (preferably 2%, you can add between 1.5-3% B comp)

Example: To 1 kg of A-Comp add preferably 20 grams of B-component. You can vary between 15 grams (1.5%) up to 30 grams (3%). Less or more will inhibit cure or alter the final properties of the rubber.

At 1.5%, the silicone will take longer to harden giving air bubbles more time to escape. With 3% B component the silicone will cure considerably faster. Process the mixture in the pot life and never take more than you can handle within pot-life. Only de-mould after a complete cure.

If you wish to make a mold by using a brush or spatula you need to add a 3rd component (0.6% -2% Thixo C). Typically 1% will do the trick. Thixo C thickens the mixture and makes it possible to set up the silicone agains vertical surfaces. Please be aware that the mold in this case must be provided with a support cap. This support cap may consist of gypsum bandages or epoxy support cover or acrylic resin with glass fibre fabric.

Durability
Provided that the silicone is kept in a sealed package and stored cool and frost-free, the shelf life is at least 1 year.

Safety
If you frequently work with the silicone is recommended to wear during processing gloves and properly ventilate the area. For safety instructions, see always the safety data sheet.
