VOCO Die Silicone – Cartridge 50 ML

Preparation: Insert the cartridge into a type 2 VOCO dispenser or comparable dispenser. Due to technical reasons there may be slight differences in the fill levels of the two cartridge chambers prior to initial use. In such a case, remove the cartridge cap and carefully extract material until it is delivered evenly from both openings. Then attach a type 20 mixing tip and lock with a 90° turn clockwise. The material is extruded by pressing the lever and is automatically mixed in the correct ratio. After use, do not remove the mixing tip from the cartridge. Replace the used mixing tip with a new one only immediately before the next application. When changing the mixing tips, check the openings of the cartridge to ensure that the material can flow freely. Processing: To fabricate a cavity model, or a model of an individual tooth or several teeth, first take an impression of the prepared area with an alginate. Silicones or polyethers cannot be used for this purpose. Clean and dry the impression in the usual way. Ensure all drops of moisture have been removed as these will lead to artefacts in the model and thus in the restoration. Then filltheimpressionwiththediesiliconewithintheworkingtime. Beforeuse,discardthematerial(roughlythesizeofabean) that is initially extruded from the mixing tip. Starting at the deepest point, place the material directly into the impression and fill the cavity from the bottom upwards leaving the tip immersed. When applying the material, ensure that it flows evenly to avoid air bubbles. Working time at room temperature (23 °C) is at least 30 seconds. Higher temperatures reduce and lower temperatures extend the working and setting times. The completed silicone model can be removed from the impression 4 minutes after commencement of mixing. After the material has set it is extremely hard, enabling you to start modelling the composite restoration immediately.
