A-silicone wash materials that are stable yet extremely free-flowing under pressure, to capture all marginal details precisely. Hydrophilic properties are affected by surfactants in the material. In contact with moisture, additives move to the surface and decrease the surface tension, resulting in an improved wettability. Optimal flowing behaviour in a wet environment. Even levelling and thixotropy which results in accurate contours. Fresh, improved colours provide a better contrast between wash and tray material and thus show a more accurate detail readability.
