Smooth, bubble-free models and casts are doable now! Surfactant reliably reduces surface tension on waxes and impression materials, even on polyethers (e.g. Impregum™) and alginate. The finely mist wetting agent requires no drying time and increases the flowability of plasters and investment materials. Air bubbles and rough surfaces were yesterday. Surfactant is environmentally neutral and also alcohol-free, so you can also use it for embedding pressed ceramics.
