A skin safe addition cure silicone that can be applied directly to the face, hands or any body parts really.
Although Alginate is also great for life casting, moulds made from alginate can only be used very few times before it begins to degrade. You can use silicone again and again.
ZA22 has the consistency of soft butter for application on vertical surfaces without dripping off so no need for the addition of thixotrope.
Cast into moulds made from ZA22 with a variety of casting materials: polyester, epoxy, polyurethane resins, and plaster, concrete or Jesmonite.
Mix ratio of 1:1 by weight (base:catalyst) and for ease of mixing the base is pink and catalyst white, simply mix until the colours are fully blended.
Apply directly to skin with no barrier necessary but of course be careful around hairs.
I used a little moisturiser on my very hairy hand in testing and was not left bald.
