Safe to use Alja-Safe™ is the world’s first alginate that does not contain crystalline silica (a known carcinogen). Alja-Safe™ is perfect for making single-use molds of the face, hands and other body parts. It captures detail better than other alginates, giving you a more accurate reproduction of your original.
Alja-Safe™ is easy to use and cures quickly. It reproduces fine detail and makes an excellent temporary mold – good for one or two reproductions of any body part. You can then cast plaster, Matrix™ NEO™ (polymer modified gypsum) or Smooth-Cast™ 300Q ultra-fast urethane resin into the mold to make a reproduction.
For making re-usable molds of any body part, use "Body Double" silicone rubber.
