Face Casting with Alja-Safe® Crystalline Silica-Free Alginate

Alja-Safe® Crystalline Silice-Free Alginate is suitable for making temporary molds of the face, hands and other body parts. 

What Sets Alja-Safe® Apart?

In addition to being specifically designed for making body molds, Alja-Safe® alginate does not contain free crystalline silica, a known carcinogen. Alja-Safe® is easy to use and cures quickly. It reproduces fine detail and makes excellent temporary molds. 

You can then cast plaster, duoMatrix® NEO (polymer modified gypsum), or Smooth-Cast® 300Q ultra-fast urethane resin into the mold to make a reproduction.
