Alja-Safe is a natural, crystalline silica-free, seaweed-based powder that is mixed with water to create the mold making material. Alja-Safe molds are safe and flexible for life-ca sting applications but can tear easily. Alja-Safe molds are water-based, which may result in mold shrinkage. Completed molds are temporary and should be cast into as soon as possible. Also available in a fiber reinforced "non-sag" version of the original, Alja-Safe Acrobat.Alja-Safe is a new addition to the Smooth-On family of "Life Casting" mold making materials. Alja-Safe alginate is suitable for making "temporary" molds of the face, hands and other body parts. For making re-usable molds of any body part, use "Body Double" silicone rubber.What sets Alja-Safe Apart? In addition to being an exceptional body molding material, Alja-Safe alginate does not contain free crystalline silica (a known carcinogen). Alja-Safe also 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 Ð 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.PropertiesTechnical Properties Mix Ratio by Weight 4 Parts Water : 1 Part Powder Mix Ratio by Volume 1 Part Water : 1 Part Powder Pot Life 5 minutes (80¡ F / 27¡ C) Cure Time 8 minutes Color Light Purple Mixed Viscosity Variable Documentation Technical Bulletin Show more
