Alja-Safe™ Acrobat

Alja-Safe™ Acrobat is a fiber reinforced "non-sag" version of original Alja-Safe™ life casting alginate. Acrobat is thicker and holds vertical surfaces allowing the user better control for making molds of the face, torso, etc. Acrobat™ reproduces perfect detail from all body surfaces and is good for making temporary molds that can be used to make highly detailed reproductions cast in wax, plaster, Matrix™ NEO™ (polymer modified gypsum), platinum cure silicone or Smooth-Cast™ 300Q ultra-fast urethane resin.

Easy To Use – Mix ratio is 1 part Alja-Safe™ Acrobat™ powder sifted into 1 part water (1:1 by volume). Working time is 5 minutes and cure time is 8 minutes, assuming a water temperature of 80° F / 27° C.

Like original Alja-Safe™, Acrobat™ is skin safe and does not contain crystalline silica (a known carcinogen).

For making re-usable molds of any body part, use Body Double™ silicone rubber.
