Alja-Safe® Skin Safe Crystalline-Silica Free Alginate! In addition to being an exceptional skin safe 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 and excellent temporary mold - good for one or two reproductions of any body part. You can then cast plaster, or Smooth-Cast® 300Q fast urethane resin into the mold to make a reproduction. NOTE - ALL SPECIFICATIONS OBTAINED USING 80°F / 23°C WATER Working time and demold time can be reduced by using warmer water. Cooler water will give a longer working time and extend the demold time. Mold Star® rubbers are easy to use platinum silicones which are mixed 1A:1B by volume (no weighing scale necessary). Mold Star® silicones feature relatively low viscosities and vacuum degassing is not required for most applications. Mold Star® silicones cure to soft, strong rubbers which are tear resistant and exhibit very low long term shrinkage. Molds made with Mold Star® will last a long time in your mold library and are good for casting wax, gypsum, resins, concrete and other materials. Cured Mold Star® rubber is heat resistant up to 450°F (232°C) and is suitable for casting low-temperature melt metal alloys. Note: THI-VEX® is NOT compatible with Mold Star® rubbers.
