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.

Features

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.

Instructions

Preparation - Store and use Alja-Safe® in a dry environment at room temperature. Alja-Safe® powder may get warm in storage/shipping during the summer months which will cause the powder/water mixture to set too fast. To remedy, store Alja-Safe® in a cool area (60°C - 70°F or 15°C - 31°C) for 24 hours before using. Alja-Safe® has a limited shelf life and should be used as soon as possible. Do not allow moisture to come into contact with unused Alja-Safe®. Use only with adequate ventilation.

Practice: Make a mold of your thumb – make a mold of something small before going on to larger models. You’ll gain a lot of experience with a small test.

Applying A Release Agent – Alja-Safe® will not stick to most surfaces. When making a mold of the head, a release preparation is recommended to prevent mechanical lock to the hair. CHOLESTEROL Brand Hair Conditioner (available at most pharmacies) can be applied to hair-covered areas prior to applying Alja-Safe®. It can be washed out of the hair easily after use.

Measuring – Alja-Safe® is mixed 1 part water to 1 part powder by volume (1 cup + 1 cup, for example). You can vary the water level somewhat to change consistency of the mixture. Less water will make Alja-Safe® thicker. More water will make the mixture thinner and easier to pour. Be careful…too much water will may result in the mixture not curing.

Water Quality – Water that has a high mineral content (calcium, phosphate, etc.) may cause any alginate to become "lumpy" or not set properly. A small-scale test is recommended prior to mixing large amounts.

Temperature Of The Water - At 80° F / 27° C, Alja-Safe® will have a working time of 8 minutes and a demold time of 10 minutes. Warmer water will cause the material to cure faster (less working time). Colder water will give a longer working time and slower demold time. For best results, sift Alja-Safe® powder into water and mix as directed.

Mixing – Alja-Safe® can be hand mixed, but best results will be obtained using a power drill with a mixer attachment. Attach a Jiffy Mixer or Turbine Mixer to a power drill and mix for one minute (depending on volume) to a gel-like consistency – smooth without any powder lumps. Jiffy mixers are available at many hardware stores. Turbine Mixers will yield the best mix and are available from Smooth-On or your Smooth-On distributor.
