HOW TO USE POLY LATEX FALSE FACE COMPOUND

MODEL PREPARATION:

This product must be cast into a dry, unsealed, porous plaster mold, to allow for proper curing. The suitability of other porous mold materials must be determined by the user.

CASTING PROCEDURE:

Poly Latex False Face Compound must be shaken or stirred before use. Pour into a dry, unsealed gypsum mold. Tilting or lightly vibrating the mold may be helpful in eliminating bubbles if the mold contains complex undercuts or deep details. The excess material can be immediately poured back into the container for a thin skin or allowed to stand longer for a thicker skin. A standing time of 15 minutes yields a thickness of about 3/32 inches in a No. 1 Pottery Plaster mold. Denser plasters such as Hydrocal are not as absorbent thus causing thickness to build slowly. The material is then allowed to dry in the mold for 24 hours at room temperature. Drying time can be accelerated by drying at elevated temperatures.

USING THE CASTING:

Lightly dusting the inside of the casting with talc will prevent the dry rubber from sticking to itself. Avoid exposing the casting to oils, grease, or solvents. Castings should be stored out of direct sunlight.

SAFETY:

Danger, Poly Latex False Face Compound contains ammonia and is an alkaline dispersion which may cause bums of skin and eyes. Avoid skin and eye contact. Use with adequate ventilation. In case of contact, flush eyes with plenty of water for 15 minutes and seek medical attention. Remove from skin and clothing with soap and water.

STORAGE:

Store between 50°F. Exposure to temperatures below 40°F and above 80°F may damage latex, causing irreversible coagulation. DO NOT ALLOW TO FREEZE. Storage life is at least three months from date of shipment. As latex ages beyond three months, it will not cure to as supple a rubber. Shrinkage on drying may increase and toughness of the mold will decrease.

CLEANUP:

Clean up wet latex with soap and water. Dried latex can be softened with waterless hand cleaner and washed away.
