Mold Compound
#623
Heavy Brush-on Latex for Flexible Molds
Characteristics
#623 is 62% solids and can be used for plaster, polyurethane, polyester, and other plaster type materials.
Notes
Flexible molds are made by brushing on successive coats of latex until the desired thickness is attained - 1/8 inch approximately in 12 coats; 1/4" in about 20 coats. The thickness will be governed by how heavily each coat is applied. The thicker the latex is brushed on, the longer each coat will take to dry. An electric fan placed 4 to 5 feet away from the model will hasten the drying time.
Additional Details
It is best to brush the last coat of the day a little heavier so that the latex will take longer to dry, therefore keeping this coat from getting too dry so that the next coat applied in the morning will adhere.
When the mold is completed (12 to 20 coats depending on how thick you wish to make it), a plaster shell is constructed around the outside to act as a cradle, or mother mold, to support the rubber mold while pouring plaster, etc. into it.
After the latex mold is completed, allow it to dry for 7 days at room temperature, or place it in a 120°F oven or drying room for 24 hours. When thoroughly dry, make the plaster shell.

How to Use Latex Casting Compounds
Easy as one, two, three!
1. Pour the liquid latex casting compound into a CLEAN, DRY, PLASTER MOLD. Our latex compound requires no on site compounding. Just stir lightly to mix well, and start to use. Allow to set in the mold approximately 1 to 5 hours for desired build-up. The liquid level may drop due to absorption. This is normal, just top it off will additional casting compound if necessary.
2. After the allotted time, pour off the casting compound. This can be poured back into the container and can be used again (provided it has not bee contaminated). Allow for the mold to drain and dry overnight, or about 12 to 14 hours.
3. When the casting compound is dry, it can be removed from the mold. This must be done carefully in order not to rip the rubber casting. (If the mold has many detailed undercuts, a mold release is available to be used in conjunction with these products.) Allow the casting to stand for 4 to 6 days for curing. Then it is ready to receive the finishing work.
