first task was to read the safty instruction of the material that we are going to use
the material we have is
1- Smooth-cast 321
2- Smooth-cast 305 A & B
3- Polytek Poly 74-45 Liquid Rubber A & B
4- GRResing 550 gr
1- Smooth-cast 321
The Smooth-Cast™ 320 Series consists of ultra-low viscosity casting resins that yield virtually bubble-free off-white castings.
The Smooth-Cast™ 320 Series resins readily accept pigments and fillers (such as URE-FIL™ 3, 5 and 7 from Smooth-On).
Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents.
Applications for Smooth-Cast™ 320 Series resins include reproducing small to medium size sculptures, making prototype models,
special effect props, decorative jewelry and taxidermy (bones, antlers, teeth etc.).

Safety
Materials should be stored and used in a warm environment (73° F / 23° C). These products have a limited shelf
life and should be used as soon as possible. All liquid urethanes are moisture sensitive and will absorb atmospheric moisture.
Mixing tools and containers should be clean and made of metal, glass or plastic. Mixing should be done in a wellventilated area.
Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.
