Taken from manufacturer's website: "The PMC®-121 Series urethane rubbers feature convenient one-to-one by volume mix ratios. PMC®-121/30 Dry is exceptionally strong and abrasion resistant for soft urethane mold rubbers. It does not exude oil and can be used for casting waxes, Smooth-On liquid plastics, gypsum plasters and other materials."
Some consideration about PMC 121/30 DRY safety usage. Inside the Safety Datasheet we found some important info about the list of dangerous components and what to do in emergency cases. At Paragraph 3.1:

Taken from manufacturer's website: "Mold Max™ 60 is a Shore 60A tin catalyzed silicone rubber formulated for applications requiring high heat resistance (up to 560°F/294°C). It features a low mixed viscosity and cured rubber exhibits very low linear shrinkage. Parts A & B are mixed 100A & 3B by weight. Pot life is 40 minutes and cure time is 24 hours. Applications include making foundry patterns, flat pattern reproductions and casting low-melt metal alloys such as tin and pewter."
Some consideration about Mold Max 60 safety usage. Inside the Safety Datasheet we found that this material don't have any dangerous components for the environment. Infact the Paragraph 3.1 says "No ingredients are hazardous according to Regulation 2012 OSHA Hazard Communication Standard 29 CFR 1910.1200 criteria."
