FAQ

What makes Flex 80 different from other Flex Series rubbers?

🪨 Flex 80 is the hardest and most durable in the Flex Series, with higher tensile and tear strength compared to lower shore hardness options.

Is Flex 80 food-safe or skin-safe?

🚫 No, Flex 80 is not food or skin safe and should not be used for applications involving direct contact with food or skin.

Can I use Flex 80 to make flexible molds?

🛠️ Yes, but it is best suited for harder, more rigid molds. For softer, more flexible molds, consider Flex 20 or 50.

Does Flex 80 bond to other materials?

✅ Yes, it can bond to some surfaces. Always use a mold release when casting into non-silicone molds to prevent unwanted adhesion.

What is the working time of Flex 80?

⏳ You have 4 minutes of working time before it begins to gel, so plan accordingly.

How should I store my urethanes to keep them in the best condition?

❄️ Store your urethanes in a cool, dark place away from direct sunlight and high temperatures, ideally between 60°F and 75°F (15°C to 24°C). Keep the container tightly sealed to prevent moisture and air from affecting the formula. Wiping the container tops before sealing can help prevent stuck caps.

What are the best conditions for pouring and displaying urethane projects?

☀️ For the best results, pour urethanes in a well-ventilated, temperature-controlled environment with humidity below 60% to prevent defects and bubbles. Once cured, keep finished projects out of direct sunlight to prevent discoloration or degradation.
