FAQ

Do I need to apply an additional UV coating if I’m using Alumilite Water Clear for headlights?

⛅ Yes, while Alumilite Water Clear includes some UV protection, an additional UV coating is recommended for applications like headlights. Prolonged exposure to direct sunlight can still cause yellowing over time, so adding a UV-protective layer will help maintain clarity and durability in high-sunlight environments.

How long does it take to cure?

⌛ Alumilite Water Clear resin takes 2-3 hour to demold at 75°F, and it reaches full cure in 5-7 days at room temperature.

How do I avoid bubbles in my casting?

🎊  Pressure casting at 30-60 psi is recommended for bubble-free results.

What should I do if the B side of the resin thickens?

🪄 Warm the thickened B side to 110-120°F to return it to normal viscosity before use.

What is the shelf life of Alumilite Water Clear?

🌟 The shelf life of Alumilite Water Clear is 3 months in an unopened container. It's recommended to use the resin within this period to maintain optimal clarity and performance 

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.

Water Clear

Resin pours excellent due to low viscosity, super easy to use. Two improvements needed. Needs to be UV stabilized, current resin will yellow a bit. Aldo, 72D hardness is a bit soft, if this could be upped to 85-88D it would be perfect.
