Resiners AirLess Pro: Tested Tips & Best Practices for Perfect Bubble Removal

• Lower Temperatures: As temperatures drop, resin thickens, making bubble removal more difficult.
• Optimal Temperature: The best results occurred at around 25°C/77.0°F (room temperature), where bubbles were removed most efficiently.
  

2. Viscosity’s Effect on Bubble Removal

We tested epoxy resins with viscosities of 3600, 7000, 5000-6000, and 1000 at various temperatures (25°C, 20°C, 15°C, and 10°C). 

• Higher Viscosity Resins: These resins release bubbles more effectively at lower temperatures.
• Lower Viscosity Resins: Struggled with bubble removal at lower temperatures, requiring more time and effort.
  

3. The Impact of Mixing Techniques on Bubble Removal

We tested the bubble removal effectiveness at the same room temperature with different mixing operators. The results showed that varying mixing methods by different people led to various amounts of bubbles, and the bubble removal machine's effectiveness in removing bubbles varied as well.

III. Best Practices for Effective Bubble Removal

1. Mixing the Resin

Resins come in various formulations with different mixing ratios. While some resins are mixed in a 1:1 ratio, others require a 3:1 ratio. It's crucial to follow the manufacturer’s instructions carefully to achieve the correct chemical reaction and ensure proper curing. Using the incorrect ratio can result in incomplete curing and affect the effectiveness of bubble removal.

• Manual Mixing: Avoid erratic stirring or using an egg-beater style to minimize bubble formation. For high-viscosity resins, maintain a steady speed and stir in the same direction to minimize bubbles.
• Dual-Head Resin Mixer: Place the measuring cup in a mixer, starting with a slow speed and gradually increasing it. Adjust the mixing time based on the resin's amount, viscosity, and ambient temperature, until it is clear and smooth. As you get to the end of mixing, adjust the cup's position to allow the mixer paddles to mix closely against the cup walls, preventing any unmixed resin from being left behind.

2. Efficient Bubble Removal

Place mixed resin into the AirLess Pro for defoaming, adjusting the defoaming time based on resin viscosity and ambient temperature:

• At room temperature (25°C), place the mixed resin in the vacuum machine and defoam for 5/10/15 minutes based on its viscosity. 
• In cooler environments (especially below 15°C), the resin becomes thicker. Preheating Part A Epoxy Resin in warm water to 28-30°C can effectively reduce viscosity, making it easier to remove bubbles in the vacuum machine. Ensure the heating is appropriate to avoid premature curing due to excessive temperature or prolonged heating.
• For high-viscosity resins, briefly warm to 40°C (no longer than 15 seconds) to reduce bubbles. Vacuum in small amounts, not exceeding 1/3 of the container’s capacity, and use a larger, deeper container to prevent bubble overflow.

3. Pouring the Resin

Once the resin is bubble-free, pour slowly into the mold with an even flow to avoid introducing new bubbles.

IV. Usage Recommendations

For optimal performance with the AirLess Pro, keep the following in mind:

• Temperature Control: Maintain resin at around 25°C. If temperatures drop below 15°C, consider preheating the resin.
• Viscosity Selection: Use resin with a viscosity not exceeding 3600 mPa·s for the best results.
• Capacity Limitations: Use the official Resiners measuring cups, and for defoaming, keep the maximum capacity to 140ml. For higher viscosity resins, use smaller amounts, ideally under 100ml per session.
• Storage and Handling: Store resin in a temperature-controlled environment to prevent crystallization and maintain optimal viscosity.
• Crystallization Treatment: If the resin is pure and crystallizes at low temperatures, place it in the oven while still packaged, heating at 60-80°C for 30 minutes or more until it returns to its original state. Important: After heating, allow the resin to cool to room temperature before use to prevent explosive reactions. Other reasonable heating methods can also resolve crystallization, such as using a sunlamp or heating devices; these methods may take longer time.
