Description
URE-FIL™ 3 is designed to be mixed with urethane resins and castable epoxies to reduce costs and enhance material properties. It is essential to thoroughly disperse the filler in the liquid rubber or resin to achieve a uniform consistency. When using large amounts of filler, first mix both parts A and B of the resin, then add the filler. This ensures a smooth mixture without lumps.
To achieve optimal results, consider using the 'double-mix and pour' technique. This method can improve the final product's quality by ensuring even distribution of the filler.
Moisture Considerations: Powder fillers can absorb moisture from the air, which may react with urethane materials, causing bubbling or foaming. If this occurs, your filler likely contains moisture.
Moisture Removal: Spread the filler on a foil-lined cookie sheet to a thickness of 0.95 cm to 1.25 cm (3/8" to 1/2"). Bake at 60°C (150°F) for 4 hours. Allow the filler to cool to room temperature before mixing.
Storage Tips: Use the filler promptly after purchase to minimize moisture absorption. After decanting, immediately replace the container lid. For long-term storage, use desiccant pouches to keep the filler dry. Replace these pouches every other time you open the container, and ensure the lid is tightly sealed.
Instructions
Mixing Instructions: Thoroughly disperse URE-FIL™ fillers in liquid rubber or resin to achieve a uniform consistency. For large concentrations, mix both parts A and B of the resin, then add the filler. Ensure there are no lumps present. The 'double-mix and pour' technique can yield better results.
Moisture Management: All powder fillers absorb atmospheric moisture, which can react with urethane materials. If bubbling or foaming occurs, the filler likely contains moisture.
Moisture Removal Process: Line a cookie sheet with foil and spread the filler evenly to a thickness of 0.95 cm to 1.25 cm (3/8" to 1/2"). Bake at 60°C (150°F) for 4 hours. Remove from oven carefully and let cool to room temperature before use.
Storage Recommendations: Use the filler quickly after purchase to prevent moisture absorption. Decant the filler and replace the lid immediately. For prolonged storage, use desiccant pouches, replacing them every other time the container is opened. Ensure the lid is secure before storing.
