Features & Benefits

Product Benefits
  • Easy handling and moldability: Very good glass bonding provides excellent dry handling characteristics and minimized fiber shedding during molding process.
  • High process efficiency: Fast wetting and quick air release help reducing the labor required to roll out the part. Exceptional wet tensile strength perfectly fits wet and carrying process.
  • High performance: Optimized product design allows good surface finish and smooth surface behind gelcoat while providing the final part with exceptional tensile and flexural performances.
  • Enhanced service life: Compared to standard E-glass, Advantex® glass helps with enhanced service life in applications facing corrosion.

Storage & Handling

Storage

Unless otherwise specified, it is recommended to store glass fiber products in a cool, dry area. Ideal conditions are at a temperature between 10°C and 35°C and a relative humidity between 35% and 85%. The glass fiber products must remain in their original packaging material until the point of usage. If the storage temperature is below 15°C, it is recommended that the product be stored in the workshop, within its original packaging, at least 24 hours prior to use to help prevent condensation. The packaging is not waterproof. Be sure to protect the product from the weather and other sources of water. When stored properly, there is no known shelf life to the product, and retesting is advised after three years from the initial production date to insure optimum performance.
