INV-F8515 Potting filler for submarine optical fiber and cable

INV-F8515 Potting filler for submarine optical fiber and cable

INV-F8515 is a two-component elastic polyurethane compound for optical fiber, Copper cable and other cable potting filling. The product's low viscosity and long pot life form an effective water barrier. Its excellent flexibility, electrical performance and long-term stability can effectively extend the service life of the product. Especially suitable for long-term protection of electrical equipment.

Typical Features
Cure after one week at room temperature, and accelerate curing at 60°C for 18 hours or 80°C for 6 hours. The following are the test results after curing for reference:
