Solvay BR® 623P4 Potting Compound
Categories: Polymer; Thermoset; Epoxy

Material Notes: Description: BR® 623P4 is a one-part epoxy material designed for use in insert or edge filling of honeycomb structures. It has been formulated to offer the benefit of low viscosity, making it especially suitable for hand filling of small cell size [1/8 inch (3.175 mm)] and deep section [> 1 inch (> 25.4 mm)] honeycomb core and for applications with automated pumping or dispensing equipment. The long working out-life of BR 623P4 at room temperature eliminates the need for cleaning out pumping equipment pipe work with solvent materials. The low cured density (0.70 g/cm2) and high mechanical performance of BR 623P4 allows for excellent specific properties in honeycomb structures. The thixotropic nature of BR 623P4 ensures that there is no slump of the potting compound when used for edge filling of honey comb panels.

Features & Benefits:

  • Low odor
  • No slump during cure
  • -67°F to 230°F (-55°C to 110°C) service temperature
  • Specific gravity of 0.70 ± 0.05
  • Co-curable with most 250°F to 350°F (121°C to 177°C) advanced composite materials
  • Flammability: Self-extinguishing
  • Smoke density: passes JAR/FAR 25.853 part V
  • Resistant to aerospace fluids and solvents
Suggested Applications:
  • Insert or edge filling of honeycomb structures
