BR® 623P4 is a one-part epoxy material designed for use in insert or edge filing of honeycomb structures. BR® 623P4 offers the benefit of low viscosity, making it especially suitable for hand filling of small cell size [3.2 mm (1/8 inch)] and deep section [> 25.4 mm (> 1 inch)] honeycomb core and for applications with automated pumping or dispensing equipment.
The low cured nominal density [0.60 – 0.78 g/cm3 (0.022 – 0.028 lb/in3)] 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 honeycomb panels.
