Material Notes:
TRA-BOND K5NA is a three-part, ablative and thermally insulating epoxy compound used in aerospace applications. This smooth, trowellable system is specified by NASA for the Space Shuttle`s solid rocket boosters for close-out and patching of the boosters` thermal protection systems. It is also used for void filling and protecting wires, tubing and other surface protrusions on hypersonic re-entry bodies, nose cones and aircraft engines. TRA-BOND K5NA is impact resistant which makes it an excellent choice for lightweight casting requirements. TRA-BOND K5NA develops strong bonds to most all substrates. It maintains excellent dimensional stability over a wide temperature range and provides protection to weathering, ozone and moisture. Information provided by Tra-Con Inc.
