Bond-Coat

Product Description

In test after test, Bond-Coat NCC outperforms standard overmolding preparations designed to protect
hardware exposed to harsh environmental conditions. The result is a bond that can survive the most
corrosive conditions and last fi ve times longer. Developed by TRI for the U.S. Navy to fight cathodic
delamination (pre-mature bond failure) of submarine connectors, Bond-Coat NCC’s metal pretreatment
system is ideal for use in harsh environments such as industrial, sub-sea and down-hole operations.
That’s because Bond-Coat NCC firmly adheres rubbers and metals needed to survive chemical exposure
and high-pressure, extreme-temperature conditions.

Advantages of Bond-Coat NCC:

  • Creates bonds that survive harsh environments (high pressures, high temperatures chemical exposure, electrolysis)
  • Increases the bond strength of exotic materials such as Vitons®, Neoprene and polyurethane
  • Non-conductive, eliminating cathodic delamination/corrosion due to chemical or moisture penetration
  • Works with existing molds
  • Can anodized after application of Bond-Coat NCC
  • Ideal for all metallic substrates, including Inconel, titanium and aluminum

Five times the protection of standard coating solutions

In an accelerated life test simulating 15 years of corrosive and stressful conditions, metals treated
with Bond-Coat NCC signifi cantly outperformed standard primed metal. In a test developed to simulate
submarine conditions, both standard primed backshells and backshells treated with Bond-Coat NCC were
subjected to a variety of saltwater conditions, pressure changes and temperature swings. While the
standard coating degraded quickly in the first few equivalent years, the Bond-Coat NCC-coated
backshells lasted an equivalent of 15 years – five times the life of the standard shells – and lost
only 16% of their original bond strength.

BOND-COAT NCC required by the U.S. Navy

In the late 1970s, the U.S. Navy sought TRI’s help with a chronic problem: the failure of underwater
electrical connectors on submarines. The problem was cathodic delamination, which caused underwater
cable connectors to fail prematurely, sometimes in two to three years due to dissimilar metal coupling
and ensuing electrolytic reaction.

In response, TRI created Bond-Coat NCC. Applied to the connector back shell, Bond-Coat NCC prevented
cathodic delamination and extended connector life by 200%. Plus, it saved the Navy $814,400 per
submarine over the life of the connectors, even before considering savings due to improved combat
readiness. The federal government now requires Bond-Coat NCC on Navy underwater connectors and other
outboard equipment.
