Parker Chomerics CHO-BOND 1018 is a nickel-plated aluminum filled, two-component electrically conductive polythioether designed for use as a fillet, gap filler and seam sealant on electrical enclosures for EMI shielding. Its nickel-plated aluminum filler provides excellent corrosion resistance against MIL-DTL-5541 Type I & Type II coated aluminum substrates which reduces maintenance costs and increases aircraft availability with minimal downtime.
Because of this, CHO-BOND 1018 is galvanically compatible with Parker Chomerics CHO-SEALĀ® 6502 nickel-aluminum filled silicone and CHO-SEAL 6503 nickel-aluminum filled fluorosilcone gaskets.
CHO-BOND 1018ās custom formulated polythioether polymer system offers excellent fluid and fuel resistance to jet fuels, de-icing solutions, hydraulic fuels and more. It is also silicone-free, removing any silicone contamination concerns while also being easily paintable ā eliminating the need and cost of an additional primer application.
Overcoat adhesion qualified with MIL-PRF-23377 Type II Class N and MIL-DTL-53022 Type II epoxy primers.
