PPG Aerospace® PR-1764 Class B Black Electrically Conductive Sealant
Don’t leave your aircraft’s sensitive electrical components exposed to the elements. Provide a strong layer of protection with the use of PPG PRC-DeSoto PR-1764 Class B black electrically conductive sealant. In addition to providing a protective layer to electronics, this sealant maintains electrical continuity and provides exceptional long-term EMI and RMI production. It also works to inhibit corrosion on aluminum alloys and between dissimilar metals by withstanding the effects of aviation gasoline and jet fuel. PR-1764 is made up of a two-part, nickel-filled, manganese dioxide-cured Permapol® P-3 polythioether compound.
