PPG PS870B-1/2 -1001 (100-ml-Semkit)

Additional Product Information

Overview

This high-performance, corrosion-inhibitive sealant is designed for aerospace applications where long-term durability and environmental resistance are critical. It provides a protective barrier against moisture ingress and galvanic corrosion, particularly on aluminium alloys and between dissimilar metals commonly found in aircraft structures.

Engineered for use in both manufacturing and MRO environments, the sealant maintains flexibility and adhesion under thermal cycling, vibration, and exposure to aviation fluids. Its formulation ensures reliable sealing performance in demanding operational conditions.
