Description:
The PPG PR1826B-1/2 (100-ml-Semkit) is a high-performance, rapid-curing polythioether-based sealant specifically designed for integral fuel tank and fuselage joint applications in the aviation industry. Supplied in a 100 ml (3.38 fl. oz.) Semkit cartridge, this sealant ensures precise mixing and efficient application, making it ideal for both scheduled maintenance and urgent AOG situations. Aircraft engineers and MRO ground crew rely on the PPG PR1826B-1/2 for its excellent resistance to jet fuels, aviation gas, and extreme operational temperatures ranging from −62?°C to +160?°C (−80?°F to +320?°F), with intermittent exposure up to +216?°C (420?°F). Its elastomeric properties maintain flexibility and adhesion over time, protecting critical fuel tank and fuselage components from leakage, moisture ingress, and corrosion.
Used widely by aviation engineers and MRO teams, the PPG PR1826B-1/2 (100-ml-Semkit) provides rapid cure times that reduce downtime and improve operational efficiency. Its convenient Semkit packaging makes it easy for ground crew to handle and apply during both depot and field repairs. This product is essential for maintaining aircraft airworthiness and supporting fleet readiness in both military and commercial aviation sectors.
