PPG PS870C-12 (100-ml-Semkit) CORROSION RESISTANT SEALANT (100-ml-Semkit)

Additional Product Information

Overview

PS870C-12 is a high-performance corrosion inhibitive sealant designed for the aerospace industry. Its service temperature ranges from -65°F (-54°C) to 250°F (121°C), with the ability to withstand brief spikes up to 275°F (135°C). This sealant provides a robust barrier against corrosion, protecting aluminum alloys and dissimilar metals from common corrosive elements. It retains its elastomeric properties even after exposure to jet fuel and aviation gas, ensuring long-lasting durability. PS870C-12 is a two-part, manganese dioxide-cured polysulfide compound, formulated for ease of application and reliable performance.
