MOLYKOTE® / DOWSIL™ DC 732
MOLYKOTE® / DOWSIL™ DC 732 Multi-Purpose Sealant is a high-performance, one-part silicone adhesive sealant designed for industrial, aerospace, and defense applications. It cures at room temperature upon exposure to moisture, forming a durable, rubber-like elastomer with excellent adhesion, flexibility, and environmental resistance.
Widely used across aviation maintenance and assembly operations, DC 732 provides long-lasting sealing and bonding performance even under extreme temperatures, vibration, and mechanical stress.
