LOCTITE® SI 5368 is a multi-purpose acetoxy silicone material with exceptional sealing, bonding, and insulating properties. It cures at room temperature in the presence of atmospheric humidity forming a flexible, tack-free seal.
LOCTITE® SI 5368 is a specially engineered adhesive sealant formulated as a black acetoxy silicone paste with high heat tolerances, withstanding temperatures up to 250°C. It is recommended for a wide range of applications, including household electrical appliances, heat sources, electrical boxes, automotive, and aeronautical applications. It provides excellent sealing, bonding, and insulating properties with enhanced load-bearing and shock absorption capabilities.
