PR1861-1-OZ ADHESION PROMOTER, BOTTLE, 1 OZ, LIQUID, CLEAR

PR1861-1-OZ is a clear liquid adhesion promoter engineered to increase the bond strength of polysulfide, polyurethane and specialty aerospace sealants on metals, composite laminates and surface-treated substrates. Supplied in a 1-ounce bottle for precise application, it forms a uniform interface that enhances wetting, improves resistance to fuel, hydraulic fluids and temperature cycling, and supports long-term sealing performance in pressurized and non-pressurized areas. It is commonly used in fuel tank cavities, fuselage joints, access panels and composite structures where consistent adhesion is critical to structural integrity, leak prevention and durability in demanding aircraft assembly and maintenance environments.
