SPEEDBONDER and Structural AdhesivesLoctite ® Product, Ordering and Technical InformationLoctite ® SPEEDBONDER and Structural Adhesives were developed for bonding applications requiring tensile,shear, and peel strength combined with maximum impact, stress and shock resistance. These two-part, no-mix acrylicadhesives consist of a resin and an activator. The resin component is a solvent-free, medium to high viscosity liquid.Activators are discussed following this section. SPEEDBONDER 324, 326 and 3270 and Structural Adhesives 332 and392 are specially formulated to provide an optimum balance of speed and strength with ease of application.Speaker Applications:Bonding Pole Piece to Magnet to Top PlateProduct Features & Benefits:• 100% resin, solvent-free adhesives.• Forms high strength bonds to ceramic, ferrite and steel, including dichromated and plated metals.• Two component, no-mix technology. Eliminates pot-life related waste and thickening relatedprocess variations.• Dispensable from original containers with manual, semi-automatic or fully automaticdispensing systems.• Rapid fixture at room temperature. Minimizes work-in-process and line length.• Cure speeds may be tailored with choices of activators and primers on some products.Processing Steps:1. Apply recommended activator/primer (see Activators Chart pg. 21-22) to one or both surface(s)if required. Remove any surface contamination by degreasing prior to activation for optimum results.Note: Solvent based activator/primers must be allowed to dry.2. Apply selected adhesive to the other surface.3. Join surfaces using sufficient force to spread adhesives. Secure the assembly, and allowthe adhesive to fixture before further handling.18
