Loctite 7452 Equivalent CA Adhesive Cure Accelerator

PRODUCT DESCRIPTION Characteristics: Technology: Cyanoacrylate Activator Solvent: Acetone Active Ingredient Concentration, % 0.8 to 0.95LMS Appearance Transparent colorless to slightly: amber liquidLMS Viscosity: Very low Cure: Not applicable Application : CA adhesive cure accelerator HYBOND 7452™ is used where increased cure speed of cyanoacrylate adhesives is required. It can be either pre- or post-applied to the bond. The product is especially suited for post-application on cyanoacrylate adhesive to ensure rapid fixturing. Typical applications include securing wires or coils to PCBs, tamper-proofing adjustable components, mounting stand-offs, edge guides and board stiffeners. TYPICAL PROPERTIES Specific Gravity @ 25 °C 0.79 Viscosity @ 20 °C, mPa·s (cP) 0.3 to 0.5 Drying Time @ 20 °C, seconds ≤30 On Part Life , minutes ≤1 TYPICAL PERFORMANCE Fixture time and cure speed achieved as a result of using 7452 Activator depend on the adhesive used and the substrate bonded. Fixture Time, ISO 4587, seconds:Steel (grit blasted) using hybond ® 495™,two side activation ≤10LMS (Fixture time is defined as the time to develop a shear strength of 0.1 N/mm²) Handling precautions Activator must be handled in a manner applicable to highly flammable materials and in compliance with relevant local regulations.The solvent can affect certain plastics or coatings. It is ecommended to check all surfaces for compatibility before use. Directions for use Post Activation 1. Apply cyanoacrylate to the parts to be bonded or fixed. 2. Apply Activator over all exposed cyanoacrylate adhesive by spray or drop. (Typically use one drop of activator per drop of exposed adhesive). Surface Activation 1. Apply one coating of Activator to the area to be bonded by spray, brush or dipping. Contaminated surfaces may need special cleaning or degreasing prior to activation to remove any soluble contamination. 2. Allow HYBOND 7452™ to fully evaporate from parts prior to bonding to avoid solvent entrapment within the bond joint. 3. Apply the cyanoacrylate product immediately after drying or not more than 45- seconds thereafter. 4. Activator can be re-applied if necessary if there is a delay of more than 45- seconds between original activator and adhesive application. Storage This activator is classified as HIGHLY FLAMMABLE and must be stored in an appropriate manner in compliance with relevant regulations. Do not store near oxidising agents or combustible materials. The product is light sensitve and accordingly, translucent containers should be kept in a dark place when not in use. Store product in the unopened container in a dry location. Storage information may also be indicated on the product container labelling. Optimal Storage: 8 °C to 21 °C. Storage below 8 °C or greater than 28 °C can adversely affect product properties Material removed from containers may be contaminated during use. Do not return product to the original container. cannot assume responsibility for product which has been contaminated or stored under conditions other than those previously indicated.
