Selecting the right option
Use Loctite 7452 with cyanoacrylate adhesives such as Loctite 454 Instant Adhesive Gel 20g, Loctite 438 Black Toughened Instant Adhesive 25ml or Loctite 460 Low Odour Low Bloom Instant Adhesive 25ml. For toughened acrylic adhesives use Loctite 7387 Activator 100ml instead.
Using it
Surface activation: clean and degrease first, then apply one coating by spray, brush or dipping. Let the activator evaporate fully, then apply the cyanoacrylate immediately after drying. Re-apply the activator if there is a delay.
Post-activation: apply the adhesive, then spray or drop the activator over all exposed adhesive, typically one drop of activator per drop of exposed adhesive.
Storage and handling
Store unopened and dry at 8 °C to 21 °C. Storage below 8 °C or above 28 °C can adversely affect product properties.
Limits and safety
The acetone solvent can affect certain plastics or coatings, so check all surfaces for compatibility before use. Handle as highly flammable. Read the safety data sheet before use.
