Product Name
Loctite SF 7452 Accelerator for Instant CA Adhesives-20gm (0.7oz) Spray Bottle or 1-Quart Can
Brief Description
Loctite SF 7452 is a transparent, light amber, cure-speed accelerator and excess-adhesive curer specifically designed for Loctite cyanoacrylate (instant) adhesives. It is a one-component, non-CFC solvent-based solution that significantly increases the cure speed of instant adhesives. This product is suitable for both pre- and post-application to the bond, with a particular suitability for post-application to ensure rapid fixturing.
Popular Applications & Uses
- Securing wires or coils to Printed Circuit Boards (PCBs).- Tamper-proofing adjustable components.- Mounting stand-offs, edge guides, and board stiffeners.- Increasing the cure speed of cyanoacrylate adhesives.- Curing excess adhesive to improve cosmetic appearance.- Enhancing joint strength, especially when applying thick layers of CA adhesive.- Accelerating bonds in dry climates or on difficult substrates like oily or acidic wood.- General DIY repairs, hardware, trim, kitchen cabinets, electrical, plumbing, and carpentry tasks.- Hobbies and crafts.
Industries that Commonly Use It
- LED/Electronics (for PCB assembly and component securing).- General Manufacturing (for various assembly processes requiring instant adhesive acceleration).- Cabinet & Woodworking (for faster bonding and improved finishes on wood and MDF).- Construction/Building Services (for applications in trim, cabinetry, electrical, plumbing, and carpentry).- Plastic Fabrication (due to compatibility with most plastics).- Metal Fabrication (for bonding aluminum and other metals).- Medical Device/ Prosthetics (suitable for assembly of disposable medical devices).- Prosumer (for household tasks, hobbies, and crafts).- Artist, Artisan (used by artisans, knifemakers, and hobbyists).- Government & Military (complies with MIL-A-46050C standards).- Electrical Services or Products (for securing wires and coils in electrical applications).
Special and Unique Features
- Accelerates the cure speed of Loctite cyanoacrylate/instant adhesives.- Effectively cures excess adhesive, contributing to a cleaner finish.- Helps prevent the common white discoloration (blooming) associated with instant adhesives, ensuring an improved cosmetic appearance.- Can be applied both before (pre-application) and after (post-application) the adhesive.- Especially effective for post-application to achieve rapid fixturing.- Formulated as a non-CFC solvent-based product.- Complies with military specification MIL-A-46050C.- Made with "cleanroom" grade acetone, making it suitable for the assembly of disposable medical devices.- Can enhance the final bond strength, particularly in low humidity environments or on challenging substrates.
Key Properties

Comparison Note
Loctite SF 7452 is a specialized accelerator from Henkel, formulated to optimize the performance of Loctite brand cyanoacrylate adhesives. Its key advantage includes preventing the white discoloration (blooming) often seen with instant glues, providing a superior cosmetic finish. While many generic CA accelerators exist in the market, Loctite SF 7452 stands out due to its specific formulation for Henkel's adhesives and compliance with industrial standards like MIL-A-46050C. Alternative products, such as those from Infinity Bond, aim to offer comparable performance and specifications, often at a more competitive price point for industrial applications.
