Loctite SF 7452 Accelerator for Instant CA Adhesives-20gm (0.7oz) Spray Bottle or 1-Quart Can

Product Name: Loctite SF 7452 Accelerator for Instant CA Adhesives (Tak Pak Accelerator)

Loctite SF 7452 (formerly known as Tak Pak Accelerator 7452) is a transparent, light amber, solvent-based cure accelerator designed to increase the cure speed of Loctite cyanoacrylate (instant) adhesives. It is particularly useful for post-application to "freeze" adhesive fillets or cure adhesive squeezed out of joints, ensuring a clean cosmetic finish without the white hazing (blooming) often associated with instant glues. It can also be pre-applied to surfaces to speed up bonding on difficult-to-bond materials.

Popular Applications & Uses
- Securing wires and coils to printed circuit boards (PCBs).
- Curing adhesive fillets (the bead of glue outside the joint) instantly to prevent dripping or migration.
- Tamper-proofing adjustable components.
- Mounting stand-offs, edge guides, and board stiffeners.
- Accelerating cure on porous surfaces or in gaps where instant adhesives might otherwise cure slowly.
- Preventing "blooming" or "frosting" (white residue) on cosmetic parts.

Industries that Commonly Use It
- Electronics Manufacturing (PCB Assembly)
- General Industrial Manufacturing
- Jewelry and Cosmetic Assembly
- Loudspeaker Assembly
- MRO (Maintenance, Repair, and Operations)

Special and Unique Features
- Aggressive Cleaning Properties: The acetone solvent base cleans parts while preparing them for bonding.
- Reduces Blooming: Rapidly cures excess adhesive before it can vaporize and settle as white frost on surrounding parts.
- Pre- or Post-Application: Can be sprayed on the surface before bonding OR sprayed over the adhesive after assembly.
- Fast Fixturing: Dramatically reduces fixture time, often to seconds.
- Cosmetic Finish: Ensures clear, clean bond lines.

Key Properties
- Base: Acetone
- Color: Clear / Light Amber
- Viscosity: Very Low (0.3 - 0.5 mPa·s) - *Like water*
- Drying Time: ≤ 30 seconds (at 20°C)
- Specific Gravity: 0.79
- Flash Point: Very low (-131.8°F / -91°C) - *Highly Flammable*

Usage Instructions
- Post-Application (Curing Fillets): Apply instant adhesive to parts and assemble. Spray Loctite SF 7452 over the exposed adhesive squeeze-out. The adhesive will cure instantly.
- Pre-Application (Speed Bonding): Spray accelerator on one surface and let it dry (approx. 30 seconds). Apply adhesive to the other surface and assemble. The bond will fixture immediately.

Known backups / known substitutes for this product
- Loctite SF 712 (Isopropyl-based accelerator - slower drying but less aggressive on plastics).
- Permatex Zip Grip Accelerator.
- Vibra-Tite 621 Accelerator.
- 3M Scotch-Weld AC77.

Comparison Note
- **Loctite SF 7452 vs. SF 712:** Both are accelerators for super glue. **7452 is Acetone-based**, meaning it dries extremely fast and cleans well, but it can attack/melt sensitive plastics (like ABS or Styrene) if used heavily. **712 is Isopropanol-based**, which is safer on plastics but dries slightly slower. Use 7452 for speed and electronics; use 712 if you are worried about damaging plastic parts.
