Loctite SF 712 0.70oz Aerosol Can

LOCTITE® SF 712 is a very low viscosity translucent cyanoacrylate activator engineered for maximum efficacy in increasing the cure speed of cyanoacrylate adhesives. This industrial-grade formula permanently accelerates bonding times, preventing costly component shifting or slow fixturing caused by large gaps or dry environmental conditions. Whether you are securing wires or mounting stand-offs, this premium surface accelerator provides a robust, rapid-curing bond on all compatible materials—including sensitive electronic plastics and board stiffeners.

Why Choose LOCTITE® SF 712 ?

• Rapid Fixturing: Significantly increases the cure speed of LOCTITE® cyanoacrylate adhesives, ensuring near-instantaneous bonding.
• Versatile Application Methods: Can be flexibly pre-applied to the surface or post-applied directly onto exposed adhesive beads.
• Electronics Optimized: Particularly well-suited for electronic assembly applications, such as securing wires, coils, or edge guides to PCBs.
• Tamper-Proofing: Ideal for heavy-duty locking and securing of adjustable components, making them tamper-proof.
• Evaporative Formulation: An isopropanol amine solvent-based carrier that flashes off quickly to eliminate solvent entrapment under the joint.

Technical Specifications

• Product Type: Cyanoacrylate Activator / Accelerator
• Strength: Not applicable (Cure Speed Enhancer)
• Color: Translucent / Transparent
• Container Size: 1.75 fl oz / 50ml (Standard Tak-Pak bottle size)
• Curing Type: Liquid Activator

Simple Application Instructions

1. Clean: For optimal results, clean all internal and external surfaces to remove soluble contaminants and let dry. Check plastic compatibility prior to application.
2. Apply: For post-activation, apply adhesive first, then add one drop of activator per drop of exposed cyanoacrylate. For surface activation, spray or brush a single coating onto the surface and allow it to fully evaporate.
3. Assemble: Bring parts together immediately (or within 45 seconds if pre-applied). The adhesive formula will begin curing instantly upon contact with the activated surface.

Frequently Asked Questions (FAQ)

What is LOCTITE® SF 712™ used for?

LOCTITE® SF 712™ is an activator designed for increasing the cure speed of cyanoacrylate instant adhesives. It is specifically formulated to prevent components from shifting during assembly and is heavily relied upon for securing wires, mounting PCB components, and tamper-proofing adjustable settings.

Can LOCTITE® SF 712™ joints be disassembled?

Disassembly depends entirely on the cyanoacrylate adhesive paired with it. Generally, cyanoacrylate bonds can be dismantled using a nitromethane or acetone-based solvent cleaner, or by applying localized heat above 80°C to soften the adhesive polymer matrix.

Does LOCTITE® SF 712™ work on all surfaces?

Yes, it offers robust performance across most common substrates. It is highly effective on both active board materials (like FR-4 PCBs) as well as passive/difficult component housings. However, because it contains an amine/isopropanol solvent base, compatibility should be tested on sensitive plastics or coating surfaces prior to production line use.

Is LOCTITE® SF 712™ safe for oxidizing or oxygen-rich systems?

No. This product is not recommended for use in pure oxygen and/or oxygen-rich systems, and it must never be selected as a treatment for chlorine or other strong oxidizing materials. Additionally, liquid activator and liquid adhesive should never be mixed directly outside of a joint due to highly exothermic reactions.
