Loctite SF 712 1.75oz Bottle

LOCTITE® SF 712™ Liquid Activator is a very low viscosity translucent cyanoacrylate activator engineered for maximum efficacy in increasing the cure speed of LOCTITE® 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 liquid activator provides a robust, rapid-curing bond on all compatible materials—including sensitive electronic plastics and board stiffeners.

Why Choose LOCTITE® SF 712™?

• Instantaneous Cure Speed: Significantly increases the curing rate of cyanoacrylate instant adhesives to maximize assembly line throughput.
• Flexible Application Methods: Can be seamlessly pre-applied to the target substrate surface or post-applied directly onto exposed adhesive beads.
• Electronics Optimized: Perfectly suited for electronic application tasks, such as securing loose wires, coils, or edge guides to printed circuit boards (PCBs).
• Tamper-Proofing Capable: Ideal for heavy-duty locking and fixing of adjustable electronic or mechanical components to ensure tamper resistance.
• Rapid Solvent Evaporation: Formulated with an isopropanol amine solvent base that flashes off cleanly 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: 1.75oz Bottle
• Storage Temperature: Optimal between 8°C and 21°C (46.4°F to 69.8°F)

Simple Application Instructions

1. Clean: For optimal results, clean all internal and external surfaces to remove soluble contaminants and let dry. (Always check plastic or coating compatibility prior to full application).
2. Apply: For Post-Activation, apply the cyanoacrylate to the parts, then apply activator over all exposed adhesive (typically one drop of activator per drop of exposed adhesive). For Surface Activation, apply a single coating via spray, brush, or dipping and let it fully evaporate.
3. Assemble: Bring the components together immediately after drying, or within 45 seconds of activator application. The cyanoacrylate formula will begin curing instantly upon contact.

Frequently Asked Questions (FAQ)

What is LOCTITE® SF 712™ used for?

LOCTITE® SF 712™ is a low-viscosity liquid activator used where increased cure speed of LOCTITE® cyanoacrylate adhesives is required. It is specifically formulated to prevent electronic components and fasteners from shifting or failing due to slow fixturing or large gaps, and is ideal for securing wires, mounting board stiffeners, and tamper-proofing components.

Can LOCTITE® SF 712™ joints be disassembled?

Disassembly depends entirely on the specific cyanoacrylate adhesive paired with the activator. Generally, cyanoacrylate bonds can be broken using a specialized nitromethane or acetone-based solvent cleaner, or by applying localized heat above 80°C (176°F) to soften the underlying polymer matrix.

Does LOCTITE® SF 712™ work on all surfaces?

Yes, it offers robust performance across a wide array of assembly materials. It is highly effective on both active board substrates (like FR-4 PCBs) as well as passive housing materials. However, because the solvent carrier can affect certain plastics or coatings, it is highly recommended to check surface compatibility before mass production use.

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

No. LOCTITE® SF 712™ is not recommended for use in pure oxygen and/or oxygen-rich systems, and it should never be selected as a sealant or activator for chlorine or other strong oxidizing materials. Additionally, liquid activator and liquid cyanoacrylate adhesive should never be mixed directly outside of a bond joint due to an intense exothermic reaction.
