Colour: Green

Overview:

Bond It Trade A70 Studlock Green is a high strength anaerobic adhesive designed for the permanent retention and sealing of threaded fasteners in metal-to-metal assemblies. Supplied in a 25ml bottle, it is ideal for securing studs into castings, locking through bolts and threaded plugs, and helping prevent loosening on parts exposed to constant vibration or load changes. It is commonly used in mechanical and maintenance settings where you want a long-term fixing solution that can replace techniques such as double-nutting, split pins, or spot welding in suitable applications.

The green liquid offers lubricating properties during assembly to help achieve accurate torquing and consistent installation. Once cured, A70 forms a durable, corrosion-resistant bond within the thread, and its resistance to fuels, motor oils and hydraulic fluids makes it well suited to automotive, plant, and industrial equipment work where threaded joints need to stay secure over time.

Bond It Trade A70 Studlock Green Stud Thread Lock Liquid – Key FAQs

• Is A70 Studlock removable after curing?
  A70 is designed as a permanent fixing and is not intended for later disassembly, making it suitable for studs and threaded parts you don’t plan to remove.

• Where is this studlock typically used?
  It’s used for fixing and sealing studs, plugs and through bolts into castings and similar metal assemblies, improving reliability where vibration loosening is a risk.

• Does it resist oils and fuels?
  Yes, once cured it is resistant to fuels, motor oils and hydraulic fluids, which helps maintain performance in automotive and industrial environments.

• Can it be used on oily threads?
  No. Oily or greasy surfaces should not be bonded with A70. For best performance, remove heavy contamination and work on clean parts.

• How quickly does it set and cure?
  It reaches initial strength in around 10 minutes, develops full working strength in 6–12 hours, and achieves ultimate cure after 24 hours, depending on gap and temperature.

• Is it suitable for stainless steel fixings?
  Bond strength is substantially lower on stainless steel and some grades may require an activator. Always check suitability for your specific fastener and application.

• Can it be used on plastics or rubbers?
  It is designed for metal-to-metal bonding. If used near engineering plastics or rubbers, you should test first to confirm compatibility and performance.

• Are there any systems it should not be used in?
  It’s not recommended for oxygen-rich systems and should not be used with chlorine or other strong oxidising materials due to safety and compatibility concerns.

Important Notes

• Designed for metal-to-metal threaded assemblies; best results are achieved on clean parts.

• Store upright in dry, dark conditions between +5°C and +20°C, and protect from frost and direct sunlight.

• Always read the Technical Datasheet prior to first use to ensure suitability for your application.
