Industrial adhesives, greases and maintenance

Frequently asked questions — Adhesives, Greases, Maintenance

• How do I choose between a threadlocker and a structural adhesive?

  Threadlockers belong to the Adhesives - Glues family and are specifically designed for thread locking and sealing, with references such as 222 or 270 depending on the desired removability. Conversely, structural adhesives, whether two-part epoxy or MS polymers, are intended for the mechanical assembly of metal or polymer parts. The choice depends on your assembly function: securing a bolt or creating a structural bond between two components.
• Which grease should be favoured for a high-temperature environment?

  For operating conditions exceeding the limits of a standard lithium grease, which is capped at 120 °C, it is necessary to opt for specific formulations within the Lubricants - Greasing category. Lithium complex or polyurea-based greases must be selected, as they are capable of withstanding temperatures up to 160 °C. This adaptation is crucial to ensure the longevity of mechanisms subjected to high thermal stress in an industrial environment.
• Should a penetrating spray or a degreaser be used before bonding?

  To prepare surfaces before applying an adhesive from the Adhesives - Glues family, a degreaser must be used, such as a brake cleaner or a fast-evaporating solvent. Penetrating sprays, such as those containing MoS₂ or WD-40, are intended to free up corroded assemblies and leave oily residues that are incompatible with optimal adhesion. A surface free from grease is essential to ensure the performance of cyanoacrylates or epoxies.
• Which lubrication solution should be chosen for use in the food industry?

  Within the Lubricants - Greasing category, the use of NSF H1 certified products is mandatory for any application where accidental contact with foodstuffs may occur. These specific lubricants guarantee process safety while maintaining the required technical performance. The NSF H1 certification must be systematically verified on the technical data sheets of the selected greases or oils before any use on equipment in a food production area.
• How can constant lubrication be ensured on machines that are difficult to access?

  To guarantee continuous lubrication without frequent human intervention, the Lubricants - Greasing family offers automatic lubricators such as Simalube or Perma. These devices provide programmable lubrication over a period ranging from 1 to 12 months. This system is particularly suited to bearings, gears and slides located in confined areas or requiring regular preventive maintenance, thereby ensuring the reliability of critical equipment without the risk of missed servicing.
