Adhesives for automotive and workshop applications
The adhesives range at Truckstop Group covers the main product types used in commercial vehicle servicing and workshop maintenance. Threadlocking compounds prevent fasteners from vibrating loose: low-strength versions allow future disassembly; high-strength versions are for permanent fixings. Use the correct grade for the application. Applying high-strength threadlock to a fastener that will need regular removal creates unnecessary workshop time.
Gasket sealants and RTV silicone compounds are used where a physical gasket is not available or where a secondary sealant is specified alongside a paper gasket. Temperature and chemical resistance ratings vary between products. For tapes and sealing products, see the Tapes collection.
What adhesive should I use for threadlocking on HGV fasteners?
Low-strength threadlock (typically blue) for fasteners that need periodic removal, such as drain plugs and sensor fittings. High-strength threadlock (typically red) for permanent fixings or fasteners subject to severe vibration. Check the manufacturer's application guide for specific torque and diameter limits for each grade.
Can I use RTV silicone sealant on HGV engine gaskets?
RTV silicone is used as a secondary sealant on some HGV gasket applications and as a standalone sealant where a physical gasket is not available. Always check that the product's temperature and chemical resistance ratings match the application.
What surface preparation is needed before applying a structural adhesive?
The bonding surfaces must be clean, dry, and free from oil, grease, paint, and loose material. Mechanical abrasion improves adhesion on smooth surfaces. Follow the specific product instructions for mixing ratio and working time.
How long does industrial adhesive take to cure fully?
Threadlocking compounds typically achieve handling strength within 10 minutes and full cure within 24 hours at room temperature. Structural adhesives have longer cure times and require full cure before load is applied. Check the product data sheet for the specific cure schedule.
