Adhesives & Sealants.
Anaerobic threadlockers, structural and instant adhesives, MS polymers, and FIPG sealants—there is a suitable system for nearly every joining task, provided you understand the curing mechanisms.
Basics
Industrial adhesives differ primarily in their curing mechanisms and resulting properties. Anaerobic adhesives cure in the absence of air between metal surfaces (screw locking, shaft-hub joints, thread sealing). Cyanoacrylates (superglue) cure in seconds through exposure to moisture and are suitable for small surfaces. Epoxies (1K/2K) offer maximum strength and chemical resistance. MMA and structural adhesives combine high strength with toughness and gap-filling capability. MS polymers and polyurethanes are permanently elastic and provide a seal. UV adhesives cure in seconds under light. Selection criteria include material compatibility, gap width, desired strength or elasticity, temperature and media resistance, and cure speed.

Frequently Asked Questions
What adhesive bonds metal without welding?
Two-component epoxies, MMA structural adhesives, and—for shaft-to-hub or threaded connections—anaerobic adhesives are suitable for high-strength metal joints. The key factors are the gap width, the type of load (shear rather than peel), and temperature.
When to use anaerobic adhesive, and when to use epoxy?
Anaerobic for tight gaps in metal, such as screws, fits, and threads; epoxy for structural bonding of surfaces, including different materials and wider gaps.
