Bonding & Sealing.
Anaerobic threadlocker, cyanoacrylate, two-component epoxy, MMA structural adhesive, MS polymer, and FIPG surface sealant: each adhesive class cures and loads differently. This section explains curing mechanisms, selection criteria, and typical applications in industrial assembly.
overview
Basics
Industrial adhesives differ primarily in their curing mechanism and resulting properties. Anaerobic adhesives cure in the absence of air upon contact with metal (screw locking, shaft-hub bonding, thread sealing, surface sealing). Cyanoacrylates (superglue) cure in seconds through exposure to atmospheric moisture and are suitable for small bonding surfaces with narrow gaps. Epoxy adhesives (1K/2K) achieve high strength and good resistance to various media. MMA and structural adhesives combine high strength with toughness and gap bridging. MS polymers and polyurethanes bond and seal with permanent elasticity. UV adhesives cure within seconds, provided UV light reaches the bond line, for example, through glass or transparent plastics. Selection criteria include material pairing, gap size, desired strength or elasticity, temperature and media resistance, curing speed, and surface preparation.

FAQ
Frequently Asked Questions
Which adhesive bonds metal without welding?
For high-strength metal bonds, two-component epoxies, MMA structural adhesives, and, for shaft-hub or threaded connections, anaerobic adhesives are suitable. The gap size, type of load (shear instead of peel), and temperature are crucial. Surface preparation significantly determines the achievable strength; we recommend a suitability test on the original substrate.
When anaerobic, when epoxy
Anaerobic for narrow metallic gaps such as screws, fits, and threads: curing requires the absence of air and metal-to-metal contact. Epoxy for structural surface bonding, even of dissimilar materials and larger gaps; for 2-component systems, the mixing ratio and pot life must be observed.
