Loxeal 55-04 anaerobic threadlocker 50 ml, thixotropic adhesive for medium-size metal threads, high load and corrosion protection

Loxeal 55-04 anaerobic adhesive 50 ml is a single-component, thixotropic compound designed to secure medium-size metal threads against self-loosening, unscrewing, leakage and corrosion. It cures after air is excluded from the gap between two metal surfaces, forming a strong, elastic and leak-tight bond. The product is particularly suitable where threaded joints are subjected to high loads – for example in drive systems, steel structures or flange connections using stud bolts.

Advantages and unique features

• For medium-size threads – an optimal balance between strength and the possibility of service disassembly.
• Thixotropic consistency – the adhesive does not run off the threads and fills the flanks and gaps evenly.
• High resistance to impact, vibration and temperature changes – stable joints under demanding operating conditions.
• Protects against leakage and corrosion, providing long-term tightness of threaded connections.
• Fluorescent additive – the presence of adhesive in the thread can be checked with a UV lamp.
• Single-component, solvent-free formulation – simple and economical dispensing with reduced risk of application errors.

Properties and applications

• Securing medium-size threads: bolts, studs and nuts in machines, steel structures and industrial equipment.
• Drive systems and structural parts: joints that must carry high loads and maintain defined stresses over time.
• Flange joints: fixing stud bolts where high stiffness and complete sealing are required.
• Replacement for mechanical locking devices: substitutes spring washers, lock washers and locknuts.
• Chemical resistance: once cured, the bond resists water, gases, oils, alkalis and many other chemicals.
• Material limitations: intended for metal-to-metal joints only; not recommended for equipment with pure oxygen or chlorine or for thermoplastic plastics.

Technical data

Storage recommendations

Store Loxeal 55-04 in its original, tightly closed container in a dry, cool place at temperatures between +8 and +28 °C. Protect the product from direct sunlight, high temperatures and contamination. After use, clean the bottle neck and close it immediately. Keep away from foodstuffs and out of the reach of children.

FAQ

What is Loxeal 55-04 used for?
It is an anaerobic adhesive for securing medium-size metal threads in metal-to-metal joints, particularly in drive systems, structural elements and flange connections with stud bolts where the joint is subjected to high loads.

Can joints bonded with Loxeal 55-04 be disassembled?
Yes, disassembly is possible using appropriate tools and observing safety procedures; however, due to the high strength of the adhesive, increased force or heating of the parts may be necessary.

How long does it take to cure?
Typical fixture time is 10–15 minutes, functional strength is reached after 1–3 hours and full cure after approximately 3–10 hours at room temperature.

Which materials is the product suitable for?
The adhesive is intended for metal-to-metal joints and is not recommended for equipment with pure oxygen or chlorine, nor for thermoplastic plastics where stress cracking may occur.

How should the adhesive be applied correctly?
Clean and degrease the threads, then apply a small amount of adhesive to the external threads of the bolt. For blind holes, fill the threaded hole to about one-third of its depth before inserting the fastener.
