Loxeal 58-31 Gasketing Elastic Anaerobic Adhesive 75ml
Loxeal 58-31 is a high-performance anaerobic gasketing adhesive that cures to an elastic, flexible film, replacing solid pre-formed gaskets on flange joints. It seals against gases, water, LPG, fuels, oils and a wide range of chemicals, resists shocks and vibration, and keeps sealing from -55°C right up to +180°C. The thixotropic consistency stops the sealant migrating before or during cure, and the red adhesive fluoresces under blue light for easy inspection on the production line.
Why choose Loxeal 58-31?
- Elastic cured film accommodates joint movement while maintaining the seal
- Higher strength and faster fixture than general-purpose flange sealants
- Extended service temperature to +180°C
- Thixotropic — no running or migration on vertical flanges
- Fluorescent under blue light for quality-control checks
- Dismantles with standard tools when service is required
Typical applications
Sealing flange joints on pumps, gearboxes and differential housings where an elastic, vibration-resistant gasket and elevated temperature capability are needed — demanding automotive, transport and industrial maintenance work.
How to use
- Clean and degrease the flange faces (Loxeal Cleaner 10 recommended).
- Apply enough product to fill the joint gap completely.
- Assemble the parts and hold them in place while curing.
- Use Loxeal Activator 11 for faster cure on passive metals or at low temperatures.
- To dismantle, use normal tools (heat to +150°C/+250°C if necessary), remove cured residue mechanically and clean with acetone.
Cure times
At +25°C on steel: handling strength in 10–20 minutes, functional strength in 1–3 hours and full cure in 6–12 hours. Cure speed varies with gap, substrate and temperature.

Chemical resistance
Fully cured Loxeal 58-31 offers excellent resistance to motor oil and gearbox oil at +125°C through 1,000 hours, excellent-to-good resistance to hot 50% water/glycol mixtures, and moderate resistance to gasoline on prolonged exposure.
Important notes
- Recommended for metal surfaces — seek technical advice before applying to non-metal parts.
- Uncured adhesive can damage coatings, some plastics and elastomers, and may cause delayed stress-cracking in certain thermoplastics.
- Store cool and dry at no more than +25°C; do not refill containers with used product.
