MEDIUM BLUE BRAKE - 50GR bottle

This product cures when confined and there is no air between tightly fitting metal surfaces.

TYPICAL APPLICATIONS

Formulated to lock all metric and British bolts and nuts against loosening due to vibration and to seal through threads. This product is oil tolerant and will bond parts "as received", but optimum results will be obtained with clean substrates. The thixotropic nature of the product prevents it from dripping, dripping and migrating after assembly. Typically used on mounting bolts, housing screws, etc. Protects assembled parts from corrosion.

• 15 min: Hand-tight
• 1 hour : ~50% strength
• 24 hours: 100% strength

Cure rate vs. substrate

Cure rate and strength are substrate dependent. When used on mild steel or brass components, anaerobic sealing adhesives will reach maximum strength faster than on inert materials such as stainless steel and zinc dichromate.

Cure rate versus gap size

Gap size greatly affects the cure rate of anaerobic adhesives. The gap varies with the type of mesh and the size of the fastener. The larger the gap between the threads, the slower the cure. The maximum recommended gap for this product is 0.30 mm.

Curing speed versus temperature

All cure rate figures have been established by testing at 22°C. Lower temperatures will result in slower curing. Heating the assembled parts will accelerate the cure. Activator should be used if the temperature is below 5oC. If the cure rate is too slow or the gap is very large, anaerobic activator can be used to accelerate the cure. The use of an activator can decrease the bond strength by up to 30%. Oprodis recommends testing the parts to measure this effect.

Typical environmental resistance

Heat resistance

Can be used at temperatures up to 150°C. At 130°C, the bond strength will be ~30% of its strength at 21°C.

Thermal aging

Retains ~90% of its maximum strength when heated to 100°C for 90 days, then cooled and tested at 21°C.

Chemical and Solvent Resistance

Anaerobic adhesives have excellent resistance to most oils and solvents, including motor oil, leaded gasoline, brake fluids, acetone, ethanol, propanol and water. Anaerobic adhesives and sealants are not recommended for use in pure oxygen or chlorine lines.

GENERAL INFORMATION

For safe handling of this product, consult the Product Safety Data Sheet. Anaerobic adhesives cure only in the absence of air and with activation of metal parts. The adhesive on the outside of the joint will remain uncured and can be wiped off with a cloth. Not recommended on some plastics, as stress cracking can sometimes occur. Some corrosion inhibiting chemicals neutralize the curing system in this type of anaerobic adhesive. Testing is recommended to determine if cleaning is necessary.

INSTRUCTIONS FOR USE

Make sure parts are clean, dry and free of oil and grease. Apply adhesive to all engaged surfaces. Assemble parts and allow
to cure. Wipe excess adhesive from the outside of the fitting.
The product is normally applied by hand from the bottle. Dispensing systems are available for high volume applications. Contact your
representative for advice on applying solutions.

STORAGE

Store in a cool area out of direct sunlight. Refrigeration at 5°C optimizes storage stability.
