Weiconlock AN 305-77 Pipe and Thread Sealing Compound is a very high quality grade of one-part anaerobic adhesive. This grade is quite thick (high viscosity) which allows it to be used on larger threads (up to M80 Ø) and smooth, fairly close fitting pipe connections. On such connections it will actually bond across gaps up to 0.5mm.
AN 305-77 Pipe and Thread Sealing Compound is yellow and cures with medium strength to create permanent, long lasting seals and bonds. It has excellent chemical resistance and will reach handling strength (approximately 35% of final cure strength) in about 15-30 minutes at room temperature.
Manufactured in Germany, this industrial quality anaerobic adhesive is widely used throughout the world for sealing and locking all kinds of industrial equipment. To allow this, it has been tested and certified for use in accordance with a number of international standards. Today, Weiconlock AN 305-77 Pipe and Thread Sealing Compound is approved by both DVGW and AGA for use in sealing gas connections and by BAM as an adhesive and sealing compound for oxygen lines.
Once cured, AN 305-77 withstands temperatures between -60°C and 150°C. This grade is also non-marking.
- Sealing and locking threaded pipes, bolts and fittings up to M80
- Permanent bonding and sealing of (semi) close fitting metallic pipe connections
- Sealing gas lines, pipes and connections (AGA and DVGW certified)
- Sealing oxygen lines
- General thread locking and sealing jobs
What do I have to do to prepare the surfaces?
Clean and dry as much as possible. Weiconlock grades will work on slightly oily surfaces but adhesion will be improved on parts that have been cleaned and degreased.
How long does it take to cure?
Full cure is expected to take about 1-3 hours at room temperature. The large range quoted here is a reflection of two things; the difference in what room temperature can mean and the fact that Weiconlock AN 302-77 will take slightly longer to cure on some surfaces than others.
All that being said, handling strength is achieved far faster. This will only take about 15-30 minutes.
What’s its pot life?
Virtually unlimited. As an anaerobic adhesive, AN 305-77 only begins to cure when it is in contact with metal and deprived of air. That means as long as the bottle is open, no curing will occur.
It also means that great care should be taken to ensure that you don’t accidently allow any metal shards or filings to find their way into the bottle. Once the lid is back on, even the smallest amount of metal will cause the whole bottle to set.
How do I store it?
None of the Weiconlock grades needs to be kept in any kind of special storage. Just try and keep them somewhere that doesn’t get direct sunlight and away from heat sources. Room temperature is fine.
