Thread Sealant: Anaerobic Adhesives

 

Thread sealants are adhesives designed to seal thread-to-bolt connections. Maximizing the sealing and securing levels is key for these types of connections. Let's take a look at what you should know about anaerobic adhesives.

 

Types of Thread Sealants

Among the anaerobic adhesives available on the market, the following types are the most common:

• Green adhesive

• Blue adhesive

• Red adhesive

Depending on the disassembly capability, we distinguish several types of anaerobic adhesives:

• Adhesives for hard-to-dismantle threads

• Adhesives for moderately dismantlable threads

• Adhesives for dismantlable threads

Let's take a closer look at the available types.

Purple Thread Adhesive B 222

The B 222 thread adhesive is easily dismantlable. The advantage of this adhesive is that it seals the connection without damaging it. It is used at temperatures up to +150°C for connections that will need to be unscrewed.

Brown Thread Adhesive B 542

The B 542 thread adhesive is a moderately dismantlable adhesive, used at a maximum temperature of +150°C. It is applied before screwing and prevents leaks while also preventing thread connections from loosening.

Green Thread Adhesives B 270 and B 290

Among green adhesives, we can distinguish two models. They differ mainly in their function and the temperature to which they are intended.

Anaerobic Adhesive B 270 for Pins:

The B 270 green anaerobic adhesive is used for temperatures up to 180°C. Its purpose is to seal the connection by applying it to the pins before inserting the screws. It is important to note that it is a strong adhesive, classified as difficult to dismantle.

Penetrating Anaerobic Adhesive B 290:

The B 290 green anaerobic adhesive is used for temperatures up to +150°C. The main difference between this adhesive and B 270 lies in its application: B 290 penetrates the connection after it has been screwed in. It is also considered a difficult-to-dismantle adhesive.

Where to use green thread sealants?

Both B 270 and B 290 are strong adhesives, meaning they are difficult to dismantle.

B 270 is used before screwing at temperatures up to 180°C, while B 290 is used after screwing at temperatures up to 150°C.

Blue Thread Adhesive B 243

The B 243 thread adhesive is blue in color. This adhesive is moderately dismantlable, meaning the threads can be unscrewed. It is used before screwing at temperatures up to 180°C.

Red Thread Adhesives B 262 and B 271

Red anaerobic adhesives are the strongest. We have two models: B 261 and B 272.

Anaerobic Adhesive B 262:

B 262 is a red, difficult-to-dismantle adhesive. It is the most powerful among anaerobic adhesives and is used for connections at temperatures up to 150°C.

Anaerobic Adhesive B 271:

B 271 is a red adhesive used at temperatures up to 180°C. It is an upgraded version of B 272, offering one of the strongest thread connections. Red thread adhesives are the most powerful on the market. Any attempt to unscrew results in thread rupture.

What to Choose: Red or Blue Thread Adhesive?

If you plan to unscrew the connected elements in the future, it's better to choose blue thread adhesive. However, if you know that there will be no need to unscrew the connection, it's advisable to use red adhesive.

Which Thread Adhesive to Choose?

The question of which thread adhesive to choose is frequently asked by our customers. It all depends on your needs and intended use. As explained above, thread-to-metal bonding adhesives have varying bonding strengths and temperature ranges, so we answer the following questions:

Thread Adhesive for High Temperatures?

If you need an anaerobic adhesive for high temperatures, there are models for temperatures up to:

• Anaerobic adhesives for +150°C

• Anaerobic adhesives for +180°C

High-temperature adhesives are also available in various colors:

• Purple

• Brown

• Green

• Blue

• Red

Thread Adhesive for Damaged Threads?

If you already have elements with damaged or torn threads, it's best to use a red thread adhesive like B 270. However, if the thread is completely torn, the following steps should be taken:

1. Clean both elements.

2. Retap the threads.

3. Use compressed air to clear out debris.

4. Apply the appropriate thread adhesive.

5. Tighten the connection.

How to Use Thread Adhesive?

Guide for using adhesives for threaded connections:

1. Clean the surfaces to be joined with a degreaser.

2. Wipe with a clean cloth.

3. Apply anaerobic adhesive to the internal or external thread.

4. Screw in the bolt or part equipped with the bolt.

5. Wipe off excess with paper or a cloth to clean the surface.

6. Secure threaded connections using professional adhesive products!
