How To Choose A Pipe Thread Sealant?

When choosing a pipe sealant, it is important to pay attention to its type, recommended processing materials, packaging, base in composition.

#1 Types

There are silicone (neutral and acid) and acrylic pipe sealers. The first type is a great choice for those who value versatility. It has a proven track record in sealing and sealing metal and plastic structures. The formed joint is elastic and resistant to deformation. This product is not suitable for over-painting.

The latter is suitable for those who want to obtain high-quality connections of metal products that are not subject to excessive pressure, vibration and temperature.

#2 Processing materials

Acrylic products are only suitable for metal. If you need to use a product for different materials, you’d better pay attention to the universal ones. Silicone blends meet this criterion. They work well with wood, glass, ceramics, metal and plastic, and some combinations of stone and concrete.

#3 Packaging

Packaging can be a tube or aluminum foil box. In the first case, the product is removed manually. The most comfortable to use is the ink cartridge. It is equipped with a movable bottom when the substance escapes and a special top for easy application.

#4 Base

The product can be based on silicone or acrylic polymers. Acid-based silicone is suitable for people who want to isolate in a specific area. But it should be noted that it goes into a chemical reaction with some materials (neoprene, EPDM, etc.).

The neutral type is a good choice for those who value versatility, as it sticks to virtually any surface. The acrylic polymer base is suitable for those who want maximum resistance to vibration and high pressure. Its plus point is that it does not need to provide oxygen, the minus is that it is only suitable for metal structures.

#5 Features

Basically, the sealant is suitable for both outdoor and indoor use. But there are recipes that specialize in a certain type. So, in internally processed products, supplements are used to protect the seams from corrosion, bacteria and fungi.

It is important to pay attention to the color of the liquid because if it is chosen incorrectly, the appearance of the structure can deteriorate significantly. In the case of using sealants to join pipes in difficult conditions, heat resistance, frost resistance, elasticity, resistance to vibration, UV rays and pressure are required.
