FBE powder coating helps to increase corrosion resistance of the pipes and is used as the first layer in the 3-layer coating systems. Typical applications of the fusion bonded epoxy typically begin with the cleansing of the surface. The main goal at this stage is to degrease the surface and remove rust and any impurities from the surface of the pipe. After that, the pipes are heated, typically to the temperatures ranging from 180 to 240 degrees. The FBE powder is then sprayed on the pipes, usually using electrostatic application method. The charged powder evenly wraps the surface of the pipes and then turns into a solid coating, either from the residual heat or from heating the pipes again. FBE powder coatings have numerous advantages, including efficient application and limitation of waste, compared to alternative options.

L-5REN2 is an adhesive that is usually used as a second layer in the 3-layer PE and PP coatings for pipes. The product can be supplied in powder or granule form, depending on the requirements of the customer. The main goal of the adhesive is to bond together the FBE, used as a ground coating and Polyethylene or Polypropylene, as a topcoat. L-5REN2 can be applied by flat die or crosshead extrusion. Exact extrusion conditions will depend on the type of the equipment used and the size of the pipe. Typical thickness for the adhesive is 0.3 mm or greater. L-5REN2 has an outstanding durability and long-term bonding strength.

Polyethylene is often used as an anti-corrosion material in the two- or three-layer coating systems. EJ-EN8 is applied as a third coat to pipes that are used to transport gas, oil or water. EJ-EN8 can be supplied either in powder or granule form, depending on the requirement of the customer, as well as in black or other colours. The product is compatible with a wide range of products, but it is recommended to use it with EN-301A FBE and L-REN2 adhesive.
