Anti-corrosion pipe compatibilizer W1L-1

  W1L-1 is a polymer material based on low density polyethylene grafted with maleic anhydride. It is made by grafting maleic anhydride molecules on the molecular chain of low density polyethylene by chemical reaction, so that the end of polyethylene has the reactive and strong polarity of maleic anhydride polar molecules. It is often used in the anticorrosive layer of oil and gas anticorrosive pipeline, and its main function is to improve the adhesive strength between PE layer and epoxy resin layer.

The role of PE compatibilizer in anti-corrosion pipeline

As shown in the figure: In the anticorrosion of oil and gas pipelines, the steel pipe is sprayed with epoxy powder after derusting and preheated, and the outer layer is extruded PE coating. After spraying, a layer of PE compatibilizer should be applied first to enhance the adhesive strength between PE and epoxy resin, so PE compatibilizer is the role of adhesive here.
