Welding rods consist of a core and a coating which is being produced in a co-extrusion process. Celopro® is applied to the coating and acts as a binding and plasticising agent in the extrusion process. It improves the elasticity of the extruded material and thus reduces crack formation directly after production. Celopro® also influences the shrinking process of the coating and optimises its adhesion to the rod.
Celopro® H grades with a high viscosity level are recommended for this application.
