Novel characterization techniques to evaluate the evolution of steelcord-skim compound adhesion
Good adhesion performance between steelcord and skim compound is becoming more critical with increasing demand for sustainability and longer tire life in the tire industry. In the past years, novel characterization techniques have been developed to study the adhesion layer build-up and evolution under humid and hot conditions. By employing these techniques to evaluate adhesion systems with a variety of steelcord and skim compounds, new adhesion mechanism understandings were gained and it enabled the development of new innovative solutions, such as ternary alloy coated steelcord, that makes it possible to remove cobalt completely from tires.
