Adhesives can fail

In his latest work the author, Gerhard Simon, again delves into the subject of adhesives, choosing two on polyolefin basis to demonstrate his findings and insights.The first part deals with cohesion, the tests and measurements that were conducted to investigate why adhesives behave the way they do. Force, extension, temperature, all play their part but so does time. Substrates are another factor to be taken into consideration. And what is the significance of the connection between yield point and cohesion? The author even uses occurrences in nature to demonstrate adhesive properties and why they can fail. The second part deals with viscosity. Why adhesives have a solid and a liquid character and which factors influence these. Numerous equations and Figures are again used to demonstrate the results and findings. What is the significance of equilibrium of structure building and structure breakdown or entanglements with polymers? The interested reader will find answers to these questions in this work.
