Basic Knowledge of Adhesives (Regarding Their Properties)
Free technical materials available" Explanation of topics such as "the relationship between thixotropy, viscosity, and 'stringiness'!
In this article, we will discuss the liquid properties and cured properties of adhesives in the order of changes in their state. Liquid water changes its shape flexibly when force is applied. Water placed in a cup fills the interior shape of the cup without gaps due to gravity, and the top takes on a horizontal shape. Liquids for which the "applied force" and the "amount of deformation" are in a proportional relationship, like this water, are called Newtonian fluids. On the other hand, liquids like mayonnaise have different properties than water. Mayonnaise on a plate does not spread horizontally like water; instead, it mounds up and takes on a solid-like shape. Liquids that have the property of changing viscosity depending on the applied force, like this mayonnaise, are called thixotropic liquids. Generally, materials commonly used for adhesives are also thixotropic liquids. High thixotropic liquids behave like solids when little force is applied, and they change into a liquid like water when a large force is applied. Moreover, the higher the thixotropic nature of a liquid, the greater its ability to maintain shape. *For more detailed information, please refer to the related links.
