Optical and surface
A dynamic analysis of liquid droplets applied on a material surface can be used to determine the performance of the surface during a later process.
The basic concept of static contact angle has been in use for some 200 years. Today’s camera technology and powerful computers has taken the original concept of static contact angles to a new level, where the dynamic interaction between a liquid droplet and a surface can be studied as a function of time.
Contact angles as a testing method have over the years moved far outside the solid surface applications for which they originally were defined. When the contact angle concept was introduced for several applications some 50 years ago, it was not commonly accepted by the industry because of difficulties in obtaining reliable correlation with experienced problems in printing, coating and gluing applications.
Today the use of dynamic contact angle and sorption as a function of time have gained wide acceptance as reliable test for applications occurring also in fractions of a second. The practical usage of contact angles and the relationship between wetting (contact angle) and sorption (penetration) can explain practical problems related to printing, gluing and coating.
