Quality control is needed to detect any possible problems early on and contract angle measurement provides an excellent tool for that.
Theta Flow is the new Attension premium optical tensiometer.
Wilhelmy plate method can be used to measure contact angle.
Plasma treatment is able to increase the wettability of most polymers. Hydrophobic recovery is often encountered which causes wettability to decrease.
Powder wettability can be measured with Washburn method or sessile drop.
Capillary action, also called capillary filling or wicking, means the spontaneous flow of liquid to fill small capillaries or pores.
Plasma treatment is an often-used process prior to coating, printing or gluing to improve the wettability of the material.
