Adhesives - Wettability - Determination by measurement of contact angle and surface free energy of solid surface; German version EN 828:2013
This European Standard specifies a method for the determination of the surface free energy of a solid surface by measuring the contact angle of a liquid wetting the solid surface. It allows the prediction of the ability of a particular adhesive to wet a particular adherend. It can be used to characterize surfaces intended for pre treatment, coating or bonding.
