Paints and varnishes. Wettability - Determination of the surface free energy of solid surfaces by measuring the contact angle Ingestion-build-105964 Test methods for footwear designed1 Scope This document specifies a test method to measure the contact angle for the determination of the surface free energy of a solid surface. The method can be applied for the characterization of substrates and coatings. NOTE 1 For the determination of the surface free energy of polymers and coatings, either the method in accordance with Owens, Wendt, Rabel and Kaelble or the method in accordance with Wu is used preferably. NOTE 2 The morphological
