1.1 This test method describes a procedure for the measurement of contact angles of two liquids, one polar and the other nonpolar, of known surface tension on a substrate, pigment (in the form of a disk), or cured or air dried coating in order to calculate the surface properties (surface tension and its dispersion and polar components) of the solid.<\/p>\n
1.2 The total solid surface tension range that can be determined using this method is approximately 20 to 60 dynes\/cm.<\/p>\n
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n D7490-08 Standard Test Method for Measurement of the Surface Tension of Solid Coatings, Substrates and Pigments using Contact Angle Measurements<\/b><\/p>\nPDF Catalog<\/h4>\n
