31、density and to determine the volume of a dry coating obtainable from a given volume of liquid paint. This volume is considered to be the most meaningful measure of the coverage (area of surface covered at a specified dry-film thickness per unit volume) of a paint, varnish or related product. The val

32、ue obtained by this method might not be the same as that calculated on the basis of the addition of masses and volumes of the raw materials in a formulation. The volume occupied by a combination of resin and solvent can be the same as, greater than or less than the combined volume of the separate co

33、mponents, due to contraction or expansion of the resin and solvent. A second factor affecting the volume of a dry coating formulation is the degree to which the spaces between pigment particles are filled with binder. A third factor is the use of volatile components in reactive systems that, by thei

34、r reaction, change into non-volatile film-building materials, i.e. amines and reactive solvents in high-build two-component coating materials.Above and close to the critical pigment volume concentration, the volume of a dry paint film is greater than the theoretical volume, due to an increase in unf

35、illed voids between pigment particles. The porosity of the film means that this method is unsuitable.The values obtained for the non-volatile matter by volume are dependent on the temperature and time of heating, and these conditions should be carefully considered for the material being tested.4DIN

36、EN ISO 3233-1:2013-05 EN ISO 3233-1:2013 (E) 1 ScopeThis part of ISO 3233 describes a procedure for determining the non-volatile matter by volume, NVV, of coating materials and related products by measuring the density of a dried coating for any specified temperature range and period of drying or cu

37、ring. This method determines the non-volatile matter immediately after application.Using the non-volatile matter by volume results obtained in accordance with this part of ISO 3233, it is possible to calculate the spreading rate of coating materials.The method specified in this part of ISO 3233 is t

38、he preferred method for air-drying materials. Its use for other materials still has to be tested.This part of ISO 3233 is not applicable to coating materials in which the critical pigment volume concentration is exceeded.2 Normative referencesThe following referenced documents are indispensable for

However, drilling a hole is difficult and therefore, if glass plates are used, they should preferably be suspended in a stirrup or cradle of thin wire (see Figure 2).
