This volume is consi

    21、dered 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 value obtained by this method might not be the same as that calculated on the basis of the addition of masses and volumes of

    22、 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 components, due to contraction or expansion of the resin and solvent. A second factor affecting the volume of a dry coating

    23、 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 their reaction, change into non-volatile film-building materials, i.e. amines and reactive solvents in high-build two-compone

    24、nt 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 unfilled voids between pigment particles. The porosity of the film means that this method is unsuitable.The values obtained

    25、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.

    26、e matter Part 1: Method using a coated test panel to determine non-volatile matter and to determine dry film density by the Archimedes principle1 ScopeThis part of ISO 3233 describes a procedure for determining the non-volatile matter by volume, NVV, of coating materials and related products by meas

    27、uring the density of a dried coating for any specified temperature range and period of drying or curing. 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 c

    28、alculate the spreading rate of coating materials.The method specified in this part of ISO 3233 is the 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 concen

    35、ed in air and in water (or other suitable liquid of known density), coated with the product to be tested, dried and reweighed in air and in the same liquid. From these measurements, the mass, the volume and hence the density of the dry coating are calculated. The non-volatile matter by volume is cal

    36、culated from the quotient of the density of the coating material and the density of the dry film.5 Apparatus and reagentsStandard laboratory apparatus, together with the following:5.1 Analytical balance, accurate to 0,1 mg.A single-pan balance is most convenient, and a useful modification is to repl

    38、0 mm in diameter and about 0,7 mm thick, with a small hole 2 mm to 3 mm from the edge.NOTE A stainless-steel disc has been found satisfactory but has the disadvantage of having a density much in excess of normal liquid coatings. Discs of lighter material, including plastics, for example poly(ethylen

    39、e terephthalate), are permitted provided they do not change in volume by contact with the solvents contained in the liquid coating, or during the heating and drying processes involved.5.2.2 Plate, of size (75 5) mm by (120 5) mm, with a small hole 2 mm to 3 mm from the shorter side on the longitudin

    40、al axis of the panel.Glass plates may be used as these are very flat. 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). The diameter of the wire shall not exceed 0,3 mm because of sur

    41、face tension effects.Plates of this size might be difficult to accommodate in a balance case. Smaller plates may therefore be used provided the coated area is no less than 5 600 mm2.
