Paint – Test method for the determination of the solids content A.1 Principle The volatile constituents of the paint are evaporated at 105 °C. The residual solids are weighed and the solids content calculated.
A.2 Apparatus a) Cooling equipment, refrigerator or water bath with thermostat at approximately + 10 °C; b) porcelain dishes with a diameter of approximately 40 mm an a high of 20 mm to 30 mm; c) analytical balance, with an accuracy of 0,001 g, with zero point correction; d) warming cupboard, with forced fresh air ventilation and flame-proof interior capable of being heated to
105 °C ± 2 °C; e) desiccator, with drying agent, e.g. silica gel. A.3 Reagents Thinner consisting of a suitable solvent / thinner as recommended by the manufacturer. A.4 Procedure A.4.1 Carry out two determinations. A.4.2 Mark porcelain plates with numbers. Record the mass of the empty plates (L) to the nearest 0,001 g. Place approximately 2 g of the paint, pre-cooled to 10 °C and homogenized, in the plate with a spoon. Weigh to the nearest 0,001 g (mass M1).
A.4.3 Place the plates containing the sample in a warming cupboard at a temperature of 105 °C ± 2 °C and store there for at least 3 h or until constant mass is reached. Constant mass is reached when, after the sample has been in the warming cupboard for a further 1,5 h, the mass loss is less than 0,2 % of the initial mass. Cool the plate to room temperature in the desiccator, and weigh to the nearest 0,001 g. SIST EN 12802:2011
Paint, thermoplastics and cold plastics –
Test method for the determination and identification of organic constituents B.1 Principle Separation of the binder, insoluble organic and inorganic constituents from the specimen by solvent extraction, centrifuging and combustion. The binder type of paints and thermoplastics is identified by IR spectra using a potassium bromide (KBr) pellet or window.
The binder type of cold plastics is identified using EN ISO 11890-2, Paints and varnishes
Determination of volatile organic compound (VOC)
Part 2: Gaschromatographic method (ISO 11890-2:2006). The inorganic constituents are kept for further IR examination (Annex C), determination of titanium dioxide (Annex D) and the glass bead content (Annex E). B.2 Apparatus a) centrifuge, high-speed, min 10 000g1);
b) centrifuge bowls, steel bowls or glass tubes, each with a capacity of 80 cm3; c) spatula; d) warming cupboard, with forced ventilation, capable of being heated to 105 °C ± 10 °C; e) rotary evaporator; f) glass flask, with a capacity of 500 ml, with ground glass neck; g) infrared spectrometer, automatically recording FTIR spectrometer, range 4000 cm-1 to 400 cm-1 with an optical resolving power better than 5 cm-1 throughout the spectral range using an ordinate with a scale of 0 % to 100 % transmission. h) analytical balance, with an accuracy of 0,001 g, with zero point correction; i) two erlenmeyer flasks of heat resistant glass, 250 ml or 300 ml capacity; j) electric muffle furnace, adjustable to 450 °C ± 25 °C; k) desiccator, with drying agent, e.g. silica gel; l) ultrasonic dissolver or similar device.
1) g equals 9,81 m x s-2. SIST EN 12802:2011
for cold plastics: ethyl acetate; acetone. B.4 Procedure B.4.1 Separation of binder Weigh the centrifuge bowls to the nearest 0,01 g (W1). Weigh a portion of approximately at least 10 g to the nearest 0,01 g together with the bowl (W2).
Place a portion of the marking material, carefully homogenized, in a centrifuge tube. Add approximately 25 ml of an appropriate solvent (see B.3). Seal the tube with a stopper and, only for thermoplastic, allow to stand overnight. After standing, stir the contents of the tube thoroughly with a spatula and centrifuge the mixture at 10 000g to 15 000g for 20 min. Decant the liquid phase into the glass flask. Thin the solid phase with a further 25 ml of solvent, stir again with the spatula, rinse and centrifuge again. Repeat the procedure three times or until the liquid supernatant is of clear colour. Use a highly volatile solvent the third time (such as acetone). Expose the centrifuge bowls containing the solid phase to the air for 5 min and dry in the warming cupboard for approximately 2 h.
Cool down the tubes in a desiccator and reweigh them to the nearest 0,01 g (W3). For dispersions do the extraction with tetrahydrofurane and centrifuge at a low speed of about 1000g, as high speeds can throw out high molecular components of the binder. B.4.2 Preparation of spectra Concentrate the solutions obtained in B.4.1 down to about 20 ml in the 500 ml glass flask in a rotary evaporator.
For recording the IR spectrum of the binder of a road marking material, use the binder solutions obtained in B.4.2. Coat the cuvette window or the potassium bromide (KBr) pellet (both referred to as 'pellet' below) evenly with a specimen of the solution. Dip a previously prepared pellet into the liquid obtained from the appropriate extraction and coat it evenly with a specimen of the solution. As the solvent evaporates, examine the pellet to make sure that the film formed on it is uniform and homogeneous. There shall be no inhomogeneity or separation. In order to remove the solvent completely, store the coated pellet in a warming cupboard at 60 °C ± 2 °C until no bands of solvent are identifiable. Place the pellet in the sample holder of the IR spectrometer and record the IR spectrum. Keep the tracing as a reference. SIST EN 12802:2011
