26、 may be manufactured in a hard, soft (highly viscous) or powder form.4.2 Liquid driersLiquid driers are materials which are supplied as solutions in organic solvents, usually white spirit.NOTE Emulsifiable driers are also available, but no requirements for this type are given in this International S

27、tandard.All these types of drier, when dissolved in solvents (normally hydrocarbons), impart specific drying properties depending on the metal used.4.3 Metals usedThe following metals are used: cobalt, manganese, lead, zinc, calcium, cerium (or other rare earths), iron, zirconium, vanadium, barium,

28、aluminium, strontium, etc.NOTE In this International Standard, methods for determination of metal content are given only for those metals which are in common use.4.4 Acids usedThe following acids are used: fatty acids of linseed oils, tall-oil fatty acids, resinic acids, naphthenic acids, 2-ethylhex

29、anoic acid, fatty iso-acids with 9 carbon atoms, other fatty acids with 9 to 11 carbon atoms, etc.5 Requirements and test methods5.1 Driers for paints shall comply with the requirement given in Table 1. BSI 2011BS EN ISO 4619:2010EN ISO 4619:2010 (E)25.2 Driers named according to the commercial name

30、 of the main acid used shall contain at least 90 % of this acid, except for driers based on naphthenic acids, which shall contain at least 70 % of these acids, expressed as a percentage of the total mass of acid present.NOTE If desired, the type and content of the acids may be determined by gas-chro

31、matographic (GC) analysis, except in the case of naphthenic acids.6 SamplingTake a representative sample of the drier to be tested, as described in ISO 842.7 Methods of test for solid driersDuring the analysis, use only reagents of recognized analytical grade and only water of at least grade 3 purit

32、y in accordance with ISO 3696.7.1 Appearance and consistencyExamine the sample visually for uniformity. If the consistency is specified, a method for its determination shall be agreed between the interested parties7.2 ColourDissolve 1 part by mass of the drier in 1 part by mass of white spirit or ot

38、the drier and 20 g of an agreed solvent (or drying medium) under reflux on a sand bath, with stirring, until a homogeneous solution is obtained.Allow to cool to room temperature and examine the solution for clarity, clouding and any separation or deposit.7.4 Stability of solutionAllow three portions

39、 of the solution obtained by the method specified in 7.3 to stand for 7 days in stoppered bottles, one at each of the following temperatures:a) 0 C;b) ambient temperature;c) 50 C.After 1 day and again after 7 days, examine the solutions for clarity, clouding sedimentation or gelation.The bottle used

40、 for the test at 50 C shall be able to withstand the pressure generated.7.5 Suspended solid matterWeigh, to the nearest 0,1 g, 5 g of solid drier (or 10 g of liquid drier) into a glass flask and dissolve in (or dilute with) 100 g of white spirit or an agreed solvent. Stopper the flask allow to stand

41、 at ambient temperature for 3 days, then filter off the sediment or suspended matter using a glass filter crucible of porosity P 16 (see ISO 4793). Wash the residue on the filter with the solvent and dry it at 105 C for 3 h. Cool to ambient temperature and weigh to the nearest 1 mg.Calculate the sus

42、pended solid matter, as a percentage by mass, using the formulawhere7.6 Volatile matterProceed according to ISO 3251, taking a flat-bottomed glass of aluminium dish and a test portion of (1 0,02) g. Place the dish with the test portion in the air oven, maintained at (105 2) C. Leave it in the oven a

43、t this temperature for 3 h.7.7 Acidity or basicity7.7.1 PrincipleA solution of the drier in toluene/propan-2-ol is passed through a strong acid cation exchanger and the total acid in the eluate is determined. From the total acid determined, the acid combined with the metal is subtracted.If a negativ

44、e value for the acidity is obtained, the drier tested is a basic drier.The method is suitable for driers containing barium, calcium, cobalt, lead or zinc as metals, but is not applicable to driers containing cerium, iron, manganese or zirconium as metals.In such cases, the method shall be agreed bet

Pour 250 ml of the hydrochloric acid solution (7.7.2.4) gradually into the exchange column in order to cha

48、nge the resin into the hydrogen form. Drain off slowly, at about 1 or 2 drops/s (= 5 ml/min). When the acid has drained off completely, wash the resin successively with several 350 ml portions of water. The final washings shall not be acid to litmus paper. Then displace the water in the exchange col
