Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 4619 was prepared by Technical Committee
ISO/TC 35, Paints and varnishes.
This second edition cancels and replaces the first edition (ISO 4619:1980),
of which it constitutes an editorial revision.

Driers for paints and varnishes
1 Scope
This International Standard specifies the requirements and the corresponding test methods for driers for paints,
varnishes and related products. The requirements relate to driers in the solid or liquid form.
CAUTION — The procedures described in this International Standard are intended to be carried out by
qualified chemist or by other suitably trained and/or supervised personnel. The substances and procedures
used in this method may be injurious to health if adequate precautions are not taken. This International
Standard refers only to its technical suitability and does not absolve the user from statutory obligations
relating to health and safety.
Attention is particularly drawn to the health hazards of heavy metals which may be a constituent of driers
(e.g. cobalt, lead, cerium, zirconium, vanadium; see clauses 3, 4 and 8).

3 Definition
For the purposes of this International Standard, the following definition applies.
3.1 drier: A compound, usually a metallic soap, that is added to products drying by oxidation in order to accelerate
this process.
4 Descriptions
4.1 Solid driers
Solid driers are materials which may be manufactured in a hard, soft (highly viscous) or powder form.
4.2 Liquid driers
Liquid 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 Standard.
All these types of drier, when dissolved in solvents (normally hydrocarbons), impart specific drying properties
depending on the metal used.
4.3 Metals used
The following metals are used: cobalt, manganese, lead, zinc, calcium, cerium (or other rare earths), iron,
zirconium, vanadium, barium, 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 used
The following acids are used: fatty acids of linseed oils, tall-oil fatty acids, resinic acids, naphthenic acids,
2-ethylhexanoic acid, fatty iso-acids with 9 carbon atoms, other fatty acids with 9 to 11 carbon atoms, etc.
5 Requirements and test methods
5.1 Driers for paints shall comply with the requirement given in table 1.
5.2 Driers named according to the commercial name 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-chromatographic (GC) analysis, except in
the case of naphthenic acids.
6 Sampling
Take a representative sample of the drier to be tested, as described in ISO 842.

7 Methods of test for solid driers
During the analysis, use only reagents of recognized analytical grade and only water of at least grade 3 purity in
accordance with ISO 3696.
7.1 Appearance and consistency
Examine the sample visually for uniformity. If the consistency is specified, a method for its determination shall be
agreed between the interested parties
7.2 Colour
Dissolve 1 part by mass of the drier in 1 part by mass of white spirit or other agreed solvent and compare the colour
against an agreed sample or colour standard.

ISO 4619:1998(E)
7.3 Solubility (miscibility) in solvents, raw linseed oil or other drying media
Slowly heat, raising the temperature at a rate of 1 °C/min, 5 g of 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 solution
Allow three portions 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 for the test at 50 °C shall be able to withstand the pressure generated.
7.5 Suspended solid matter
Weigh, 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 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 suspended solid matter, as a percentage by mass, using the formula
m
× 100
m
where
m is the mass, in grams, of the test portion;
m is the mass, in grams, of the residue.
7.6 Volatile matter
Proceed 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 at this
temperature for 3 h.
7.7 Acidity or basicity
7.7.1 Principle
A 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 negative value for the acidity is obtained, the drier tested is a basic drier.
