Notes to the Technical Delivery Specification
The object of this specification is to show, apart from the data given, also the test methods
used to obtain the data. The test methods can be received if desired. The test and evaluation
conditions are briefly described in the notes below. Varying results can be obtained from
this in other test media and/or under other test conditions. Please take information about
characteristic fastness values for the product (lightfastness, etc.) from the pattern cards.
These values are not subjected to routine checks.
The Colanyl grades are aqueous and binder free pigment preparations of pourable and
pumpable consistency based on non-ionic and/or anionic wetting and dispersing agents.
The Colanyl grades are used for the efficient coloration of water-based decorative paints.
Composition and manufacturing conditions of the individual grades vary and depend on
the physical properties of the basic pigments.
Notes on 2 – Coloristic Properties
Testing of the coloristic properties is carried out in accordance with the test method No. 2/1
“Testing of Colanyl Preparations”, in comparison w ith the standard quality of the product.
The assessment of relation tinting strength, hue and chroma is carried out colorimetrically.
The relative tinting strength is determined by means of the weighted K/S-sum. The residual
colour difference after strength adjustment is divided – i n accordance with the CIELAB-
formula (DIN 6174) – into the lightness contribution dL, hu e contribution dH and chroma
contribution dC. The tinting strength is given as relative tinting strength compared to the
standard. For the hue assessment, we use dH and for the chroma we use dC, both after
adjustment of the tinting strength to the standard. dL is not assessed because the value
approaches zero after tinting strength adjustment.
The volumetric tinting strength is calculated from the relative tinting strength and the
density of the preparation.
Note on 3 – Viscosisy
The viscosity is measured by means of rotation viscometer according to test method 2/12.
The viscosity value is read off at a shear rate D = 60 s-1.
