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 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 100 grades are binder-and ethylene glycol-free pigment preparations of pourable and pumpable consistency based on nonionic and/or anionic wetting and dispersing agents. Main usage areas are paint systems based on aqueous synthetic resin dispersions.
Composition and manufacturing conditions of the individual grades vary and depend on the physical properties of the basic pigments.
Note 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 with the standard quality of the product. The test method can be received if desired.
The assessment of relative tinctorial strength, shade and purity of shade is carried out colorimetrically. With the colorimetric assessment, first the relative tinctorial strength is determined by means of adjusting the colour depth respectively weighted K/S-sum. The residual shade difference is then divided – in accordance with the CIELAB-formula (DIN 6174 ) – into the lightness-contribution △ L, shade-contribution △ H and chroma-contribution △ C. For the shade assessment, we are using △ H and for the purity of shade △ C, after tinctorial strength adjustment.
The tolerances laid down for relative tinctorial strength also △ H and △ C were determined by means of a comparative statistical assessment.
Note on 3 – Viscosity The viscosity is measured by means of rotation viscometer according test method 2/12. The viscosity is read off at shear rate D = 60 s-1.
