soyutlama

The specification defines the requirements for the composition, fiziki ozellikleri, guaj pigmentlerinin performansı ve etiketlenmesi. Pigmentler, carriers and additives are included here, including requirements for pigment identification, light fastness and consistency. This article lists some pigments that meet the light resistance requirements in this manual. Ek olarak, in order to identify other pigments that meet these requirements, instructions for test sample preparation and corresponding test methods for determining relative light resistance are given. Conditions that are not covered in this manual that affect gouettes are substrate, Çevre koşulları, depolamak, carrier, pigment, katkı maddeleri, inert gases, örnek hazırlama, coarse particles, dispersion fineness, tutarlılık, freeze-thaw stability, vesaire.
