Pigments covered by th
22、is European Standard can also be used in pure lime mortar. For this application see EN 459-1 and EN 459-2. Pigments for this purpose can be single pigments, blends of pigments, or blends of pigments and extenders, in powder or granular form, or aqueous preparations. Pigments typically belong to one
23、of the following classes of compounds: - synthetic or natural oxides and hydroxides of iron; - oxides of chromium, titanium and manganese; - complex inorganic pigments, for example combinations of the above mentioned metal oxides and hydroxides with cobalt, aluminium, nickel and antimony oxides and
24、hydroxides; - ultramarine pigments; - phthalocyanine blue and green; - elemental carbon (should be regarded as an inorganic pigment); - blends of the above materials (which may also include extenders). 2 Normative references The following referenced documents are indispensable for the application of
