Factors influencing pigment types

Factors Influencing The Type Of Pigments Yielded In Wines... 

Weathering behavior is significantly influenced by pigments, the crosslinking system, fillers, and plasticizers. Non-pigmented CSM types under direct solar radiation for 6 -12 months can yellow and form cracks. Pigment type and concentration are important factors for CSM weathering resistance [83]. 

Obviously, all these structure-sensitive factors influence the reaction kinetics in practical applications to such systems as refractories, ceramics, cement, glass, luminescent materials, semiconductors, catalysts, and pigments. The reactivity of the raw mixes of the constituents, the effects of calcination or burning conditions, and the various types of diffusing species in the course of solid reactions influence the quality of the final product. From an industrial viewpoint the reactions in ionic solid systems have a universal importance. This is so vast a field that for an illustration of this significance an arbitrary selection is necessary. It is hoped, however, that the examples discussed will convey the impact of the reactivity of ionic solids on modern industrial processes and products. 

In cheap types of ceiling paint, carboxymethyl cellulose (CMC) is used as a thickener and binder in concentration up to 3 wt-%. As the pigments are a significant cost factor in the paint production a tendency can be observed to use as low titanium dioxide as possible. Of course these factors are influencing tremendously the preservation. As a rule of thumb it can be stated that the lower the raw material costs and the poorer the quality of raw materials the more efforts have to be put on a safe preservation system, the easier a carbohydrate based thickener is biodegradable, the more efforts have to be put on the microbiological stabilization.
