The Principle Of Pearlescent Pigments
Mar 09, 2018

The excellent chemical-resistant, high-temperature-resistant properties of pearlescent pigments provide the possibility of extensive application in coatings, inks, plastics and many other fields, providing a new color system and color quality for these products.

The pearlescent pigment has low heavy metal content and accords with the relevant safety technical standard, so it can be used in food packaging and children's toys. At ambient temperature, neither acid nor alkali can erode the pearlescent pigments. Pearlescent pigments can not burn, not spontaneous combustion, non-conductive, to withstand the high temperature of 600~800℃. Pearlescent pigments can also be used in reactive coatings for radiation curing systems (electron beam curing, UV curing). The special surface chemical structure of pearlescent pigments makes it have excellent hydrophilicity, therefore, it can be applied to water-based coatings, but the lipophilic poor, so used in the organic system, there will be poor dispersion, the surface treatment of pearlescent pigments, so that it can be well applied to the organic system.
