6 fine layers of metal oxide shells form a nearly perfect encapsulation around each pigment particle which lead to unmatched resistance to light, weather and SO2. This qualifies these pigments for top industrial, automotive, 2 powder and plastic applications. The 6 fold shells around each pigment particle acts as an effective barrier against the leaching of bio available lead, thereby reducing the health‐risks of using these pigments.
The high performance line offers an optimal value in use. 3 ‐ 4 highly effective layers around the pigment core provide substantially more protection against light, weather and heat when compared with standard chromate pigments.
For only a little more money those pigments qualify as colorants for high quality plastic concentrates, industrial coatings, laminates and even entry level automotive.
Different from most of the standard chrome yellows found in the market, these pigments are protected by 2 sophisticated layers of metal oxides, which move light fastness upto 6‐7 level. These pigments are recommended wherever the utmost quality of the High Performance and Extra‐High‐Performance‐series is not necessary and where good quality must be matched with reasonable pricing.
Like all other Heubach lines our Standard Line Chrome Yellows are cowles dispersible and do not require sandmilling in order to reach optimal gloss and strength.
