C.I.PY183 1352 SuperFast Yellow K2270

1352 SuperFast Yellow K2270 C.I.NO.:PY183 Pigment Yellow 183

P.Y.183   is considered a specialty product for the coloration of plastics. This monoazo yellow calcium pigment lake affords reddish, somewhat dull yellow shades with poor tinctorial strength. 1/3 SD HDPE colorations (1% TiO2) require 0.32% pigment. In such media, the pigment is thermally stable up to 300°C.

Polymer shrinkage is practically unaffected. The pigment provides very good lightfastness; 1/3 SD colorations equal step 7–8 on the Blue Scale. P.Y.183 is also recommended for other high temperature processed plastics. In ABS, for example, it is thermally stable up to 300°C.

P.Y.183 is bleed resistant in plasticized PVC, where its poor tinctorial strength is of some disadvantage. 1/3 SD samples (5% TiO2) require 1.64% pigment. Such systems provide a lightfastness which is equal to step 6 on the Blue Scale; 1/3 SD transparent colorations correspond to step 6–7 on the Blue Scale.
