1359 SuperFast Yellow WSR C.I.NO.:PY62 Pigment Yellow 62

There is equally little commercial interest in the calcium pigment lake P.Y.62. Its use is in the plastics industry, where it produces colors in the medium to reddishyellow range. Although its solvent resistance is only average, P.Y.62 shows better fastness to plasticizers, such as dioctyl phthalate and dioctyl adipate, and consequently exhibits good bleeding fastness in plasticized PVC. It is also thermally stable. P.Y.62 is thermally stable up to 250°C. It has a considerable effect on the shrinkage of HDPE and other partially crystalline polymers. The pigment is an equally suitable colorant for polystyrene and polyurethane and lends color to polypropylene spin dyeing products with minimal application requirements.

P.Y.62 exhibits comparably low tinctorial strength. A 0.5% pigment concentration in HDPE is necessary to produce 1/3 SD colorations (containing 1% TiO2), compared to the 0.17% pigment concentration required to afford equal depth of shade with the somewhat more reddish diarylide yellow pigment P.Y.13.
