Pigment Brown 41, Clariant Brown RL
Briefing
Pigment Brown 41 has very yellowish shades of brown.
When used in PVC, P.Br.41 provides medium tinctorial strength and good hiding power. The pigment is not completely fast to bleeding in plasticized PVC.
In polyolefins, P.Br.41 also exhibits medium tinctorial strength. 0.21% pigment is required to formulate 1/3 SD HDPE samples containing 1% TiO2.
Incorporated in paints, P.Br.41 exhibits equally high hiding power, which makes it a less attractive product for use in metallic finishes. Its tinctorial strength in these media is comparatively poor. However, P.Br.41 is completely fast to overcoating. The commercial grade shows considerable flocculation in various paint system.
