Re: Chromium-free stain colorant

["Dr Henry" <henryb@itt.edu>]

The Hansa Yellow monoarylide pigments (e.g. C.I. Pigment

Yellow 1, Yellow 1:1, and Yellow 3) were developed as

alternatives to Pb/Cr-based inorganic pigments such as C.I. Pigment

Yellow 34 (lead chromate).  I  suggest considering these pigments.

(Thanks to Dr Harold Freeman for this info).

Subject: Chromium-free stain colorant

I am looking for an alternative to chromium-containing pigment for a water-based stain application.  the existing colorant provides a yellow tone. 

 

thanks.
