coloring delrin

(OP)
i have some white delrin gears for an exhibit i'm building.  Its white in color - is there any way to apply dye?  Dye doesn't have to permeate the material - just trying to get a different suface color.

thanks

RE: coloring delrin

It may be possible to dye it with a disperse dye.  These are available from most dye suppliers.  

Make a dispersion of the dye into water, heat to near boiling and put the parts into the heated mixture.  It may take a while.

Alternatively, coat the article with a thin layer of this dye and bake it (with ventilation).  You'll have to figure out the times and temperatures.  A hot, short stay in an IR oven might do it.

Bayer sells a product called "Aura" which is designed to color plastics after they're made.  

I don't know if any of these will work with Delrin.  Good luck.

thanks rmainer - will give it a try withthe dye...

searched the web (google & yahoo) for "aura" from bayer.  no luck at all.  before i start calling, do you have a link, or can you tell which division at bayer?  their coatings or polymer division?

thanks again, will let you know how it turns out.

RE: coloring delrin

Sorry 'bout that.  I couldn't find it either so I called Bayer and they said look at www.BayerFantasia.com  They have 4 products under that heading one of which is designed to color premolded plastics.  That is "aura".  Good luck
