Hello, I have read a lot on this but wanted some feedback on the subject.I know many use PearlEx as a main pigment,I also read of people using powder coating powder(this stuff is cheap and a ton of colors).I want to dabble in some casting during the winter so I need to start to get the material together.I was going to start with a gallon of silmar 41 from mr.fiberglass.com.Thanks everyone,Victor

Pearl-Ex is good stuff. I set my base colors with liquid/paste pigments. Then modify the base with the Pearl-Ex.

What kind of liquid/paste pigments do you use? My wife has lots of acrylics she uses for her painting, but my guess is acrylic and PR won't get along together?

Thanks,
Dale
 
I agree with Mr. Scratcher (:wink:). I set my base color with liquid/paste pigment (I prefer Mixol) then augment the color with sometimes several Pearl Ex powders. I love the Metallic sheens as well as the "Pearliness".

I don't care for Powder Coat because it's more difficult to get it thoroughly mixed. It is my personal opinion that it is not as finely grained as Pearl Ex and it needs to be dissolved as opposed to PE. And there can't possibly be more colors of Powder Coating than PE. IMHO

I realize I'm chancing a posting flurry war..... But my personal experience as well as careful research cautions the use of acrylic paints. Paints can and do have binders, water and a number of other ingredients that can interfere with the curing process.

Others will tell you to go right ahead. My vote is to stick with products that are manufactured for coloring media, not waste your time and money on products that were manufactured to stand alone.

Just my 2 sense.

Right you are TD, stay with the liquid/paste colorants made for coloring the materials you are using. I use pigments available from Surfsource(a surfing industry supply company), they are designed for use with polyester and epoxy resins. They carry transparents and opaques. However, the basic 8 or so available from US Composites are just as good. Surfsource just happens to be about a mile down the road and around the corner, so if I need some I can swing by and grab a bottle, plus they are a little cheaper without the S&H. Bear in mind a 4 oz bottle goes a long way. The liquids/pastes are mixable with each other so you can make custom colors, like light pink or dark pink, royal purple or plum, marigold or mint. While Alder (Teal )is available, it is not the same as a local football team(which can't seem to find their cumulative backsides with both hands) color Teal. So you have to mix your own to get a good base color.

Good luck and welcome to the madness. (insert maniacal, crazy laughter here)
 
Super advice, all of you! I wasn't comfy with the thought of acrylic paint. I'm going to Woodcraft this morning for Mixol. They have the colors I'm looking for anyway.

This is so fun...

Dale-

And I always recommend checking out my color library. By no means definitive, but
if you're looking to make a certain color a good place to get an idea of what
dyes/pigments will get you there and some real data on gel times.
 
Jason, that's really cool! I appreciate it very much. So far, it's about experimentation for me and your chart could at least same some time-and pigment!

Thanks again,

Dale
