Testing Different Ways of Dyeing Urethane

In this video we're going to test a number of different pigments, dyes, and paints to see if any of them work to color urethane rubber. Can we use these in our custom skateboard parts? Let's find out!

Surprising that the acrylic paint worked. You normally wouldn't want anything containing water mixed in with your polyurethane. It usually creates bubbles. To get consistent results when mixing small batches of resin use a scale instead of by volume. You need to do some math to work out the specific gravity and ratio for the components but often this can be found in a datasheet. Just using one cup when measuring out the parts, makes it more precise still since quite a lot can cling to a cup when pouring it resin in to another. Less great for an explanatory video though. Good work on these, it's cool to see resin being used in a functional manner. Just don't go to to far into the glittery dark side :)

Thanks for the tip! I've tried doing some mixing by weight, but I think I need a more accurate scale, so I've got some digging to do. I was a little surprised by the acrylic too, and I've been getting recommendations for other pigments to try so maybe another set of tests is in order

Came across your video for info on tinting polyurethane wood finish. One thing Im considering that you didnt try is plain old food coloring from the cake decorating aisle.

@burtreynolds3143 3 ай бұрын

I'm trying this later this week. All I could find was gel food coloring. Not sure how that differs from the regular stuff I used to see but I'm going to test it as a wood finish. both straight on the wood and mixed into oil based polyurethane. I assume the colorants are water based and that they have the glycol to help them mix with oils but I can't be sure. I guess I'll find out.

I'm trying to tint my polyurethan rubber mate grey, but i cannot succeed. I tried pigments, acrylic paint, and even graphite powder. Some acrylic seemed to tint it a bit before pouring (but I had to use a lot), but when curing it went back to dark brown, like the normal urethane. I don't know what to do :(

I used urethane resin bowling ball plug to fill in some holes and I tried the acrylic paint food coloring and both tried in size over flowing the holes had to drill out idk why it worked on yours maybe the pressure pot? The bowling ball plug colors are expensive as is the ball plug. I wonder if I should order the stuff you are using and test it out on an old bowling ball

if the ratio has to be perfect, you can't measure using the same height in a conical cup, the volume is different and in a small batch, that's amplified.

Nice video! My advice, get a gram scale (jeweller's scale), this way you can get super accurate ratios even if you do small pours. Also, my experience is that anything containing water (fabric dye, acrylic ink, acrylic paint, etc) will cause the urethane to bubble. I think the only thing that saved your acrylic paint tests in this case was the pressure pot. Some urethanes are more sensitive than others, for example I have a water clear acrylic that bubbles if you look at it skew.

Maybe the failure is due to the water soluble nature of the dyes? Don't know, but I'm fairly sure that Rit dye is water based. Interesting stuff though. And subbed too. Thanks mate.

@evanlane1690 Жыл бұрын

That's EXACTLY it. Urethane is made from a polyol and isocyanate mixed together. Isocyanate also cures when exposed to water, but in that case the polyol doesn't get consumed and the byproduct of isocyanate and water is a ton of CO2 gas, which causes bubbling or if you're using water-based dyes enough bubbles to basically become a foam. Some polyurethane foams are actually made using water as a foaming agent.

@@GoodRoads I have a question. I’m thinking of dyeing wheels a navy blue but I don’t know which color wheel would work best. Perfect scenario would be a white wheel but I don’t have. It’s either a clear yellow or clear green like a teal color. Which would get me a better navy if I dye with blue?

@GoodRoads 3 жыл бұрын

You'll be able to get a deeper blue with the amber / yellow urethanes. The urethanes that cure white are very hard to get dark colors with because whatever pigments you add to the urethane is effectively getting mixed with white. The amber color of the clear urethanes will effect the blue and pull it towards a green a little bit, but you can still get really nice results.
