Black fast cast- who from?

[CustomCreations]

Hi,
Just spotted a post in the junkyard where someone mentions that they would have prefered black resin in a kit, instead of white.
Does anyone actually do a two part black fast cast?
I was told its only available in off white or white you see, and have only ever seen a black casting system that's more a rubber base, than a solid resin.
Id rather not add a pigment either...

Cheers for any info.

I think easyflo do a resin that you can pigment black. I swear I've seen it on one of the Brickintheyard vids on youtube.

Sorry just realised you didn't want to pigment.

Alumilite does a black resin. But most resins will take a dye.

just use the dye...

Smooth-on sells a dye for their smoothcast line. Works well, but it takes a LOT of dye to get a larger batch to go black.

Let me state that the Alumilite black is superior to any dye added resin I have attempted to mix, and I have tried tons of different brands of pigment and resins... I have never been able to match the 'pure black' color and opacity of Alumilite black resin...

The Alumilite black is BLACK and consistent throughout, between pours and even batches the color is consistent... In the end I have found it to be superior in color, as far as black resins go...

Every other resin I have tinted, is a crap shot at consistency in color, and it takes a TON of dye to get anywhere near as black as the Alumilite stuff... 1 oz of pigment in one gallon of (Smooth Cast 320) resin results in a very light gray color, 4 oz is still only a dark gray and that is a 3% pigment ratio, the max Smooth On recommends... You can get more of a Black color with Smooth Cast 325 but the opacity lacks, you end up with a black glass like opacity...

I have also experienced lots of settling with resins I have tinted, meaning they need constant stirring or else the pigment starts to settle out or separate and you will experience color swirls in the final piece... I even have this happen when mixing the two halves of the resin and pouring into the mold... This isn't the case with Alumilite black...

And in the end $ for $ the Alumilite black is honestly your best value, if consistency and ease in a black resin is your desired outcome...

Cheers-
Yes I have given up trying to pigment. The amount needed to do half decent black also weakens the resin. And you are right, it does seem to marble up once in the mold.
Ive tracked down a company in the UK offering a black resin casting system, AtlasPolymers, so I have emailed asking for a cured sample tester.
Ill let you know how it goes- it would be great to get something cast in dark black !

MPK sells black but you have to buy it in 5 gallon size kits:

i think the reason the 300 series resin from smooth-on become grey when their pigments are added is because of some sort of bleach added to the resin. I would assume that their colormatch series of resin would give better results.

Now, if they only came up with a solution for resin's reaction to moisture (besides pressure casting)............

never was able to try alumite as smooth-on is the only brand availble in the netherlands (besides wilsor....yuck). Expensive as hell too, 128 euro ($180) per gallon shipped and tax included

Not really the 320 and 325 that I have used are supposed to be their pigment friendly resins... Black is just a hard color to get to, as I said the 325 will get there but it lacks opacity...

Yeah that would be nice, it's my biggest issue now...
