Re: Black Widow Ultra™ Development

Hi All,

I am brand new here but have read here and elsewhere a lot about Black Widow. Thank you for all the testing and research. Somehow I am a victim of the new AAA-F I don't know how I stuffed up in not reading it but I have mixed the new batch with the old base the Bemuda Beige. I was looking at my wall and wondering why it does not look right.

So now I know that I have to start again with a neutral grey paint and mix it with this. But what is neutral grey? The great thing about the Beige colour is that it had a NCS number which I took here in Germany to the hardware shop and they mixed it for me. What are the NCS numbers for these grey colours now. I know there are different shades depending on my taste. What is N7.5 an N8.0 for example.

I have found, reading the US and UK forums that brands and colour names don't really help as they are not available here.

Thanks guys in advance.

Edit: It looks like I might have asked a little too soon. With the help of these two threads I think i can go to the hardware store and ask for a RAL 7038

This first thread pretty much concludes to use Caporal paints but that is useless to me.

This is pretty much what I wanted. With NCS and RAL colour I am pretty sure I can get this mixed.

Re: Black Widow Ultra™ Development

Hi darbid, welcome to HTS!

Sorry you got caught in the changeover by Createx using a differently passivated aluminum in their new batches of AutoAir Aluminum. We introduced Black Widow Ultra™ as soon as possible after becoming aware of the change ourselves.

RAL Classic 7038 seems to be closer to N8 than the N7.5 of the original Black Widow™, but the RAL Classic colors don't have an N7.5 neutral gray. If you can get colors in the RAL Design colors go for a base paint in 000 75 00, but don't worry about it too much since while there is a difference in shade between N8 and N7.5 it is minor.

Re: Black Widow Ultra™ Development

Thank you harpmaker. I did get RAL7038 made up as I am tending towards lighter instead of darker. I've put on one coat directly over the failed Bermuda beige and it's looks pretty dark to me. I don't have my projector yet and I also don't have my new AAA yet so I cannot go on and test or finish. Somehow it looks much darker than your N8.0 above and what I've seen elsewhere on the net.

I would be happy to test your RAL7038 for you with my spectrometer, all you have to do is send me a 1" or larger sample to test. If you're interested PM me for the simple instructions on how to make and mail a sample to me.

It's also quite difficult to compare a reflective sample (paint) to an emmisive sample (computer screen); I just gave those samples for you to get an idea of how neutral grays compare to each other.

Thank you again. That is a lovely offer and I will take you up on that. In 1 hour as I have only just got 5 posts, or you could short cut the process and PM me the reply you would have sent.

Yes, your AAA-F with batch WDMC05-59B(01) is the old version of AAA-F and requires a PPG 'Bermuda Beige' or NCS S 0907-Y70R color base paint to come out a neutral gray. That is the standard Black Widow™ mix and it has an N value of 7.5.

Re: Black Widow Ultra™ Development

in my previous paints with BW ( both with new AA formula) i never notice any sparkle but today after giving 2 coats (need 1 more) i start my projector and on white/bright images i can see lot of sparkles, is very anoying.

this is normal and after paint dry a bit more those sparkles will disappear?

one thing i notice immediately was that the old AA formula have much more sparkles ( the shiny flakes) compared with the new AA formula i used in my previous BW paints.

this last BW mix (original) is much dark compared my previous paint ( NCS S 1500N) wich is perfect, but those sparkles are killing me.

is this normal and go away after i give one more coat and let the paint dry for 1-2 days?

Yes, the sparkles are the most visible when the paint is still wet. The visible sparkles should decrease after the paint has dried, and to a lesser extent when it has "cured" (dried for a week or so).

Most BW™ users see no (or very few) sparkles unless they are setting close to the screen (closer than ~12 feet), or they are shooting an image brighter than 16 fL.

I haven't looked at the new AAA-F under a microscope yet (lost my driver disc for the device), but it does seem that the aluminum flakes are smaller in the new AAA-F.

Re: Black Widow Ultra™ Development

hey guys... i'm the new one here

i've got a small problem... i'm currently trying with the BW but the result is not the best i think

As base paint i've took "achate grey" and mixed it up with the new AAA at 4:1 and 2:1 for testing.
But well... i think its not perfect, or is it ?

Lets have a look at


Background : 4:1 mixture
Left : pure white
Middle : 2:1 mixture
Right : 1:1 mixture

I think its "too grey" or is this normal and only because i've got the direct comparison to pure white ?


Thank you for your help guys... want to finish the BW within next 2 days...
(or i "should" finish... otherwhise the wife gets moo off ^^)

Adrian
