simple Hi-Tek coating

[Tazza]

Hmmmm... ok... Talk me through your coating mixing process.

You should start with the powder.
20grams of powder to 100Mls of Acetone. It MUST be ACETONE. not thinners or any other rubbish you have lying around.
UN1090 Acetone or MEK...nothing else!!!!!
add a bullet to the mix as a rattler.

Shake like crazy..
let sit for 30 minutes to "react"
Shake like crazy and immediately suck up 6mls of the coating and squirt onto the 2.5kg of bullets to be coated.
swirl around until the bullets are coated for like 15 seconds.
Set aside to "dry"....NOTE : Dry does not mean "to the touch" Dry means all solvent has evaporated.
This is why I pre-warm my trays of bullets before baking....to make sure that the bullets are "Dry".

And then bake..
Does this look EXACTLY like your process?????????

Should the initial coat be 120ml of acetone to 20grams of powder? or do you get away with 100ml:20 grams?

[Stephen Cohen]

Tazza, the correct amount of acetone is 100mls, buy many including myself have used 120ml mix for first coat. I think a lot depends on where your doing the coating and the temp your working under. I coat in a small outside shed with a clear sheeting roof so it gets warm in there at times. I found the copper coating was the one I needed extra acetone on first coat, all others were fine as instructions said. Regards Stephen

I only use 20gms :100mls for both coats.
Never had an issue.
If it ain't broke, don't fix it.

EXACTLY! To the “T”. Brand new can of acetone from Home Depot.

I’m working inside a conditioned space, 65 F 45% relative humidity.

Last bullets I did were coated the day before and they were pre-warmed on top of the oven.

I’m stumped.

Please make contact with Donnie. He and I discussed your problem. He has another option.

Good to know i can do away with the initial watered down coat.

Stephen: I coat in an outside covered area, it's open on the sides, so it doesn't get stupidly hot during our nasty summers like yours would. Yet i sure can work up a sweat when doing a large batch, almost no need to go to the gym that day when doing big batches. Sadly i have a few hundred kgs worth i need to coat then size..... with the wet weather we have been having, i haven't done anything just in case it messed with bonding with the high humidity

I sent Donnie an email about this and gave him all the details about what I have been dealing with. He said he has not tested this specific batch of blue and can look at it in a week or so. He’s great to deal with and even offered me another color to make up for the problem. Hopefully we’ll get to the bottom of this soon.

Sounds like if we could hit 180C in three to four minutes hold it for two minutes and immediately remove they would be blue. And according to Joe 180C bullet temp for two minutes they should pass wipe test. What do you think?

This is how I did. Well,it takes me five minutes to hit 180 but I'm staying at 180-185 surface temp 2.30 min then.

My probe meter starts beeping @ 170°C inside temp, then my surface is 182°C. I verify with IR every 30 secs after beep,my temps go higher unless I open the door to take measurements. It's like five seconds open every 30 sec. A manual PID.



Like I posted,recovered TruBlu bullets have coating on grooves.

I'm getting blue bullets with the Tru Blue from Donnie. If my phone would upload the photo to my backup I'd post the photo.

I know what you mean. All I get is upload of file failed.

I have given up trying to upload any photos. I get answers to the effect, "file too large" or "unable to upload".
I am just no good at this technical stuff of uploading pictures.

Some times it works, others it doesn't, I can't remember if i tried uploading direct from my pc or if i had them hosted on the internet or not. I generally just email pictures, that way i know they work.

Maybe it has something to do with the make over on the site.

I have been trying for years and since I joined this site. Any uploads should work seamlessly if pictures are in a Jpeg mode. From what I was told, the "system" should automatically adjust uploads to allow posting. I don't know how that works. The uploading of pictures and videos, is already established on the system, but using it is a mystery?
May be site controllers can suggest a way to use these facilities.
Thank you in advance....

I don’t have picture problems on the tablet. I remember it being harder years ago.

[RydForLyf]

Back to my blue bullet challenge, Donnie is sending me some from his original batch to see if that makes a difference. If not, I’ll take a dang road trip to Louisiana and get schooled by Donnie himself.

[Ausglock]

I have asked HITEK Joe for a sample of the last TruBlu batch that went to the US so I can do a test on it with Known equipment, settings and Methodology.
Tazza...1000 yard stare...lol

I have had four people look at the tru blu bullets. Each one gives a different color. Blue, bluish green,emerald. A lot depends on what light they are in. Everybody needs to remember something. Joe busts his hump trying to make what colors his customers want. According to Ausglock the guy don't ever sleep. As I understand the blue is very hard to get. We all have different reasons why we want a certain color. Don't always happen.
