I need a liquid release agent for my application, I have plenty of wax for normal use.

My Acraglas release agent ( the blue stuff) has congealed into a jelly, anyone know what I can use to thin it out again, Brownells didn't know.


thanks, Rob

I am sure the directions say or used to say rubbing alcohol is the thinner. That is what I use when it gets a little too thick. It may or may not work on jelly thick stuff though.

Johnson's floor wax works fine. I wouldn't even bother with trying to thin the release agent product.

Hornady One Shot case lube works great also.

As does just about any rattle-can silicone spray...

I seem to recall alcohol also. I think it says it on the bottle? Maybe it was the paper directions. I also prefer floor wax.

I have heard of lots of field expedient release agents, including PAM cooking spray, but am too chicken to try any! I have a hard enough time getting the darn things apart when using the specified release agent.

I would like a better release agent because peeling that blue saran wrap out of the nooks and crannies in the stock gets very old, very quick!

I also believe alcohol would work. It seems to me that there is alcohol in it to begin with.

On a related note, the Acraglass release agent seems to have changed in the last few years. It seems thin and watery now compared to the old stuff. Seems to take several coats to get a good solid coverage.

I tried denatured alcohol and it didn't dissolve the clumps, just loosened them up. Ended up using KIWI wax.

The new Acraglas release agent is listed as NON-FLAMMABLE, maybe that's why it's not as good as it used to be.

Minwax paste floor wax has worked great for me. Wrap it up in some cheese cloth and it makes it really easy to apply.

More than likely Methyl isobutyl ketone . You could try acetone but why bother ?.

Use a quality paste wax apply three coats wiping or buffing off each coat after drying .

It insures even the smallest nook or cranny will release , I detest silicone especially around

wood or other porous substrates .

Brownell's sells a spray can release agent. It's quick, covers everything and works great. All I use now, best I've found.

The Acraglas agent is PVA which stands for polyvinyl alcohol. I don't know what type alcohol is in it though. It is water soluble after it dries.

PVA can also be Polyvinyl Acetate and is commonly used ;



As an emulsion in water, PVAc emulsions are the adhesives for porous materials, particularly for wood, paper, and cloth, and as a consolidant for porous building stone, in particular sandstone.[2] Uses:

* as wood glue PVAc is known as "white glue" and the yellow "carpenter's glue" or PVA glue.
* in paper converting as fast binding adhesive
* in bookbinding and book arts due to its flexible strong bond and non-acidic nature (unlike many other polymers).
* for handcrafted works.

To a lesser extent PVA emulsion are used in paper coatings, paint and other industrial coatings. PVA can also be used as coating to protect cheese from fungi and humidity.


Polyvinyl Alcohol is commonly used in the FRP industry as a release agent .


Some other uses of polyvinyl alcohol include:

1. Adhesive and thickener material in latex paints, paper coatings, release liner, hairsprays, shampoos and glues.
2. Textile sizing agent
3. Carbon dioxide barrier in polyethylene terephthalate (PET) bottles.
4. Carotid phantoms for use as synthetic vessels in doppler flow testing.
5. Movie practical effect and children's play putty or slime when combined with borax.
6. Feminine hygiene and adult incontinence products as a biodegradable plastic backing sheet.
7. As a mold release because materials such as epoxy do not stick to it.
8. As a water-soluble film useful for packaging.
9. As fiber reinforcement in concrete
10. As a surfactant for the formation of polymer encapsulated nanobeads
11. Used with polyvinyl acetate to make Elmer's glue
12. Used in eye drops and hard contact lens solution as a lubricant.
13. Used in protective chemical-resistant gloves
14. Used as a fixative for specimen collection, especially stool samples
15. When doped with iodine, PVA can be used to polarize light.
16. As an embolization agent in medical procedures

Same for me. It's called Acra-Release Aerosol. Great for a skin tight fit and cleans easily. Paul.
