Hey all, not to be a spoil sport, I know everyone is search of the answer to the reaction layer issue, however I think you should be careful.
I got some info off of their website:
Box comprising 35 x 100g foil sachets of JPVest, 500ml of JPLiquid (complete with freeze indicator), 1 set of instructions and 1 syringe.
You guys are willing to pay that???? Plus shipping to the USA????
That's more approximately 3 times the price of Zubler 144 and almost twice what Ivoclar's investment is.
100 packages month (1 case of Zubler 144 (100x100g @ $114.00) vs 3 x cases of JPVest):
approximate extra $ you are spending:
$300 x 12months = $3600
$300 x 24months = $7200 (Almost paid for an VARIO PRESS 300.e)
Just a thought...
We are the distributor for JP Vest in the USA through our supply company, Toothworks Dental Supply
The price Chris quoted is from the UK site.
The current price from us is USD$345 for 100 x 100g packs and 2L of liquid which is actually less than Ivoclar's PressVest.
In our lab we noticed quite a difference in our emax pressings not only was our reaction layer eliminated but the surface of the pressed units was much smoother. So smooth that on some crowns you can get a nice surface finish just by polishing it with diamond polishing paste and completely skip the glaze firing if you are not going to add characterization staining. It is a big time saver for us.
JP Vest's patented formula is truly unique, it is much more than just some "magic powder" that gets mixed in to the investment.
If you would like to see for yourself how JP Vest can benefit you and your lab just let me know and we will send you a sample.
UPDATE: I placed an order for their sample pack on March 6, 2015 and have not received it as of today March 18. Still waiting. For now Galaxy II from Talladium has been working out great for us, and is very price friendly.
I just sent you a PM, we will take care of you
I also have a sample pack on the way...Could you please pass along a good starting point for mixing ratios? Or what you are currently having success with ? Thanks you.
16mL special liquid + 8mL distilled water per 100g of investment. This is the ratio we have found that gives us the best fit.
We are using an Ivoclar EP5000 for our pressing if anyone was curious.
Doug i use the old EP 500, and i use Talladium investment, Gallaxy 2 i think. I don't get the layer on emax anymore, but i lowered the temp on the pressing unit all the way to the lowest levels. When i first started i used the temps by the book, with the same investment and furnace, and i used to get the layer. I got that acid Ivoclar is recommended but didn't do much. I think the temperature in the book is too high. that's why we get that layer. But not anymore for me. Adrian
We are getting phenomenal results with our metal castings with JP Vest too. As you can see in this photo JP Vest delivers a precision fit and incredibly clean, smooth metal castings.
We recommend the following special liquid ratio for metal castings; 20mL of JP Vest Special Liquid + 4mL distilled H2O per 100g of JP Vest. A conventional burnout must be used with this,
These were done with Ivoclar d.sign 91 60% ceramic gold alloy using a conventional burnout; 50°F per min to 400°F, hold for 30 minutes, 30°F per minute to 1450°F, hold for 60 minutes.
We. Just had a conversation on fb about this .a lab in Texas sells the jp investment
I said it on a different thread.
This investment material is fantastic. Period.
