Hydrogel N not setting up

Postby Tammie.l.hyde » Mon Jan 11, 2016 3:15 pm

Ok, so I followed the 4:1 ratio for the hydrogel N as listed on the box casting video. I ended up with clumpy hydrogel that did not set up properly - still feels wet and mushy hours later. Any clue as to what I did wrong?

Thanks!

Hi Tammie,

I'm sorry that the Hydrogel-N did not work as expected.I am told that there are a couple of possibilities:

1) It needs to be mixed more aggressively and for a longer time. It really needs to be agitated.
2) It was too old. The technical sheet on the material says that it has a shelf life of “at least 6 months in an unopened container…”

Do either of these possibilities seem to explain what you observed?

Hello Tammie,

Just dropping a note to let you know that we have changed the alginate product we work with and sell.

'Hydrogel-N' has been discontinued by the manufacturer. In its place we are now using 'Accu-Cast Alginate 880 Blue'.

Here is the information we have regards working with it including a PDF.
http://www.bullseyeglass.com/methods-ideas/working-with-accucast-880-blue.html

Here it is in our store, available in both 1.5 lbs (.68 kg) and 12.5 lbs (5.7 kg) containers.

http://shop.bullseyeglass.com/tools-supplies/bullseye-line/accu-cast-alginate-880-blue-12-5-lbs-5-7-kg.html

All of our testing so-far shows 'Accu-Cast Alginate 880 Blue' to be just as good if not a better product than 'Hydrogel-N'. We'd love to hear your experience when you get to give it a try.

Thanks,
Chris
