React-Shun Curing Gel - 1 Liter Bottle

To properly post-cure all stereo lithography resin parts you must do it "oxygen free". This is especially important for all materials that will come into contact with the body for extended periods (bio-compatible), or directly castable "resins". You can purchase our 200 Watt Broad Spectrum UV High Intensity Xeon Flash with the inert gas option or you can use this gel mixed well 50/50 with DI water and cure in the 36 watt curing unit that comes with the Asiga Systems. I suggest the High Intensity Unit for medical applications or applications where you have a need for production speed.

The other option is to use our React-Shun Curing Gel instead. Put your parts into a small optically clear Pyrex glass dish and pour the 50/50 blend of curing gel and DI water in on top of them. The purpose of mixing 50% with DI water is to lower the specific gravity of the liquid. Our curing gel has the same specific gravity as most printing resins so your parts will likely float and be exposed to air if you use Curing Gel only. You can also use a small clear zip lock bag (ring bag). Squeeze the air bubbles out of the gel in the plastic bag and zip it and put that into your open air cure unit.

The goal is to get the parts completely covered under the gel/water mix and away from any oxygen. If you are using the bag method, rinse off the bag with tap water, if you want to, in order to get any gel that may have squeezed out of the bag. Put the bag into the curing box and cure on one side for about 15 minutes, then flip the bag over and cure on the other side for the same. 15-30 minutes in the curing box should be sufficient for most parts. Very thick parts may require more time.

React-Shun Curing Gel is a very safe, non-toxic, reusable material. Simply remove the parts from the gel, drip off as much as you can back into your container, and rinse off your parts with tap water in the sink. After rinsing and drying your parts, apply your feed sprues to your parts before you dip them into our other product, "React-Shun RP barrier dip" in preparation for direct casting or molding. Only one dip is sufficient for molding in low temperature vulcanized rubber. 3 - 5 dips using a light compressed air blow off prevents material from creating filets in deep recesses. React-Shun RP barrier really improves direct casting using regular gypsum bonded investment. 4 dips is a good average.
