Product Details

Our nitrate additive greatly enhances the burnout of your resins.

This is 1000grams of pure Ca(NO3)2 in a 70% solution. That means that the bottle has a little over 1428 grams of liquid in it. Selling it this way makes it safe to ship and handle in your shop. What this means is that you would add 28.6 grams of this liquid into your liter bottle and then you would fill up that bottle with DI water to create a 20% solution of Calcium Nitrate.

In a perfect world you had already heated up about half of your required water for casting and dissolved 20 grams of granular H3BO3 (Boric acid), into it already. If so then this is how it would work. Add the 28.6 grams of our Calcium nitrate solution from the bottle into your container. Pour the water containing the dissolved boric acid in on top of that. Add the other water until you get to 1 liter. You now have a 2% solution of H3BO3 and Ca(NO3)2 per liter of water. Use this water to invest your RP parts with your normal gypsum bonded investment. Using high quality (high cristobalite) investments is best.
