Hello!
Here I come with sodium silicate questions again.
I have only found one product on the market. Nitor's water glass, 1 liter, "Vattenglas Natron artnr. 203067". It has 57% water and 29% silicate content. What could the other 14% consist of? I am doubtful about this product. From what I understand, water glass is supposed to have a syrup-like form.
Today I received a response from Nitor:
Quote: The product consists of water and sodium metasilicate. Consistency/viscosity is not stated in the safety data sheet. It is a viscous liquid, heavier than water but not as "elastic" as syrup.
No expiration date. It is an inorganic product, so nothing happens as long as the package is sealed. Drying time is at least 12 hours.
Is this a good water glass? As I mentioned, I thought it was supposed to be much thicker, but on the other hand, I have never played with sodium silicate.
---
I was otherwise looking for a water glass as viscous as possible, preferably powdered. Does that even exist? Where?
How much does it cost? I assume the shelf life is eternal on that too?
How long is FULL curing time in total? Until it's as hard as stone, that is.
---
Here, by the way, is a bunch of statements about Water Glass. Which are true, which are not?
STONE HARD, durable surface
Non-toxic
Not glossy
Non-yellowing (time-resistant)
UV-resistant
Water glass does not damage paper and printer ink
You can "preserve" paper with water glass
Thanks!

Noted that for use, it should be diluted 1:1 with water.
Unlike silicate primer, waterglass (i.e., one part of the "real" silicate painting technique) contains no acrylate dispersion.
The content of acrylate dispersion in silicate primer seems to be a bit (2.5-10%) in the silicate primer. But if you want to be completely on the non-toxic side and ensure that moisture can move freely, you cannot use silicate primer.
