Instagoo is a DIY bed adhesive
This amounts to a 70:30 ratio of PVP to PVA in solution, or 21g of PVP-K30 and 9g of PVA for 400ml of 50% Isopropyl. The actual dilution is up to you, this recipe is for a concentrated solution.
PVA is highly soluble in water, so I mixed 9g of PVA in 200ml distilled water. I heated this on my print bed to 70c, and over about an hour it fully dissolved easily.
PVP-K30 is readibly soluble in alcohol or water, but I already dissolved the PVA in water, so I mixed 21g of PVP in 200ml of 99% Isopropyl alcohol. Gentle swirling and stirring and the PVP basically dissolved on it's own.
Combine the solutions, stir well, and portion into small bottles for use. I used some cheap needle-tip precision applicator PET bottleshttps://goo.by.frank.af/ for my mix, although the labels that came with that set don't stick to the bottles at all. A little packing tape fixed that.
If you wanna confuse the chemists, add a little bit of dye to give it a nice color, and don't tell them. Laugh as they start wildly postulating on what could be contaminating your solution
Just ignore everything above. Combine everything, mix with 50% isopropyl alcohol, and shake until its dissolved.
