Re-tasking Nail Polish as Protective Coating
Cerebus:
--- Quote from: Kleinstein on October 04, 2021, 10:49:54 am ---Moast Nail finish is nitrocellulose based. As such it it not very durable and likely to develope cracks after a few years. It is also highly flammable, not just liquid, but also when dry. I had some rosin based laquer that I used for protecting PCPs, so kind of non activated flux.

I suspect not nowadays. Looking at the bottle I've got here, with the ingredients listed in descending quantity order as is normal for cosmetics, there is some nitrocellulose but the base polymer is Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer. There are another 3 complex copolymers listed.

The nailpolish i use are made in China cost 1 euro for 15ml made of: ButylAcetate , Ethylacetate , Acrylates , Copolymer , Nitrocellulose , Alcoholdenat , Acetyl , Tributyl ,
Citrate , Isopropylalcolhol , Steralkonium , Hectorite. Used for locking, surface patching, coil surface repair etc and have not noticed any cracking after many years of use
for non vibrating surfaces. The mix ratio of these chemicals is not reported on the polish container.
Just did a fire test, painted a 10mm x10m area with the nail polish mentioned above on a piece of paper and set it on fire,
no extra or excess flaming occurred when the fire crossed the painted area. Larger thick surfaces perhaps react differently.
