I bought some Plasti Dip to use on my wheels and my daughter formed a very good question. How does rubber become a liquid, shoved in a can, stay in there as a liquid, and then dry as a peelable rubber material once applied to a surface? Not just Plasti Dip, but bed liner sprays and other similar products.
I haven’t found a straightforward answer through Google.
In: Chemistry
Just like spray-on glues and paints, the rubber is dissolved in a solvent. Inside the can, there’s nowhere for the solvent to go, so the rubber and the solvent stay in solution. But once you spray the contents of the can out into the world, the solvent can evaporate, leaving just the rubber behind.
