Why doesn epoxy peel under hot car tires?
Epoxies exhibit much greater adhesive strength than other types of coatings. Traditional store bought floor paints are mostly oil base type (alkyds) or latex/acrylic. Automobile tires generate a fair amount of heat when spinning on pavement. When the tires roll onto a painted surface, the heat softens these general purpose paints. The combination of the heat and pressure caused by the weight of a vehicle causes the paint to stick to the rubber and lift from the substrate. The chemically cured film of a 2 component epoxy is not subject to this softening caused by heat and therefore will not lift or peel like a conventional paint.
