Does ZnO affect epoxy?
The degradation of epoxy coatings having various filler materials has been studied under natural and accelerated environmental conditions. ZnO-containing epoxy coatings show more pronounced UV stabilization characteristics, which could extend the service life of the epoxy coating compared to other filler materials exposed to same environmental conditions. The relatively minor decrease in the adhesion strength by ZnO-containing coatings indicated its better mechanical integrity and UV resistant characteristics compared to coatings containing TiO 2, Fe 2 O 3 and graphite filler materials. The addition of antioxidants and photo-stabilizers in the epoxy coatings shows excellent resistance during aggressive salt spray tests with a negligibly minor loss in the adhesion strength without any blistering.

Simply reduce it 50 percent and lay a coat or two down to seal up all of your work and have a nice surface to lay your base coat over top of. The primer has excellent adhesion to most topcoats and will help keep actual paint from flaking or peeling. This is great peace of mind for a lasting paint job.
What is an Epoxy Primer?
To put it simply, it’s a type of sealer or filler that can be applied to a wide range of surfaces for protection or to fill in imperfections. For instance, it’s typically used on cars and boats to fill in dents, cracks, and rust and to offer a long-lasting, non-porous smooth finish with anti-corrosion properties. This finished surface is solid and very hard, so it can be sanded with a sander for an ultra-smooth finish that is easy to paint. Speaking of paint, with a quality epoxy primer, you can paint your vehicle more uniformly (as all dents and cracks are smoothed out), resulting in a better-looking and more professional paint job. Also, a good-quality epoxy primer provides durable protection that doesn’t degrade over time (at least nowhere near as fast as the surfaces would degrade without a primer).
