The paint used to coat metal roofing and siding panels has three basic components: pigment, which creates the color; solvent, which helps to dissolve the pigment; and binder or resin, which acts like the glue to hold everything together.
Due to differences in both pigment cost and the amount of pigment required, most metal panel manufacturers segment their PVDF (Polyvinylidene Fluoride) offerings into three pricing tiers.
