Specialty Coatings - Environmental Specific
Harsh environments may require a specialty coating that offers enhanced performance over the standard PVDF (Kynar 500) systems. Coastal and chemically dense environments such as manufacturing with chemical discharge are two examples. McElroy Metal offers several Sherwin Williams specialty coatings to meet these types of severe environmental conditions.
Flurothane® PVDF coil coating systems include thick-film primers to give the metal substrate superb protection against the harshest industrial environments. In addition to ensuring a strong adhesion to the substrate, these thick primers also allow for superior adhesion of the topcoat, which provides even more protection of the base metal.
Valshield is a PVC-technology coating designed as a durable coating ideal for applications that require great resistance in corrosive environments. Made of vinyl plastisol polyvinylchloride (PVC), Valshield offers great resistance to corrosion, abuse, and abrasion. Because of this, it works particularly well for buildings that are exposed to acid rain. While the coating is much more durable, Valshield is not a PVDF coating. Consequently, panels are more susceptible to fade and chalk than Flurothane coatings.
