What is Important in Fastener Finish Systems

Plating Definitions

Electroplating is a method of depositing zinc on the surface of the part using an electrolytic attraction of the zinc to the fastener. Electroplating deposits a dense coating of zinc over the entire surface of the part. The zinc plating is a sacrificial coating protecting the base part from scratches or other coating breaks.

Mechanical plating is a method of depositing zinc on the surface of the part using a hammering or impact process. This method applies the zinc to the entire surface of the part. Mechanical plating deposits a less dense, but thicker coating of zinc over the surface of the part. The zinc plating is a sacrificial coating protecting the base part from scratches or other coating breaks.

VistaCoat Premium System Coating

SFS intec developed the VistaCoat Premium System finish for panel attachment fasteners. Utilizing new coating and processing technology, the finish has improved appearance, corrosion resistance, durability, and installation perofrmance, and it covers the entire fastener.

The finish system consists of
- zinc plating
- pre-treatment
- seal coat
- primer coat
-color top coat in multiple layers

VistaCoat Premium System is standard on the following exterior panel attachment fasteners in any of the SFS intec standard colors and plain silver.

What is Important in Fastener Finish Systems?

Adhesion of the coating to the fastener
Each material substrate from the steel fastener surface to the topcoat relies on the integrity of the bonding interaction of the layers to provide the adhesion and abrasion resistance of the overall coating system.

SFS Chromagardâ„¢ Acrylic Polyurethane Color Coating

SFS has been involved in the application of fastener coatings in North America for nearly half of a century. In recent years we have partnered with worldwide coating and finish system manufacturers in the development and application of systems to meet our customers' needs.

Chromagard is the metal building industry's preferred fastener topcoat due to its strength, adhesion, and color-fast characteristics.

Chromagard is a high-performance color-coating system based on polyurethane coating systems technology. The two-component acrylic polyurethane coating is spray applied to Silver Sentri coated fastener head and washer.
Color match is guaranteed for every color and every fastener.
Chromagard is available on all Impax, Woodgrip, and other Weather Gard fasteners.
Chromagard technology is based on construction and automotive finish systems.
Chromagard has superior resistance to installation abrasion for in-place appearance and performance.

Color shift resistance of the top coat
"Color shift" is the changing of color, over time, as compared to the original new color appearance. Color shift, combined with reduced gloss, brings about the "faded" appearance we see on old painted surfaces. SFS intec has conducted accelerated exposure testing to confirm the performance of Chromagard.

Chromagard provides resistance to sunlight exposure for superior product appearance for the life of the building.

Corrosion resistance of the fastener
Chromagard is the topcoat of an integrated plating and corrosion resistant coating system. The interrelationship of the layers of plating, Silver Sentri, and the Chromagard topcoat provides the complete corrosion resistance performance of the finish.
