What is a porcelain enamel coating?

Porcelain enamel (also called vitreous enamel or glass-lining) is an engineered boro-silicate glass layer, which may be applied in a liquid or powder form and fused on a metal substrates, like mild steel, cast iron, stainless steel, aluminum or copper.

Unique properties

This inorganic porcelain enamel coating was already used by the Egyptians for art and jewels around 1000 B.C. and may be characterized by a number of unique chemical and mechanical properties, like :

  • Color stability (during many years)
  • Corrosion resistance (even against boiling water !)
  • Easy-to-clean
  • High temperature resistance
  • Scratch resistance
  • Typical applications
  • Enamel on mild steel (Also called ceramic steel or glass on steel) has been adopted by many different industries all over the world.It is nowadays used for providing a functional and/or decorative porcelain enamel coating to a wide range of products.This article comes from dtc-bv edit released

The Purpose of the Black Frit and Spots on Windshield

At some point while driving or examining your vehicle, you may have noticed a somewhat curious pattern along the edge of the windshield consisting of black dots, and commented to yourself, “I wonder what those are for.” The answer to this mystery is rather simple.

The modern windshield is a marvel of engineering, and dare we say one of the most underappreciated components of a vehicle. Part of that engineering involved how the windshield is bonded to the frame. You may have also noticed the black band along the periphery of the windshield, this is called the black frit.

The black frit is a black enamel band that is literally baked into the edges of the windshield glass, accompanied by the border of black dots you are wondering about. The purpose of the black frit is to provide an etched surface that allows adhesive to bond to the glass. When a manufacturer installs a new windshield, or an auto glass specialist like DeDona Auto Glass replaces your windshield, the glass is bonded to the vehicle with the black frit as the contact point between the glass and the frame.

There is a dual purpose here, though. While the inward facing side of the black frit allows adhesive to bond to the glass, the outward facing side of the black frit acts as a shield against UV radiation in order to protect the adhesive bond, which would otherwise be weakened by continual exposure to direct sunlight.

Cosmetically, the black frit also nicely conceals the adhesive used to install the windshield and provides a more “polished” appearance. The dissolving/shrinking effect of the black dots provides a more visually appealing transition from the black border of the black frit to the transparent glass, and also provides a small amount of heat dissipation. The dots do provide some level of sun shade as well.
