Large Area Glass Coating

Since the vacuum coating technology for the deposition of optical thin films on large area glass substrates has gone through a steady growth for decades, nowadays, by complicated optoelectronic thin film coated, large area glasswith high performance functions like energy efficiency and outstanding aesthetic optical appearance, play more and more importantrole in our life.

Low emissivity (Low-E) architectural glass is one of them, the coating prevents solar radiation from passing through the front of the glass and radiant heat from escaping the building by reflecting it on the back side of the glass, torealize energy efficiency.

Architectural glass (especially Low-E) materials are highly transparent and neutral in color, tinted solar and low-e solar control combinations.


This diagram shows the general structure of a triple silver low-e coating with approximate thicknesses of each layer, as indicated by various patents.

Automotive Glass materials are highly transparent and electrically conductive for flat or bent glass, solar control, mirrors and defrosting layers.

As a leading manufacturer for thin film coating materials, Haohai Metal (Haohai Titanium) develops and provides sputtering targets cover larger planar and rotatable targets for various large area coating applications such as Low-E glass, Anti-reflective glass and Photovoltaics and Flat panel displays.
