The use of tempered coatings has grown significantly in recent years across multiple industries due to the unique properties they provide. Tempered coatings undergo a careful heating and cooling process that increases their durability, hardness and resistance to breakage when stressed. In this article, we will explore the advantages of tempering coatings and how various industries are utilizing these coatings to improve safety and performance.

Tempered coatings undergo a heat treatment process called tempering where the coating material such as glass or metal is carefully heated to specific temperatures just below the annealing point and then cooled in a controlled manner. This process relieves internal stresses in the material and increases its mechanical strength. The exact tempering temperature and cooling rate depends on the material being coated but it leads to properties like higher resistance to breakage from impact or flexing forces.

Manufacturing and industrial equipment see extensive use of Tempered Coatings for components that undergo rigorous operational stresses. Items like drill bits, cutting tools, blades and wear parts have tempered steel or carbide coatings for their ability to retain sharpness and withstand friction or pressure. Other industrial applications include tempered glass for equipment display/control panels, warehouse skylights and commercial greenhouse glazing.

On the consumer front, nearly all tabletop glass and ceramic cookware today uses a tempering process to make them impact resistant and less prone to shattering. Safety glass for framed pictures, mirrors and home furniture also rely on tempering. Even transparent armor in bulletproof vests and ballistic shields utilizes tempered multilayer designs to absorb impact. Tempering has also found uses in renewable energy, with robust tempered coatings used for wind turbine blades and solar panel front sheets.
