Highly Resistant glass is made using a chemical reinforcement process which greatly improves the mechanical resistance.

Weight watcher: Highly Resistant glass allows to decrease glass thickness and reduce weight whilst maintaining strength.

Perfect optical quality, no shading or strain pattern.

Available on any glass thickness. For Transport & Industrial Vehicles applications, AGC usually uses glass from 0.7mm to 25mm.

Technical information

Highly Resistant glass is made using a chemical reinforcement process. Glass is immersed in a high temperature bath to replace sodium ions (Na) with potassium ions(K) putting the glass surface in compression, making the glass substantially more resistant to mechanical shocks and to thermal stresses.

Highly Resistant glass keeps its initial flatness and optical quality with no strain pattern, as if it was annealed glass (unlike thermally tempered glass).

Highly Resistant glass maintains residual visibility after breakage unlike thermally tempered glass which brakes in very small pieces which prevents acceptable visibility. Therefore, Very High Resistant glass will be laminated to consider it as a safety glass.

At equivalent performances, Highly Resistant glass allows the use of thinner glass giving the benefits of reductions in both weight and thickness.

Typically used for windshields, lightweight side windows or interior glass.
