Chemically Strengthened Glass
lonGard process is the new and sophisticated way of strengthening glass. Thanks to this technology, the geometry and thickness of a glass required by its design becomes irrelevant for the matter . lonGard Glass can be used as a durable structural element in any shape and form. The unique combination of strength and beauty of lonGard chemically strengthened glass paves the way for creating exciting new design possibilities in modern architectural projects. Some of the features of IonGard are as follows:
• Up to 10 times stronger than an annealed glass,
• Glass thickness ranging from 0,2 mm to 25 mm,
• Largest plant in the world in terms of volume with glass panel up to 7200 W x 3300 H x 2000 D mm.
• Any complex 2D or 3D geometry is possible,
• Perfect final optical quality.
The rules of glass have changed.
The process of chemical strengthening consists of submersing the glass for a given period of time in a special chemical bath at 480°C. During the submersion cycle, the chemical ions are exchanged with the sodium ions. The larger ions "wedge" their way into the voids in the surface of the glass created when the smaller sodium ions migrate to the special solution. This ion exchange lacks the surface of the glass in a state of compression and the core in compensating tension. The resulting glass is strengthened.
Properties oflonGard@ Chemically Toughened Glass
• lonGard is five to ten times stronger than comparable annealed glass
• lonGard retains its colour and light transmission properties after treatment
• Unlike thermally toughened glass, there is no risk of spontaneous glass breakage for lonGard
• Due to its manufacturing process, lonGard has no bow or warp, optical distortion or strain pattern
• lonGard breaks into sharp fragments like annealed glass.
• The sufface compression of lonGard may reach up to 690 MPa for a thickness of approx. (50pm)
