Introduction:Glass Melamine Laminate is a high-performance composite material that has emerged in recent years. Its essence is the product of combining melamine resin (Melamine Resin) with glass substrate through a special lamination process.
Product Description
This Glass Melamine Laminate is made of alkali-free glass cloth impregnated with melamine formaldehyde resin by drying and hot pressing. It has good arc resistance and certain dielectric properties and flame retardant properties. Glass Melamine Laminate features glass cloth layers that are soaked with melamine resin and then treated in high temperature and pressure. Consequently, what comes from here is a firm laminated sheet which can resist heat; it is also a good insulator for electricity. Glass Melamine Laminate has high mechanical strength, non-flammability, and resistance to chemicals and moisture. Glass Melamine Laminate are used extensively in electric appliances like switchgear, transformers, and motors where dependable insulation is required for safety and performance reasons.

Technical process
Substrate pretreatment: Use high-purity float glass or tempered glass as the substrate, and after precision cutting and edge polishing, ensure that the surface flatness reaches the nanometer level standard.
Melamine resin coating: Use precision coating equipment to evenly coat the liquid melamine resin on the glass surface, and control the coating thickness (usually 0.3-0.8mm) to achieve performance regulation.
High-temperature hot pressing: Vacuum hot pressing is performed at 150-180℃ to make the resin layer and the glass substrate combine at the molecular level to form a dense seamless interface.
Surface functionalization: Anti-fingerprint coating (AF Coating) or antibacterial nano-coating treatment is performed according to application requirements to improve surface performance.
The key to this process is the control of the interface bonding strength between the resin and the glass. The thermal expansion coefficient matching technology is required to ensure that the material maintains structural stability in the temperature range of -40℃ to 150℃.
