High-temperature ink for quartz furniture glass is an inorganic high-temperature sintering screen printing ink specially customized for tempered quartz glass, high borosilicate glass, and decorative furniture glass. Its core components are low-melting-point glass powder (fuse), high-temperature resistant inorganic pigments, and environmentally friendly inorganic binders, and it contains no heavy metals or harmful volatile substances. After tempering/sintering at 680–850℃, the ink layer undergoes eutectic bonding with the glass substrate, forming a dense, hard, and permanently adhered inorganic enamel layer. This layer combines high hardness, scratch resistance, weather resistance, corrosion resistance, and environmental safety, perfectly meeting the printing needs of decorative, labeling, edge sealing, and functional panels on furniture glass. It solves the problems of ordinary inks such as easy peeling, discoloration, poor high-temperature resistance, and difficulty in cleaning.

Core Product Advantages
1. High-Temperature Co-melting, Permanent Adhesion: The ink and glass fuse at high temperatures, forming a chemical bond structure that prevents peeling, flaking, and ink loss. Suitable for post-processing such as glass tempering, hot bending, and cutting, it remains firmly bonded even after long-term use.
2. High Hardness and Wear Resistance, Scratch-Resistant and Durable: After sintering, the Mohs hardness reaches 6-7, making it resistant to scratches from daily wiping, friction, and contact with hard objects, far exceeding ordinary low-temperature inks and extending the lifespan of furniture glass.
3. Weather and Corrosion Resistant, Long-Lastingly New: Resistant to acids and alkalis, detergents, boiling water, and ultraviolet rays. It does not fade, chalk, or discolor under long-term exposure to sunlight, humidity, or kitchen and bathroom environments, maintaining a consistent appearance. 4. Excellent printability and stable color: Good leveling properties, strong opacity, and clear edges; supports large-area printing and intricate patterns; gloss and matte finishes and colors can be customized; no color difference or yellowing during sintering.
5. Environmentally friendly and safe, home-friendly: Inorganic formula, free of heavy metals and odors; meets environmental protection requirements for home and child contact applications; suitable for indoor furniture and kitchen/bathroom settings.
Product Application Areas
1. Living Room Furniture Glass: Glass coffee table tops, TV cabinet panels, display cabinet glass, partition glass, decorative glass door panels, frames, logos, color blocks, and texture printing.
2. Kitchen and Bathroom Furniture Glass: Bathroom cabinet glass, kitchen cabinet doors, bathroom mirror edge sealing, countertop decorative glass; water-resistant, detergent-resistant, and high-temperature steam resistant.
3. Office/Commercial Furniture Glass: Office desk tops, conference table panels, filing cabinet glass, shop display glass; wear-resistant and scratch-resistant, suitable for high-frequency use scenarios. 4. Custom-made Artistic Furniture Glass: Quartz glass furniture in light luxury, minimalist, and neo-Chinese styles, supporting high-end decorative effects such as imitation stone texture, matte, mirrored, and gradient finishes to enhance product added value.
5. Matching Functional Glass: Furniture touch panels, lighting glass, and protective glass panels, balancing aesthetics and structural safety to meet the needs of multifunctional furniture.
