Water-Based Stove Glass Screen Printing Ink

Water-based high-temperature glass ink for cooktops is an eco-friendly, high-temperature firing ink specifically developed for the glass panels of kitchen appliances such as gas stoves, built-in cooktops, induction hobs, and ceramic cooktops. Utilizing a water-based inorganic polymer system with pure water as the diluent, it is free from organic solvents and heavy metals, making it suitable for high-temperature tempered glass manufacturing processes. Upon firing at temperatures between 620°C and 780°C, the ink fuses with the glass to form a dense, eutectic enamel layer, offering excellent properties such as high-temperature resistance, thermal shock resistance, oil resistance, scratch resistance, and ease of cleaning. It meets the rigorous demands placed on cooktop panels in extreme operating environments—including prolonged exposure to high heat, open-flame radiation, frequent cleaning, and acid-alkali corrosion—making it an ideal, environmentally friendly printing material for glass panels used in modern kitchen and bathroom appliances.

Key Product Advantages:

1. Purely water-based, eco-friendly, safe, and low-odor. Uses water as the diluent; the printing process is odorless and free from harmful volatile substances. It causes no environmental pollution and meets requirements for green manufacturing in home appliances and healthy home use.

2. Superior high-temperature and thermal shock resistance. Withstands prolonged high-heat exposure, open-flame radiation, and rapid temperature fluctuations without cracking, blistering, yellowing, or peeling, ensuring stable and reliable performance.

3. Oil-resistant and easy to clean. The fired surface is dense and smooth, preventing oil penetration. Substances like soy sauce, soup, and detergents do not easily penetrate the surface and can be wiped clean effortlessly. It remains free from blackening or stickiness even after long-term use. 4. High hardness, scratch resistance, and wear resistance: Achieves a Mohs hardness of 6 or higher; withstands daily wear, scratches, and impacts, maintaining a pristine, like-new surface finish.

5. Exceptional adhesion, permanent bonding: Forms a chemical bond with the glass substrate at high temperatures, ensuring superior adhesion and resistance to long-term high-temperature aging, humidity, and detergent corrosion.

6. Color stability and high opacity: Black, white, gray, and red colors remain consistent after firing, with no color deviation, fading, or blurring. Printed patterns are crisp with sharp edges, offering a premium, uniform appearance.

Product Applications

1. Household cooktop glass panels: Gas stove panels, built-in cooktop glass, countertop cooktop glass, and high-power cooktop panels (printing for logos, button areas, decorative strips, and borders).

2. Integrated cooktop glass panels: Integrated cooktop control panels, range hood glass, operation/display panels, and decorative glass.

3. Induction/ceramic cooktop panels: Induction cooktop panels, ceramic cooktop panels, and multi-function electric cooktop panels.

4. High-end kitchen and bathroom appliance glass: Dishwasher panels, disinfection cabinet panels, steam oven/combination oven panels, and smart kitchen control glass.

5. Commercial kitchen equipment glass: Heat-resistant windows and panels for commercial stoves, food warmers, noodle cookers, deep fryers, etc.
