Water-based High-temperature Screen Printing Ink
Water-based high-temperature screen printing ink is a specially formulated ink designed for screen printing on surfaces exposed to high heat, such as ceramics, glass, metals, and fabrics used in industrial applications. Unlike solvent-based inks, water-based inks are eco-friendly, low in VOC emissions, and safe for workers, while still offering excellent adhesion, high-temperature resistance, and vibrant colors.

Product Introduction
Composition of Water-Based High-Temperature Ink
The main components of water-based high-temperature inks include:
Pigments: Provide color and opacity. High-quality inorganic pigments ensure excellent heat resistance.
Binders/Resins: Heat-resistant polymers that help the ink adhere firmly to surfaces during high-temperature curing.
Water: Serves as the primary carrier, replacing solvents and reducing VOC emissions.
Additives: Improve flow, printability, adhesion, and heat resistance. Examples include surfactants, stabilizers, and thickening agents.
The careful balance of these components ensures that the ink remains stable during printing, cures properly at high temperatures, and produces durable, vibrant prints.
Advantages of Water-Based High-Temperature Screen Printing Ink
Water-based high-temperature screen printing inks offer several benefits compared to traditional solvent-based or low-temperature inks:
✔ Heat Resistance
Cured prints withstand high temperatures without fading, cracking, or losing adhesion, making them ideal for industrial and household applications.
✔ Environmentally Friendly
Low VOC content makes these inks safer for workers and reduces environmental impact.
✔ Excellent Adhesion
Bonds securely to materials such as metals, ceramics, glass, plastics, and textiles.
✔ Vibrant Colors and Consistency
Water-based pigments provide sharp, vivid, and consistent color reproduction.
✔ Easy Clean-Up
Water-soluble formulas allow easy cleaning of screens and equipment without harsh solvents.
✔ Versatile Applications
Suitable for industrial production, decorative printing, promotional items, and heat-processed products.
FAQ:
How It Works – Printing and Curing Process
Water-based high-temperature screen printing ink follows a straightforward printing and curing process:
Screen Printing: Ink is applied onto the substrate using a mesh screen.
Drying: Excess water evaporates, leaving a thin layer of ink on the surface.
High-Temperature Curing: The substrate is exposed to heat, often in an oven or kiln, causing the binder to polymerize and fuse the pigments to the surface.
Final Result: The print becomes durable, heat-resistant, and ready for industrial or consumer use.
The high-temperature curing step ensures that the ink forms a stable and long-lasting print that can withstand heat, washing, and mechanical abrasion.
