Creates a softer, finer glaze surface, eliminates pores, widens firing range, and enhances color vibrancy. High-alumina formula delivers exceptional hardness to resist daily scratches; polishing restores a new-like shine. Ideal for premium glossy tiles. Glaze exhibits a silk-like texture with adjustable gloss (soft-gloss to micro-gloss), avoiding harsh glare of standard gloss tiles while preventing dullness of matte glazes. Tactile feel resembles natural stone—warm and non-cold, enhancing spatial affinity. High-zinc content adds micro-elasticity to absorb minor impacts and reduce visible scratches. Strong self-leveling properties during firing fill micro-unevenness in the body, drastically reducing pinholes and melt holes. For luxury minimalist tiles.

Floor Tile Polished Glaze Frit is engineered for high-wear commercial and public environments, integrating 20% Al₂O₃ (for extreme hardness) and 3% zirconium oxide (for flexibility). The frit creates a smooth, semi-gloss finish with glossiness of 90 GU (60° angle) while maintaining enough flexibility (elongation at break: 1.2%) to prevent cracking under tile thermal expansion (10-12×10⁻⁶/℃). It melts at 1250-1280℃, with a firing cycle of 90 minutes (standard for commercial tile lines), and meets EU CE EN 14411 standards for floor tiles. The frit powder is non-toxic, with no heavy metals (lead, cadmium) and low VOC emissions.
Extreme Durability: Withstands 10,000+ revolutions in the Taber abrasion test (CS-17 wheel, 1kg load) with <0.02g weight loss—suitable for high-traffic areas like airports and train stations (50,000+ steps/day).
Thermal Stability: Resists cracking from sudden temperature changes (0℃ to 80℃), making it ideal for indoor spaces with underfloor heating or outdoor covered areas (e.g., mall atriums with glass roofs).
Eco-Friendly: 100% recyclable frit powder—unused or expired powder can be reprocessed into new frit, reducing industrial waste by 30%. It also has a low carbon footprint (500kg CO₂/ton produced, 20% lower than industry average).
Color Compatibility: Maintains the integrity of colored underglazes (digital or screen-printed) without fading or bleeding—works with all standard ceramic pigments (e.g., chrome green, manganese brown).
Application Scenarios: Airports (terminal floors), train stations (platforms), schools (classrooms and hallways), commercial kitchens (restaurant floors), and shopping mall food courts.
Operation Guidelines: Mix the frit powder with deionized water and 0.8% CMC to form a slurry (viscosity: 1800-2200 cP). Spray-glaze at 0.4MPa pressure, ensuring uniform coverage (target thickness: 0.35mm). Fire at 1280℃ with a 30-minute peak hold—this temperature optimizes Al₂O₃ crystallization for maximum hardness. Cool the tiles at 80℃/hour to avoid thermal shock.
Q: Can it be applied over colored underglazes?
A: Yes—its low alkali content (<4%) prevents interaction with underglaze pigments, maintaining color integrity without fading or bleeding. Test with the specific underglaze first (we provide free test samples of common pigment combinations).
Q: What causes blistering in the glaze?
A: Blisters are usually caused by contaminants (oil, dust, organic residues) on the tile surface—clean tiles with 10% ethanol (wiped with a lint-free cloth) before glazing. Other causes include excessive moisture in the slurry (ensure water content is 45-50% by weight).
Q: Is it compatible with digital printing inks?
A: Yes, it is tested and approved for use with both UV-curable and water-based ceramic digital inks (e.g., EFI, Durst inks). The glaze’s smooth surface ensures the ink adheres evenly and retains color after firing.
Q: What’s the minimum order quantity (MOQ)?
A: The MOQ is 500kg per color (only white available for this frit). For orders of 1000kg+, we offer a 5% bulk discount and free shipping (to major ports worldwide).
Q: How to handle transportation in cold weather?
A: During winter (temperatures <5℃), transport the frit in temperature-controlled trucks to prevent freezing—freezing may cause the powder to clump, altering its melting properties. If clumping occurs, sieve through a 150-mesh screen before use (do not grind).
