High initial melting point, excellent color vibrancy, broadened firing range, and reduced pinholes. High-alumina formula delivers extreme scratch resistance; polishing achieves renewed gloss. Glaze surface resembles polished obsidian (>95° gloss), clearly reflecting objects under light to enhance spatial transparency. Barium improves flow for self-leveling, eliminating orange peel/ripple defects and achieving zero-pore smoothness. High-alumina skeleton resists high-temperature deformation, compatible with slow firing (60–90 min cycles) without sagging. Resists micro-cracks during cooling.

Floor Tile Polished Glaze Frit delivers a mirror-like high-gloss finish for modern flooring tiles, with a glossiness rating of ≥95 GU (measured at 60° angle per ASTM D523). The frit is formulated with TiO₂ (8-10%, for crystallization control and gloss enhancement) and ZnO (3-5%, for adhesion improvement), creating a dense, scratch-resistant layer on porcelain and ceramic tiles. It has a melting range of 1150-1200℃, with a firing shrinkage rate of <2%, ensuring compatibility with standard tile production lines. The frit powder is white, odorless, and non-toxic, meeting EU REACH regulations (no restricted substances).
Superior Shine: Maintains ≥90 GU glossiness after 2 years of heavy foot traffic (equivalent to 50,000 steps/m²), outperforming standard polished glazes by 30% in gloss retention.
Wear Resistance: Boasts a Mohs hardness of 7—resists scuffs from furniture legs (with felt pads) and foot traffic (including high heels); passes Taber abrasion test (CS-17 wheel, 1kg load) with <0.01g weight loss after 1000 revolutions.
Easy Maintenance: Non-stick, smooth surface reduces cleaning time by 40% compared to matte alternatives—dust and dirt can be removed with a dry mop, and stains (e.g., ketchup, soda) wipe clean with mild detergent.
Chemical Resistance: Withstands contact with common household cleaners (pH 2-12, e.g., vinegar, bleach) and commercial floor cleaners for 24 hours without discoloration or etching.
Application Scenarios: Shopping malls (high foot traffic), office lobbies, hotel corridors, luxury residential living rooms, and airport departure halls.
Operation Guidelines: Mix the frit powder with deionized water and CMC (carboxymethyl cellulose, 0.5% of total weight) to form a slurry (viscosity: 1500-2000 cP). Spray at 0.5MPa pressure, applying 3 coats (each 0.13-0.15mm thick, total 0.4mm). Fire at 1200℃ with a 20-minute peak hold—ensure the kiln temperature is uniform (±5℃) to avoid gloss variations across tiles.
Q: How to repair scratches on the glaze surface?
A: For minor scratches (<0.1mm), buff with fine-grit sandpaper (2000 mesh) and then polish with a glaze repair paste (our matching High-Gloss Repair Paste, sold separately). For deeper scratches, reapply a thin layer of glaze slurry (0.1mm) and refire at 1180℃ for 15 minutes.
Q: Is it slip-resistant for wet areas?
A: The standard formula has a static friction coefficient of 0.5 (dry) and 0.3 (wet)—for wet areas (e.g., bathrooms, pool decks), add 5% alumina powder to the slurry to increase friction (static friction coefficient ≥0.6 wet), though gloss will drop to 80 GU.
Q: What’s the shelf life of the frit powder?
A: 12 months in sealed, moisture-proof PP bags (stored at 15-25℃, humidity <60%). Once opened, use within 3 months to prevent moisture absorption and clumping.
Q: Can it be used on existing tiles for refinishing?
A: No—this frit is designed for greenware (unfired tiles) and requires high-temperature firing (1200℃) to melt; existing fired tiles cannot withstand this temperature without cracking. For refinishing, use our low-temperature tile refinishing glaze (cures at 120℃).
Q: What’s the difference between high-gloss frit and standard polished frit?
A: High-gloss frit has a higher TiO₂ content (8-10% vs. 5% in standard) and a finer particle size (200-300 mesh vs. 100-200 mesh), resulting in a more intense mirror effect. It also requires stricter kiln temperature control (±3℃ vs. ±5℃ for standard) to avoid gloss inconsistencies.
