How does the fluorine content affect the polishing process?
The presence of fluorine in the powder fundamentally alters its chemical reactivity and hardness during application.
Standard fluorine levels (3-7%) can accelerate the polishing rate on certain glass types by actively modifying the surface chemistry.
Fluorine-free (0%) variants are strictly utilized in high-purity applications, such as semiconductor manufacturing, where trace halogens could cause severe contamination.
What is the optimal concentration for mixing the polishing slurry?
The ideal concentration depends heavily on the substrate material and the specific polishing equipment being utilized on your floor.
Generally, a concentration of 5% to 15% by weight in deionized water provides an excellent balance of cutting force and suspension stability.
We recommend starting at a 10% concentration and adjusting based on the observed material removal rate and the resulting surface finish.
Can this powder be used for restoring natural stone surfaces?
Yes, the compound is highly effective for the cold processing and restoration of various hard architectural surfaces.
It easily removes micro-scratches, etching, and dull spots from marble, granite, and engineered stone.
The chemical action of the cerium dioxide helps to create a deep, natural gloss that is vastly superior and more durable than traditional wax or resin coatings.
How should the powder be stored to maintain its efficacy?
Proper storage is critical to prevent agglomeration and maintain the powder's flowability and suspension properties.
Store the material strictly in its original, tightly sealed double-lined packaging.
Keep it in a cool, dry, and well-ventilated warehouse, completely avoiding direct exposure to moisture, extreme humidity, or chemical vapors.
Do you provide support for matching the powder to specific polishing pads?
Absolutely. The synergy between the abrasive powder and the polishing pad is vital for achieving optimal planarization results.
Our technical team can analyze your current polyurethane, felt, or pitch-based pads.
Based on this analysis, we will recommend the precise D50 particle size and formulation code to prevent pad glazing and maximize your operational efficiency.
