Disclaimer & Data Tolerance:
The technical data and particle size distributions (PSD) listed above are typical reference values based on internal laser diffraction analysis (wet dispersion). Due to variations in testing equipment, dispersion methodology, and normal manufacturing lot tolerances, these values should not be construed as legally binding product specifications. The exact parameters for any commercial order will be strictly governed by the Certificate of Analysis (CoA) provided with the specific batch shipment. Customers are strongly advised to conduct thorough application testing in their specific binder systems before mass production.
