Application guidance
Confirm the appropriate grade and dosage through application trials. Add the product under controlled mixing conditions and monitor the relevant process parameters to maintain consistent performance.
Quality, packaging and storage
Raw-material selection, moisture, particle size and application-relevant performance values are controlled by batch. Standard supply is available in moisture-protected bags or big bags. Store in a clean, dry area protected from water. Grade, packaging and supply conditions can be adapted to customer requirements.
Technical note: Values shown are typical product targets and not a binding delivery specification. The agreed product specification and certificate of analysis (CoA) for the delivered batch take precedence.
