Handling & Storage:
Store between 5°C and 40°C, protect from frost, weathering, and direct sun exposure. Once opened, reseal immediately. Surface drying and slight sedimentation are normal but do not affect performance if solids content meets specifications. If necessary, filter the product before use. Use within 6 months from delivery.
Processing Instructions:
Add under stirring at the end of formulation, after binder incorporation. Achieve thickening effect by bringing the pH of the formulation to 8.5 to 9 using an alkali solution (e.g., sodium hydroxide, ammonium hydroxide, amines).
