Versatile application methods.

Curing Agent Preparation & Mixing:‌

Dilute the water-based isocyanate curing agent to 60-70% solids using a suitable co-solvent (e.g., PGDA or PMA+DBE blend [1:2]) prior to use. Combine Component A (main agent) and Component B (curing agent) and mix thoroughly using a pneumatic or electric stirrer. Subsequently, dilute the mixture with water, typically 5-25% based on Component A weight.

‌Grinding Application:‌

While the system exhibits excellent wettability suitable for grinding, limit grinding time to less than 2 hours and temperature to below 50°C. Exercise caution, as grinding introduces variables that may compromise stability.
