Urea coating agent

Using the latest generation of solvent-free bio based polyurethane packaging material (national authorized invention patent number: ZL202310002816.7), after coating fertilizer particles, it not only improves the appearance and storage performance, but also has the functions of sustained release, long-term effect, fertilizer reduction and efficiency enhancement.

1. Bio based membrane material, introducing bio based polymer block copolymerization technology, environmentally friendly and biodegradable.

2. High toughness and strong processability, good film extensibility, stretchability, and elasticity, making it less prone to wear and brittle cracking during production, transportation, and fertilization processes.

3. Low viscosity, high spreading and adhesion, suitable for various processes, short coating time and low energy consumption.

4. This coating agent is mainly used for urea, compound fertilizers, potassium fertilizers, etc.

5. Depending on different fertilizers, a fertilizer coating rate of 1.8% to 5.0% can achieve a 60-180 day slow-release period requirement.
