FRX-03E-1 Urea‑based Water‑Soluble NPK Anti‑Caking Agent

1. Product Overview

FRX‑03E‑1 Urea‑based Water‑Soluble NPK Anti‑Caking Agent is a dedicated liquid additive developed for granular urea‑containing water‑soluble compound fertilizer. It effectively solves severe caking issues caused by high hygroscopicity of urea‑based water‑soluble fertilizer granules in warehouse storage, stacking and long‑distance sea freight.

FRX‑03E‑1 shows stable performance under summer ambient conditions and can be applied directly without pre‑treatment. Slight sediment may occur at low winter temperatures. Heat to 30 ℃ before spraying, sediment will dissolve completely with no negative impact on anti‑caking performance. For maximum anti‑caking effect
FRX‑03E‑1 achieves optimum performance when used together with FRX‑01D series water‑soluble powder additives.

Formulated as a surface‑coating anti‑caking additive, FRX‑03E‑1 forms a protective barrier on fertilizer granule surfaces to inhibit crystal‑bridge generation. It is widely adopted for production and export of urea‑based water‑soluble NPK fertilizers.

2. Core Advantages

‑ Tailored for urea‑based water‑soluble NPK granules, effectively inhibits crystal‑bridge formation and fertilizer caking under high‑humidity storage and maritime transport ‑ FRX‑03E‑1 supports direct application in summer; slight winter sediment disappears after heating to 30 ℃, simple field operation ‑ Best synergistic effect when combined with FRX‑01D series water‑soluble powder additives, further improving long‑term anti‑caking capacity ‑ Forms uniform protective barrier over fertilizer granule surface, suppresses moisture ingress between particles ‑ Compatible with existing cooling rotary‑drum spraying equipment, no equipment modification required ‑ Low dosage, will not change fertilizer nutrient indexes ‑ Provides reliable anti‑caking protection for export‑grade granular water‑soluble fertilizer under tropical sea‑freight conditions

4. Application & Dosage

4.1 Adding Method

Spray FRX‑03E‑1 urea‑based water‑soluble NPK anti‑caking agent evenly on fertilizer granule surface inside cooling rotary drum after granulation, drying and cooling. ‑ Summer: FRX‑03E‑1 can be used directly without heating. ‑ Winter low‑temperature: heat up to 30 ℃ and fully dissolve sediment before spraying, keep stirring during operation.

4.2 Reference Dosage

Recommended addition rate: 1.0‑3.0 kg / ton finished fertilizer. Adjust dosage according to fertilizer moisture, urea proportion, local climate and expected storage cycle. Field trial is recommended to confirm optimal usage.

5. Packaging, Storage & Transportation

Packaging: 200L metal drum; 1000L IBC tote tank for bulk orders.

Storage: Store in cool, ventilated warehouse. Avoid direct sunlight and freezing. Keep container tightly sealed after partial use.

Transportation: Handle with care, keep away from rain and high‑temperature exposure.

6. Frequently Asked Questions

Q1: Can FRX‑03E‑1 work for high‑urea granular water‑soluble NPK?
A: Yes. FRX‑03E‑1 urea‑based water‑soluble NPK anti‑caking agent is developed for highly‑hygroscopic urea‑containing water‑soluble fertilizer granules and delivers stable anti‑caking performance. Better effect can be obtained when matched with FRX‑01D series water‑soluble powder additives.

Q2: Is winter‑time sediment a product defect?
A: No. Slight sediment is a normal physical change under low temperature. Heat to 30 ℃ with stirring, sediment will dissolve completely and product performance remains unchanged. Do not spray without heating in winter.

Q3: How to cooperate with FRX‑01D series water‑soluble powder additives?
A: FRX‑01D powder additive is added during raw‑material mixing, FRX‑03E‑1 liquid anti‑caking agent is sprayed on cooled fertilizer granules. Separate dosing of two products brings synergistic anti‑caking effect.

Q4: Does FRX‑03E‑1 need new spraying equipment?
A: No. It fits standard post‑cooling rotary‑drum spraying system same as traditional anti‑caking oil, no reconstruction needed.
