Why It Matters
Hygroscopic NPK/urea granules absorb moisture and fuse into bridges in storage and blending equipment; need an anti-caking flow aid or conditioning coating
Solution Approach
Hygroscopic NPK/urea granules absorb moisture and fuse into bridges in storage and blending equipment; need an anti-caking flow aid or conditioning coating RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Application Workflow
1
Application & Agronomic Review
Define the use (crop input, adjuvant, soil amendment, post-harvest) and the agronomic, regulatory, and tank-mix requirements.
2
Input & Grade Selection
Match the surfactant or adjuvant, nutrient source, chelate, or formulation aid to the active, water quality, and label.
3
Compatibility & Rate Trial
Confirm tank-mix compatibility, dose, and stability, and size packaging (jugs, drums, totes, bulk) to the season and logistics.
4
Field Validation
Validate efficacy and crop safety in field trials, and lock the spec and supply plan for the season.
Recommended Chemistries (2)
Amorphous silica
CAS 7631-86-9
Specialty Additives
Thickening / Rheology
Fine amorphous silica coats granule surfaces and adsorbs surface moisture, physically separating particles so they don't bridge or cake
Melting Point: 1710 °C Boiling Point: 2230 °C at 760 mmHg Density: 2.2

Calcium Carbonate
CAS 471-34-1
Mineral Fillers & Pigments
Color / Pigmentation
Finely milled calcium carbonate is a classic internal conditioning/dusting agent: it coats hygroscopic NPK/urea granules, occupies inter-particle contact points, and adsorbs surface moisture so granules stay free-flowing instead of fusing into bridges
Melting Point: 825–1339 °C (Decomposes) Boiling Point: Decomposes Density: 2.7 to 2.95
