When it comes to industrial-grade chemicals that offer versatility, cost-efficiency, and global demand, Diammonium Phosphate (DAP) ranks high on the list. Identified by CAS No. 7783-28-0, DAP is not only a vital agricultural fertilizer but also an essential ingredient in numerous industrial processes worldwide.
Whether you’re a chemical distributor, manufacturer, or global trader, understanding the benefits and market potential of DAP can open new opportunities for your supply chain and revenue stream.
Diammonium Phosphate(DAP) application:
Phosphorus fertilizer for sale is generally used as the base fertilizer. Under the same conditions, the higher the soil available phosphorus content, the lower the fertilizer efficiency. The suitable dosage range of phosphorus fertilizer for several main crops on the general phosphorus deficiency soil is: Phosphorus fertilizer (P2O5) (4-6) kg for grain crops, sweet potato, potato and cotton, peanut, rape, soybean, jute, tea tree (3-5) kg, watermelon (2-4) kg, tobacco (1-3) kg, sugarcane (6-8) kg, and fruit trees (0.2 to 0.3) kg per plant. When it is found that crops show the symptoms of phosphorus deficiency, phosphorus fertilizer is sprayed on the leaf surface to make phosphorus enter the object through the stomata or cuticle on the leaf surface. Rice, wheat and other gramineous crops can be used at 2% to 3% concentration, rape, vegetables can be used at 1% concentration. It can also use 0.25% concentration of potassium dihydrogen phosphate to spray after the dew dries in the morning or before the dew in the evening, which has a significant increase in production.
What is Diammonium Phosphate (DAP)?
Chemical Name: Diammonium Hydrogen Phosphate
Chemical Formula: (NH₄)₂HPO₄
CAS Number: 7783-28-0
HS Code: 31053000
DAP fertilizer is a white, crystalline, water-soluble salt that combines ammonia and phosphoric acid. It’s highly valued for its high nutrient content and non-toxic, non-flammable nature, making it ideal for both agricultural and industrial markets.
Why Industrial Buyers Choose DAP (7783-28-0)
While DAP is a household name in agriculture, its industrial applications are equally significant and growing. Here’s why industrial buyers and global traders are stocking up:
1. Fire Retardants
DAP is used as a flame retardant additive in the manufacture of fire-resistant materials. Its phosphorus content helps slow the spread of flames in textiles, construction materials, and electronics.
2. Metal Finishing & Surface Treatment
In the metal finishing industry, DAP serves as a phosphating agent, aiding in corrosion protection and surface preparation before painting or coating.
3. Fermentation & Food-Grade Applications
Used as a yeast nutrient in brewing and fermentation processes, DAP ensures faster and more efficient microbial activity. It’s commonly found in the food and beverage industry, especially in wine and beer production.
4. Water Treatment & Detergents
Due to its buffering properties, DAP is an active component in water softeners, boiler treatment chemicals, and industrial cleaning agents.
