The polymer coated urea (PCU) produced by Risso Fertilizer Factory has national patent technology in Thailand, and the product meets the Q/DYC01-2015 standard.
Polymer coated urea (PCU) consists of a core layer and a coating layer. The core layer is granular urea, and the coating layer is two layers. The inner layer is a shrink layer, and the outer layer includes polyurethane and raw materials polymerized by polyols and oil substances with co-bonded double bonds.
Polymer coated urea (PCU) is a safer and more efficient nitrogen source. Its release rate is mainly determined by temperature and moisture through the micropores in the coating, which is usually called temperature-controlled diffusion and osmotic pressure. It can also be called a smart release nitrogen fertilizer that can provide nutrients to your plants throughout the season. The shelf life of PCU urea is 3-12 months.
