International Classification:

C05G 500

US Classification:

71 6407, 71 6411

Abstract:

This invention relates to polyurethane encapsulated fertilizer particles which exhibit slow-release properties and to a process for their production. The process comprises (1) applying an isocyanate-reactive component or a polyisocyanate component to fertilizer particles, to form coated fertilizer particles, followed by (2) applying a polyisocyanate component or an isocyanate-reactive component onto the coated fertilizer particles to form polyurethane encapsulated fertilizer particles, and, optionally, repeating these steps as many times as necessary to form the polyurethane encapsulated fertilizer particles that contain about 2 to 20% by weight of polyurethane, based on the total weight of the encapsulated fertilizer particles. Alternatively, the isocyanate-reactive component and the polyisocyanate component can be premixed prior to being applied to the fertilizer particles to form polyurethane encapsulated fertilizer particles. Suitable isocyanate-reactive components comprise oleo polyols.

Assignee:

Bayer Corporation - Pittsburgh PA

International Classification:

C05G 500

US Classification:

71 6407

Abstract:

This invention relates to a process for the production of polyurea encapsulated fertilizer particles. These are produced by applying an isocyanate-reactive component which contains at least two amine groups to fertilizer particles to form amine coated particles, and applying a polyisocyanate component to the amine coated particles to form polyurea coated particles. These steps may optionally be repeated in successive order. The resultant polyurea encapsulated fertilizer particles contain from about 0. 5 to 15% by weight of polyurea, based on the total weight of the encapsulated fertilizer particles. Instead of using an amine group containing isocyanate-reactive component, water can be applied first.
