Title:
POLYURETHANE RESIN FORMING COMPOSITION FOR AGRICULTURAL MEDICINE COATING MATERIAL
Document Type and Number:
Japanese Patent JP2021017563
Kind Code:
A
Abstract:
To provide a polyurethane resin forming composition for agricultural medicine coating material giving excellent slow release property to a fertilizer.SOLUTION: A polyurethane resin forming composition contains a hydroxy group-containing compound component (A) and a polyisocyanate component (B), in which the (A) contains a hydroxycarboxylic acid (A2) and/or a hydroxy sulfonic acid (A3), and the (A) contains a castor oil polyol (A1), and/or the (B) is a polyurethane resin forming composition (P) for agricultural medicine coating material containing an isocyanate group-terminated urethane prepolymer (U) containing the castor oil polyol (A1) and a polyisocyanate (D) as constituent monomers. It is preferable that the molar ratio of the hydroxyl group of the hydroxyl group-containing compound component (A) to the isocyanate group of the polyisocyanate component (B) [(hydroxyl group)/(isocyanate group)] is 0.5 to 2.0.SELECTED DRAWING: None
