Abstract: 100% solids polyurethanes having improved physical properties in terms of Shore hardness, tear strength, elongation at break and/or tensile strength are realized through the introduction of 100% solids hydroxyl-functional acrylics in combination with the hydroxyl-functional polyether and 100% solids isocyanate-functional compounds. When an aromatic isocyanate is used, the isocyanate-reactive component includes from 5 to 70% by weight of a hydroxyl-functional polyether having a weight average molecular weight ranging from 180 to 6,500 g/mol, and 30 to 95% by weight of a hydroxyl-functional acrylic. When an aliphatic isocyanate is used, the isocyanate-reactive component includes from 40 to 70% by weight of a hydroxyl-functional polyether having a weight average molecular weight ranging from 180 to 6,500 g/mol, and 30 to 60% by weight of a hydroxyl-functional acrylic.

Abstract: A method of forming an encapsulated fertilizer comprises the step of providing a core particle. The core particle comprises a fertilizer and has an outer surface. An example of the fertilizer is urea. The method further comprises the step of applying an isocyanate component directly to the outer surface of the core particle. The isocyanate component has isocyanate functional groups. An example of the isocyanate component is an isocyanate-terminated prepolymer. A specific example of the isocyanate-terminated prepolymer is one comprising the reaction product of a diphenylmethane diisocyanate (MDI) and a polyol. The method further comprises the step of reacting the isocyanate component with ambient moisture to form a layer disposed about the core particle to form the encapsulated fertilizer. The layer comprises polyurea linkages. The layer may further comprise polyurethane linkages. For example, the layer may be in the form of a polyurea/polyurethane layer when the isocyanate-terminated prepolymer is utilized.

Abstract: Se provee un cuerpo compuesto que incluye una cubierta de espuma de poliuretano rígido y una capa de poliuretano elastomérico dispuesta sobre la cubierta de espuma de poliuretano rígido. La cubierta de espuma de poliuretano rígido define una cavidad dentro del cuerpo compuesto. La cubierta de espuma de poliuretano rígido tiene un contenido celular cerrado de al menos 70% y comprende el producto de reacción de un primer componente de isocianato y un primer componente reactivo de isocianato en presencia de un agente soplador. La capa de poliuretano elastomérico está dispuesta sobre la cubierta de espuma de poliuretano. La capa de poliuretano elastomérico comprende el producto de reacción de un segundo componente de isocianato y un segundo componente reactivo de isocianato. Un método de formar el cuerpo compuesto incluye el paso de moldear la cubierta de espuma de poliuretano rígido, desmoldear la cubierta de espuma de poliuretano rígido desde el molde, y aplicar una composición de poliuretano elastomérico sobre la cubierta de espuma de poliuretano rígido después de desmoldear para formar la capa de poliuretano elastomérico.
