An asphalt composition comprising 0.1 to 10.0 wt.-% monomeric methylene diphenyl diisocyanate (MDI) based on the total weight of the composition, wherein the monomeric MDI is carbodiimide modified and wherein the weight percentage of 4,4'-MDI in the carbodiimide modified monomeric MDI is in the range of from 65 to 85% and the weight percentage of carbodiimide is in the range of from 15 to 35% in the carbodiimide modified monomeric MDI; wherein at least 18% by weight based on the total weight of the composition are particles with a sedimentation coefficient above 5000 Sved in a white spirit solvent.

Asphalt composition comprising monomeric MDI as thermosetting reactive compound

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.

An asphalt composition comprising 0.1 to 10.0 wt.-% based on the total weight of the composition of a thermosetting reactive compound selected from the group consisting of polymeric MDI, epoxy resins and melamine formaldehyde resins, wherein at least 18% by weight based on the total weight of the composition are particles with a sedimentation coefficient above 5000 Sved in a white spirit solvent.

Asphalt composition comprising thermosetting reactive compounds

A coating, system comprises 30 to 90 parts by weight of a bioresin component and 10 to 70 parts by weight of an isocyanate component, based on 100 parts by weight of the coating system, and has a percent solids of greater than 60%. The bioresin component comprises an acrylic polymer and a biopolyol formed from a natural oil. A method of forming a coating on a substrate with the coating system comprises the steps of combining the bioresin component and the isocyanate component to form a reaction mixture having a percent solids of greater than 60 percent, applying the reaction mixture onto the substrate, and curing the reaction mixture to form the coating on the substrate.

Coating system

Method of forming an encapsulated fertilizer that includes the step of providing a core particle. The core particle includes a fertilizer and has an outer surface. The method further includes the step of applying an isocyanate component directly to the outer surface of the core particle. The isocyanate component has isocyanate functional groups. The method further includes 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 includes polyurea linkages and may further include polyurethane linkages.

Method of forming an encapsulated fertilizer

A composite body is provided that includes a rigid polyurethane foam shell and an elastomeric polyurethane layer disposed over the rigid polyurethane foam shell. The rigid polyurethane foam shell defines a cavity within the composite body. The rigid polyurethane foam shell has a closed cell content of at least 70% and comprises the reaction product of a first isocyanate component and a first isocyanate-reactive component in the presence of a blowing agent. The elastomeric polyurethane layer is disposed over the polyurethane foam shell. The elastomeric polyurethane layer comprises the reaction product of a second isocyanate component and a second isocyanate-reactive component. A method of forming the composite body includes the step of molding the rigid polyurethane foam shell, demolding the rigid polyurethane foam shell from the mold, and applying an elastomeric polyurethane composition upon the rigid polyurethane foam shell after demolding to form the elastomeric polyurethane layer.
