摘要：
Spray polyurea elastomers and reaction systems and methods for making the same. The spray polyurea elastomers are prepared with a prepolymer formed by reacting a low 2,4null-isomer content MDI with an MDI reactive component. This prepolymer is blended with a high 2,4null-isomer content MDI to form a quasi-prepolymer. The quasi-prepolymer is reacted with an amine resin to form polyurea elastomers.
