The document compares properties of polyurea aromatic and polyaspartic aliphatic polyurea coatings. Polyurea aromatic has a very fast working time but requires complex machinery for application, while polyaspartic aliphatic polyurea has an adjustable working time up to 60 minutes and can be applied by simple methods like brush or roller. Polyaspartic aliphatic polyurea provides excellent abrasion resistance and tensile strength with low material wastage and cost, but it is more susceptible to yellowing over time compared to polyurea aromatic.
