Whats the difference between aromatic and aliphatic polyurea systems?
Actually there are two different types of aliphatic polyurea systems currently on the market. One is the typical high pressure/temperature sprayed systems and the other is what is known as a “polyaspartic polyurea” type system. This polyaspartic system is different in that it uses an ester based resin component and has a longer pot life. It can be hand applied using close nap rollers; brushes; rakes or even airless sprayers. The aspartic systems are not the high build coating typical of the “hot spray” polyurea systems. The typical aromatic polyurea systems must be processed through high pressure, heated plural component pumps and sprayed through an impingement type spray-gun. This is true also for the aliphatic version of this type of system, the primary difference being the color stability of the aliphatic systems.
