What is Polyurea?
Pure polyurea is formulated as either aliphatic or aromatic.The aromatic polyurea is more tenacious and does not resists UV exposure, causing some discoloration and loss of shine, which is not recommended for applications “face side”. On the contrary, aliphatic polyurea is resistant to UV radiation and it is excellent as a finish coat, because of its raw materials high costs, it makes it a polyurea of higher price range.
