What is Aliphatic Polyurea? – Benefits and Uses of Aliphatic Polyurea Coatings
Defining Aliphatic Polyurea
An ideal solution if you are seeking a brightly colored or lining coating that will not fade in extreme sunlight. Aliphatic Polyurea is the ultimate solution for lagoons and swimming pools since the entire waterproofing elastomeric coating system of 3 mm thickness is entirely aliphatic in nature. Aliphatic polyurea is a type of polyurea formulation known for its highly superior UV stability, colour retention, and weathering resistance. Unlike aromatic polyurea’s, which can yellow and degrade under sunlight, aliphatic polyurea maintains its appearance and structural integrity even when exposed to harsh UV conditions. Aliphatic polyurea coatings eliminate the need of a thin aliphatic top coat over the aromatic polyurea coating (for colour stability) especially in lagoons and swimming pools; which can easily de-bond or crack due to differences in physical properties and failure to adhere to overcoat windows of both the products due to negligence or poor workmanship; especially in harsh climatic or marine environments.
Key Properties of Aliphatic Polyurea
Aliphatic polyurea is often used as a topcoat or finish coat in protective coating systems. It offers high gloss retention, chemical resistance, and flexibility while providing long-term durability in exposed environments. This makes it especially suitable for outdoor applications such as lagoons, swimming pools, roofs, façades, marine structures, and high-traffic public areas.
Where Aliphatic Polyurea is Used
Common uses of aliphatic polyurea include architectural coatings, decorative waterproofing systems, pedestrian walkways, lagoons, swimming pools and any surface exposed to direct sunlight. Because of its UV stability, aliphatic polyurea is often chosen as the final layer in multi-coat polyurea systems, ensuring aesthetic and functional longevity.
