POLYUREA

WHAT IS POLYUREA?

Polyurea is truly a remarkable coatings, linings and joint sealant technology. It is being used successfully for so many different applications today.

polyurea

Polyurea coatings and linings are more commonly applied over concrete and steel for corrosion protection and abrasion resistance. They also have tremendous advantages over conventional materials for joint fill and caulk applications due to their fast set nature, high elongation and durability/abrasion characteristics.

A great technology that boasts so many different formulations and physical property ranges. There are pure polyureas (defined by the PDA) and there are hybrid polyurea systems, each possessing their own characteristics and advantages.

Polyurea cannot solve your protective coating or joint fill needs by itself. It must be specified and installed in combination with proper surface preparation and primers, correct manufacturer’s material formulation, proper equipment, quality control inspection and trained applicators.
