An introduction to polyaspartic polyurea film formation, applications and selection limits, including its differences from conventional polyurea in reaction speed, working time and outdoor weathering. Actual performance depends on the complete system and test results.
Name and Selected Boundary
Polyaspartic polyurea normally forms through the reaction of a polyaspartic ester resin with an isocyanate component. Comparing it with conventional polyurea requires more than comparing names: check resin structure, usable working time, application method, compatible primer and test conditions.
