How to Choose the Right Polyaspartic Resin
Cycloaliphatic Polyaspartic Resins
Selection Principles
Cycloaliphatic polyaspartic resins generally offer better overall performance, especially in hardness, weather resistance, chemical resistance and mechanical properties.
Fast-cure grades normally provide better weather resistance and chemical resistance than slow-cure grades.
Fast-cure grades can be used with HDI trimer for low-temperature or ultra-low-temperature curing, and can also be used with prepolymers in waterproofing systems.
Slow-cure grades are generally not recommended for these systems because of the risk of slow curing, incomplete curing or lower-than-expected performance.
