Features
- Fast curing: the highly reactive secondary amine groups can provide a touch-dry time of approximately 5 minutes at room temperature when used with an HDI trimer.
- A solids content of 97±2% supports low-VOC and near-solvent-free coating systems. Viscosity of 60-100 mPa·s at 25 degrees Celsius provides good flow, sprayability and leveling.
- The resulting coatings balance appearance, toughness and long-term protection.
- Provides system stability and formulation flexibility for different coating and elastomer systems according to the required properties.
- It can serve as either the main resin or a chain extender in the R component of spray polyurea elastomer systems, giving formulators additional flexibility.
Applications
