| Résumé : |
Epoxy (EP) and moisture-curing polyurethane (PU) systems are mostly used today as reactive primers for preparing substrates before floor coating or installing parquet and other floor coverings. Our comparative tests show that primers based on polyaspartics (PAS) have properties that are comparable to these established systems but cure much faster. We demonstrate the practical benefits of using this new system in an exampleof coating the concrete floor of a supermarket in Greece. |

- Moving on from the status quo
- Excellent adhesion to the substrate
- Fast adhesive application now possible
- Resistant to plasticisers
- Short waiting time, highest productivity
- And to top it all off, low emissions
