What is the difference between 1K and 2K polyurethane?
Here's the short answer:
1K (one-component) polyurethane like Bona Mega EVO cures by evaporation, while 2K (two-component) like Bona Traffic HD uses a chemical crosslinker for a much harder, more durable film. FSA Network floor sanders choose 1K for standard residential and 2K for high-performance applications. Compare at floorsandingaustralia.com.
