Intense is Activator +.
Most of these coverstocks have reactions between urethane and reactive.
More traction in dry than reactive, less than particle. Less reaction off dry than reactive but more than urethane.
I believe based on description of original Inferno that these coverstocks are engineered to have what ever the stuff is that makes a urethane a reactive urethane.

PS Columbia just came out with their version of this coverstock.
PPS did this stuff all start with the Soaker at Dynothane?
