The technical specifications of Water Activated Hydrophobic Polyurethane Pre Polymer are as follows:
Mix viscosity at 25 degrees centigrade /77 degree F: 250 mPa.s
Volume increase: max. 1:20
Density [20 degrees centigrade /68 degree F]: app. 1.1 kg/l
Spec. gravity of the cured foam: app.0, 05- 0.1 g/cm³
