Two components spray-up elastic coating applied in complicated weather.
Component A is a half prepolymer through the reaction between hydroxyl terminal compounds and isocyanate.
Component B is a mixture consisting of amino terminal resign and amino terminal chain extender, not including hydroxy acrylic resin and activator.
Where to use:
Railway girder concrete bridge surface;
All constructions and water conservancy projects;
Chemical vessels;
Cabins and floors of ships;
Water resistance and corrosion resistance of decks and channels;
