ONE COMPONENT FLEXIBLE FOAM
SW-PU V is one component flexible foam. As the polyurethane water-stop resin behind structure of one-part hydrophilic type, it reacts with water to foam the closed cell-type foam or gel. In the reaction with the excessive amount of water, it foams a high-elastic gel. And in a reaction with small amount of water, it will foam a high-elastic flexible gel.
The gelling time varies according to surrounding temperature and the amount of water It is a high quality PU grout used in America and Europe where foam and gel-type. SW-PU V is mainly used as the water-stop resin behind vibratory structures.
