Sirgel Resin HTW-627 is a urethane-modified epoxy resin dispersion in water that is nonionic and typically has an epoxide equivalent weight of 540. Mechanically stable and with a modest viscosity, Sirgel Resin HTW-627 is supplied at a nominal 60 percent nonvolatiles. There are no organic solvents found. Due to its 100% water reducibility, Sirgel Resin HTW-627 offers a broad latitude for viscosity reduction. Because of the thixotropic nature of this dispersion, spindle speed will affect viscosity values.
