MasterRoc MP 304
Fast-reacting, highly flexible acrylic resin with adjustable reaction speed for permanent water sealing
How does MasterRoc MP 304 work?
MasterRoc MP 304 product is a highly reactive two-component acrylic sealing resin with a low viscosity for good penetration. The product cure quickly, forming a highly flexible hydrogel with excellent swelling/re-swelling properties. Because of its excellent elongation and flexibility, MasterRoc MP 304 product is able to compensate for minor movement of cracks. MasterRoc MP 304 product retains its excellent swelling property in the presence of water, even after dry periods.
