SEMI RIGID INJECTION RESIN FOR SEALING LEAKING CRACKS AND JOINTS.
One component, closed cell, hydrophobic, water reactive, solvent and phthalate free, low viscosity polyurethane injection resin for stabilisation and water cut-off of large water leaks. In contact with water the SPETEC will expand and set as a permanent water seal inside the crack or joint.
1、 Process description
Spray repair technology of Spetec wet shield refers to the method of pipe repair in which the stirred resin slurry is sprayed onto the inner wall of the pipe through the high-pressure nozzle to form a solid inner wall of the pipe.
Damaged Utility repaired by Spetec spray method
2 、Material Characteristics
Resin type and properties
Suitable for wet and dry surfaces
High viscosity
Simple blend color control
Hard and durable coating
Complete water tightness
Easy to overlap. The new coating will cover the coating perfectly and stick to the existing one.
Full thickness (1-3 mm) in one workflow
Good adhesion to concrete, brick, steel and wood
Component A (Red) and Component B (Grey)
