DifGel HD 2.0 Acrylic Resin allows for waterproofing injections while water is present and under high pressures. With its stability and ability to gel at any setting time, DifGel is perfect for almost any leak.
• CGI Resin does not pollute the water table and is environmentally freindly
• CGI Resin has the following characteristics:
• Slight order
• Non-flammable
• Solvent Free
• Soluble in water
• Low Viscosity
• CGI Resin is non-toxic to the operator and environment
• CGI Resin is injected through dual lines of a variable pressure pump, easily controlling the quantities used.
• CGI Resin has a low flow resistance due to its viscosity. This enables operators to not only seal cracks but to also seal the smallest capillaries.
• CGI Resin contains a short-lived color dye enabling the operator to visually control the injections. A few minutes after the injection (and full polymerization) the dye completely dissapears leaving no visible stain.
• CGI Resin is chemically a non water-reactive product. Its' polymerization does not invlolve water, producing better control of the setting time.
• After injection, CGI Resin becomes a gel, in a time which can be adjusted chemically from a few seconds to a few hours.
• CGI Resin setting time is not affected by polluted or salted water.
• CGI Gel is water and gas proof.
• CGI Gel will remain water tight even if water dissappears and reappears over time.
• CGI Gel will resist even permanent water pressure.
• When in contact with water, CGI Gel will swell, due to its hydrophilic properties. These properties are incorporated into three(3) dimensional polymer frameworks, ensuring that even if the cross section of the joint or cracks change, the gel remains intact.
• Water does not induce chemical deterioration but on the contrary acts as a partner, further maintaining the gel in a condition of maximum expansion.
• CGI Resin is stable with alkalines to 12ph, therefore not attacked by wet concrete.
• CGI is insensitive to diluted acids, bases, and salts.
• CGI gel is insoluble in water, solvents and hydrocarbons.
• CGI gel is inert and unable to damage bitumen, membranes, joint-ribbons, construction materials and concrete.
• CGI Resin is non-biodegradable and therefore cannot be a growth aid for fungi, microorganisms, mold or bacteria.
• CGI gel is very adherent and highly elastic.
• CGI Resin can withstand concrete works and/or ground deformations.
• CGI gel can withstand freezing temperatures.
• CGI gel has no effects on any materials in which it may come in contact.

Chemical Tests
CGI Resin was completely polymerized with a setting time of one (1) minute. The test sample was kept at room temperature for a period of 42 days. The degree of discoloring, consistence, and dissolusion were determined. The test sample was characterized as either "stable" or "unstable".
