TD-ERM2 Epoxy grout is a two (also can be made into a three-component) sub-solvent-free epoxy system, imported saturated epoxy resin, curing agent and a hard filler composed of high-strength, impact abrasion, sticky Results of the new thin solid patching material. Directly to concrete substrates, mainly used to fill the hole in front of and follow-up paint for concrete to fill irregular surfaces, the product has an adhesive fix to both plugging and sealing, corrosion and other features, the infiltration (can penetrate concrete surface). First, the product features 1, thixotropic: thixotropic excellent static state material was easy flow of the gel state, even if applied in the top or side, etc. grooves, cavities within the material will not be deformed, sagging and so on, easy to guarantee construction quality; when subjected to shear force mixing, extrusion, etc., were good flow stream metamorphosis, easy construction operations. 2, the adhesive properties: the main mechanical performance, strong bond with concrete, easy to crack in the adhesive surface. 3, and concrete good match: good anti-aging and anti-carbonation properties, the coating can be synchronized with a concrete deformation at different temperatures, avoiding the large differences in material expansion contraction caused by interface stress is too large and appear coating off the air and cracking. 4, good flexibility: a lower elastic modulus and good flexibility, can improve the impact properties of the cured system, resist deformation by external forces, not easy to brittle fracture. Second, the product uses 1, for 3mm chamfered minor flaws, but also for the concrete surface pores, small cellular, Ma surface, a thin layer of sand lines, and bug fixes as well as concrete seepage, anti-carbonation protection, micro-cracks and appearance beautification closed deal with. 2, for high-speed railway passenger dedicated van beams and orbital plate surface defect repair and after the concrete surface lightly worn over the water (no milk skin surface, fine aggregate exposure, feel rough) patch. 3, mainly used for acid corrosion anti-corrosion construction, acid brick, granite, marble paste. 4, the sealing surface cracks, the cracks in the block process requires the use
