Concrete cracks with epoxy seam glue 
 Product Use 
 Perfusion> the 0.05mm structural micro-cracks and 0.5mm wide structural cracks, or the mortar, concrete, brick panels hollowing gap grouting reinforcement processing. 
 Features 
 This product is concrete structural micro-cracks in grout deal with special glue. Low viscosity epoxy resin, polymer emulsion with various additives, active additives modified refined. 
 Can be used wet or dry environment, with a resin body shrink, high strength, good toughness, to adapt to the characteristics of strong 
 Technical performance 
 Viscosity (Mpa.s/20, ° C) :350-500 
 Compressive Strength (Mpa): ≥ 50 
 Tensile strength (Mpa): 20 
 Bond strength (Mpa): 3.0 
 Shrinkage rate (%): <0.9 
 Using the ratio of information 
 A: B weight ratio: 4:1 
 Operating time / 18 ° C: <50 
 Can be fed with slit width (mm):> 0.5 
 Features: for wide concrete cracks, high viscosity, dry or slightly wet environment. 
 Note: This weight is more than suitable for a 13-22 ℃ environment, if more than 22 ° C, may be appropriate to reduce the amount of the B material (such as A: B = 4:0.8), in order to avoid heating too fast. Less than 13 ° C, may be appropriate to increase the amount of material B (such as A: B = 4:1.2), in order to accelerate the reaction rate. 
 Packaging and storage 
 1, the packaging of the product specifications: A material 4kg; B, feed 1kg. 
 2, the product is sealed and stored in the shade, the shelf life of 12 months. No exception can continue to use more than 12 months. 
 Process 
 1, with a magnifying glass, the correct observation of crack width to determine the crack length; 
 Primary treatment: Clear cracks in the surface of dust, oil; 
 3, to determine the injection port: generally in accordance with the 20-30cm distance to set up an injection port, as far as possible the location of the injection port located in the cracks wider opening than the smooth flow of parts, taped, and set aside; 
 4, closed cracks: Sealing plastic coated scraping along the crack surface, leaving the injection port; 
 5, install the plastic base: Peel off the tape on the sprue, Sealing rubber base will stick in the injection port; 
 6, the erection of grouting: the resin injected into the hose with a good, fitted with resin grout tightened at the base; 
 7, grouting: release the spring, confirm that the inject state, such as grouting resin can be added and then continue to inject. 
 After the removal of grout injected finished: to reduce the injection rate, make sure not into the plastic base will be blocked with a plug; 
 9, grouting, resin curing, knocked the base and plug, clean the surface of sealing glue.
