DH-EM30 is a product of high adhesive strength and outstanding physical strength, manufactured in the form of mortar by mixing epoxy resin with silica sand and aggregate. It is widely used for the flooring work and overall repair work of various industrial buildings because it is hardening quickly and not easily discolored,very strong and highly durable.
It provides enough adhesive strength for concrete or reinforcing bars due to the high adhesive strength of epoxy resin.It does not produce any cracks (poor interfacial adhesion) caused by the volume reduction, for it has a stable weather-resistance regardless of natural condition of high or low temperatures, and almost no shrinkage resulting from hardening reaction.It offers the compression, bending and tensile strengths which are 3 to 10 times higher than those of cement mortar or concrete. It hardens in about 18 hours and gives the compression strength of 200~300kg/cm within 28 hours. (Based on the normal temperature of 23℃/ 5mm thickness)It is not affected by external impact, vibration or tensile strength, for it provides a perfect reinforcement to low strength and aged surface strength of new or old concrete.It offers a superior anti-corrosion effect, for it is abrasion resistant and chemical resistant against acid, alkali etc, almost incomparable to those of cement mortar. The thickness of floor can be freely adjusted and joints are absent. It is an excellent flooring material of high durability and abrasion resistance, which gives extra smoothness to the floor. (Non-slip finish is also available, if needed)Repair and reinforcement of poorly worked parts or weakened parts of concrete structuresReinforcement of floor base of airport or pierReinforcement of floor base of factory or large machine as well as the floor on which heavy machinery is operating.Flooring of power plant and substation of subway.Bottom reinforcing filler of dust proof fastening devices of subway.Bottom reinforcing filler of dust proof fastening devices of railway.Hardening time for the appearance of hardening properties.(based on the temperature of 23℃)- 10~12 hours after application : good for pedestrians.
- 18~20 hours after application : good for light weight vehicles.
- 48~72 hours after application : good for large heavy weight vehicles.

Pot Life The period of time during which you can work without a change in viscosity after resin and hardener are mixed.Tack Free The state of hardening in which you can lightly touch the mixed resin with your hand, but the hardened material
does not stick.Hardening Time The time it takes for the mixed resin to be hardened enough to realize about 80% of final mechanical strength.Limitation on the workWork shall not be allowed when the ambient temperature of the job site goes out of the range of 5℃~30℃ or the humidity is over 85%. Work is not allowed for the area where concrete is wet or set with more than 10% moisture in it or polymerized. To prevent the condensation of moisture, the surface temperature of surface temperature must be higher than the dew point at least by 3℃E and the relative humidity shall be lower than 85%. As this product is two-component chemical which hardens at normal temperature, you have to mix the main material with the hardener based on exact weight. The mixed chemical is greatly affected temperature, volume of mixture and pot life. Pot life and hardening time will be shortened if the main material and the hardener are mixed in large volume or used in high temperature or used while the temperature of chemical is high. Therefore, you have to mix in small volume in summer and artificially raise the temperature of resin in winter to improve the working efficiency. 
Surface Treatment- Remove laitance, dust, oil, moisture and other foreign substances of lower surface of concrete.
(Unless impurities are completely removed, de-lamination can occur due to poor adhesion)
- Smooth the lower surface by using polisher, sand blast, sand grinder and wire brush etc.
- The surface should have fine ruggedness like sandpaper in order to ensure maximum adhesiveness.Primer coating- Weigh the primer main material and the hardener according to the mixing formula and stir it with electronic blender and
pour it in the mixing can and stir it again for 5 minutes. (You can start mortar work before full hardening because DH-EM30
is an epoxy resin of non-solvent type. When you use epoxy primer, you have to start mortar work only when primer is
completely hardened)
- Evenly apply the stirred primer to the lower surface with a roller or a brush.
- If there exists oil on the lower surface during primer coating, primer may produce something like water droplets.
So, please never fail to remove oil before you resume primer coating work. (For the surface whose absorption is excessive,
please apply primer coating two times to prevent loss of mortar due to the infiltration into the surface and the possibility of
poor adhesion)Application- Mix DH-EM30 in the weight ratio of 3:1 (main material 3: hardener 1) in a separate container. Mix the combined chemical for
2~3 minutes with a vibration blender. Please make sure that the chemical, including some sticking to the wall of the container,
is mixed fully in the mixing container.
- Blend well the mixture of DH-EM30 with silica sand in the ratio of 1:4 (resin 1: silica sand 4) for 3~4minutes with an electronic
mixer.
- Fill the surface to be repaired with the mixture of DH-EM30 and silica sand and press it down so that no gap is produced
in-between and pay attention so that no indents are produced on the top layer.
-DH-EM30 is usually not diluted by a solvent because it is a solvent-free epoxy resin. Your special attention is necessary
because excessive dilution may cause a delay in hardening process and lead to poor strength and defects like cracks etc.All the equipments and tools that are used for this operation should be cleaned when the operation is finished. Detergent such as M.E.K, Acetone, Xylene, Toluene and epoxy thinner should be used when cleaning. If the Foam is smeared on your skin during the performance, wash it immediately with flowing water.- When you treating medical fluid, make sure you wear protective helmet, goggle clothes and other protective devices.
- If the medical fluid is smeared on your skin, wash it off immediately and clean up with soapy water.
- All the hand tools and equipments that are used for this operation should be cleaned with thinner thoroughly.
- If you are working in sealed room, then make sure to conduct constraint ventilation for clean air.
- If the medical fluid is smeared on your skin and causes skin trouble, then you should go see specialist for prescription.
- If the temperature is below 5℃, then you must artificially raise up the temperature of medical fluid. This way you can get proper
Pot Life.
- If the atmosphere temperature is high and the area is humid, Pot Life of medical fluid quickens. On the contrary, Pot Life will
slow down in low temperature area.
- Be aware of it before you conduct the operation.Recommended temperature for storage is 5~30℃ with no moisture. Store it in cool area. Storing period is about 12 months in sealed condition however it can be corrupted according to storing area and conditions. Preferably use it as soon as possible.
