Wet type injection

RE-200 is an epoxy resin which can be used for wet crack part . Lt is usually used for wet part or area with moisture of concrete structure and it is 100% non-solvent with same viscosity of the injection of ultra low viscosity. There is no shrinkage problem and it can penetrate into minute cracks and it has good quality product with strong adhesive power and excellent mechanical strength.

Features

1. lt is non- solvent product.
2. lt can be used for dry crack part we well as for wet crack part.
3. lt can penetrate into any minute crack as it has ultra low viscosity.
4. lt has excellent adhesive strength on wet crack part.

Uses

lt is used for crack part of wet surface or with moisture or wet part of structure of underground (ex. Subway tunnel , tunnel, underground parking lot, water tank etc.)

General property

Mechanical property

How to use

lt should be used with after mixing resin with hardener with correct mixture ratio as it is two liquids phase. Pot life may be vary from temperature and the amount of mixture. Lt the amount of mixture is large or the temperature of the place is high, pot life and hardening time becomes fast. lf possible, use small amount of resin and hardener when injecting with structural injector or single liquid phase grouting injection pump (SGI-100, SGI-200) and use the mixture as soon as possible without delay. Particularly, make a mixture in small amount for injection in summer and increase the temperature of the resin in winter. For smooth injection , make sufficient air-vent in injection.

1. When injecting using structural injector (refer to standard specification), weigh the resin and hardener correctly (resin 1kg and hardener 0.5kg) and put about 30cc of mixture into structural injector after mixing well with electric mixer then inject the mixture after connection with installed pedestal (refer to low pressure injecting method).
2. When injecting using single liquid phase grouting injection pump (SGI-100, SGI-200) , weigh the amount of resin and hardener correctly (resin 1kg , hardener 0.5kg ) and mix them well with manual or electric mixer and then pour the mixture into the container of injector and inject them through packer or mighty injector installed at crack part by operating the switch of the equipment (refer to high temperature injection method).
3. When injecting using two liquids phase grouting injection pump, pour resin and hardener into each container of the equipment and check if resin is mixed with hardener well and then inject them through packer, mighty injector or port installed at crack part

Equipment, instrument and cleaning agent

Use structural injector, mighty injection, PORT , single liquid grouting injection pump (SGI-100, SGI-200) and two liquids grouting injection pump. Clean the equipment or tools used immediately after working with toluene, acetone, MEK or epoxy thinner. Fill the injector with oil after using.

Precautions

1. Please wear proper safety equipments including helmet, protective glasses, gloves and working cloths when handling the agent.
2. Wipe out immediately and wash with soaping water when skin is stained with the agent.
3. Please show a doctor if there is eruption of skin by staining with the agent.
4. install a ventilator at working place to get fresh air.
5. Keep correct mix ration when mixing resin and hardener in case of two component type grouter.
6. Clean out instruments or equipment used for working with thinner etc.
7. Mix smaller amount of resin in summer as its pot life, drying time, hardening time may differ by temperature or mixing amount. Increase the temperature of resin in winter season. Pot life: Time period of work with the mixture of resin and hardener . Drying time: Time period from the property of mixed resin begins to change to the time of hardening. After this time, we can not work with the mixture. Hardening time: The time to get mechanical strength as the agent hardens completely ( it should be at least 7 days and final strength can be measured at this time.)
8. Do not use if it is below than 5℃ except unavoidable situation.
9. Please refer to MSDS (Material Safety Data Sheet) for proper handling.

How to keep

Keep it dry and cool place without moisture after sealing the cover to prevent contacting with the air. proper keeping temperature is 15~30 ℃ keeping period of the liquid is 6 months. However, use the agent as soon as possible as it may deteriorate by keeping condition.
