DH-207 is a high viscosity epoxy resin with superior adhesion strength and mechanical strength. It is designed to prevent defective injection or packing caused by running resin from injection into large crack. DH-207 prevents defective adhesion caused by running resin from mortar applied to outer wall or injection to tiles, crack hollowing caused as resin infiltrates into the parent body when recovering crack on cement or brick, or leakage to the other side of the penetrated crack

It is used for the repairing of cracks of over 1.5mm when the measured width of a crack is larger than the allowable width in case the target member is structural member, or when the structural stability, durability, waterproof should be considered regardless of the identity of the target member. Applications are as follows.

Repair and reinforcement of cracks in Pc plate, concrete molding products

Grouting reinforcement of aged, weakened parts of concrete

Repair and reinforcement of cracks on slab and upper plate

Grouting of loosened gap of concrete plastering mortar and tile etc

Reinforcement of steel plate when it is used

Grouting for machinery foundation

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.

① It is specially designed to endure high pressure that is applied. Injected resin won't flow backward and this packer is also specially designed not to leak resin around stabilized and fixed packer.
② This is 1 component type high-pressure injection equipment that is specially manufactured to fill on a leakage and fracture spot by using polyurethane foam and epoxy injection material.
The following work guideline provides you with an explanation on the packer grouting method by means of a representative injection device when DH-270A High Viscosity Grouting Material is used. You are free to change the materials depending upon the site condition. Please refer to the reinjector method and syringe grouting method to learn how to use.

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 10~25℃ with no moisture. Store it in cool area. Storing period is about 6 months in sealed condition however it can be corrupted according to storing area and conditions. Preferably use it as soon as possible.
