DHP-4000 is Hydrophobic Type and 2 component type quick setting Foam. It is specially manufactured for crack leakage and where water pressure is severe. Due to field conditions, you can control the reaction speed by using catalyst. It foams in 15 seconds at minimum. Therefore, it is applied where it requires quick setting such place like civil engineering field and underground structures. Since it is hydrophile property, it even reacts with small amount water. And the foam that the reacting is finished will not be influenced by water and moisture Hydro

Use for the cracks water stop of concrete structures and waterstop treatment for joint areas, wet areas and areas of considerable leaks, and can be used in the following areas.

Waterstops for leaking section of basement parking lot and underground concrete structure.

Waterstops for cracked leakage section of structure that has vibration.

Waterstops for leakage of concrete joint section.

Waterstops for leakage section where humidity and dryness is mixed up together.

Waterstops for severe leakage section of concrete structure.

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.

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 urethane thinner should be used when cleaning. If the Foam is smeared on your skin during the performance, wash it immediately with flowing water. Used injection equipment should need to be stored after filling up the hose, pump and medical fluid container with Engine Oil and hydraulic Oil.

- 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. This product is packed with nitrogen gas. Once seal is removed, then use it as soon as possible.
