Product Description

Epoxy Resin DH-400S Dry Type Sealant

EXPLAIN

DH-400 is the representative high strength epoxy sealing material intended for the repair and reinforcement of concrete structures. It is designed as crack sealing material for epoxy injection and steel plate reinforcing, and for various other purposes including for the setting of syringe injector. It has an excellent bonding strength with concrete and high crash worthiness.

PULPOSE

Sealing of cracked area for crack repairing, for setting washer and sealing for the reinforcement of steel plate

FEATURE

Thanks to the superior properties of epoxy resin, it maintains an excellent adhesive strength for wide range of materials such as concrete, metal and cement mortar etc.

Chemicals are not dried while they are agitated and can be easily removed with a hand grinder. It is suitable for application to the vertical surface and ceiling because it does not run down.

It is solids by volume 100% which does not contain any volatile matter like solvent, etc and its slow hardening speed makes the work easier.

The fully hardened composition does not cause any chemical action on the reinforcing bars or concrete structures, shows no shrinkage after hardening and maintains stable bondage because of little internal stress.

Compared to cement mortar or concrete, it has an excellent mechanical strength in all respects including compression strength, bending strength and tensile strength, etc. and can be used as sealing materials for steel plate compression injection because it is highly strong and adhesive and designed to withstand high pressure.

APPLICATION

It is designed as a sealing repair product of the cracks without staying power or the joints of concrete structure and plastering mortar. It contributes to the restoration of staying power of the structure by filling (sealing) the large cracks and cut areas with a specially processed epoxy resin of high bonding strength, tensile strength and compression strength. It improves the durability of structures by preventing water leakage from cracks and corrosion of reinforcing bars by the infiltration of harmful gas in the air.Its applications are as follows.

Sealing of cracks of dry concrete structure

Sealing of gap produced by dry cement plastering mortar and tile etc.

Sealing for grouting reinforcement of aged, weakened parts of dry concrete

Sealing for grouting repair of cracks on dry concrete molding products

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.

MATERIAL

1. Reinjector is a mid-low pressure injecting device, upgraded to improve the effectiveness of grouting for crack repairing by incorporating the merits of the high pressure grouting of packer and the merits of syringe injector.
2. Syringe injector is a low-pressure, low-speed grouting device. A syringe injector containing the resin is set on the cracks and the resin is slowly injected with the help of resilience of the rubber band.
As explained above, you can employ various kinds of methods by using numerous grouting devices. The following work guidelines are based on the syringe injector, the representative low-pressure grouting method. You are free to change the materials depending upon the site condition. Please refer to the reinjector method and packer grouting method to learn how to use.
