Self-penetration into cracks in concrete structures, even in upward and sideways applications
AT388 is a solvent-free epoxy resin adhesive that fills and fills cracks in concrete structures. By applying with a brush or roller along the cracks, it penetrates and adheres to the fine cracks of 0.05 to 0.5 mm even in upward application and 0.05 to 0.8 mm in horizontal application by the capillary phenomenon, which is a conventional low pressure injection method. This is a new alternative method.
Use
- Penetration bonding of fine cracks including micro cracks in concrete structures.
- Can be applied to ceilings and walls (vertical surfaces) by application.
Features
Excellent penetration |
Due to the capillary phenomenon, it penetrates not only downward but also upward and sideways. |
High adhesion and durability |
It has excellent adhesive performance not only on dry surfaces but also on wet surfaces. In addition, it shows high tensile strength and bending strength, and has excellent durability. |
Low shrinkage |
Since it contains almost no solvent, there is almost no cure shrinkage, and no load is applied to the applied frame. |
High security |
It emits no toxic gas during combustion and can be applied inside buildings. |
Excellent economics |
Due to the capillary action, it penetrates itself just by applying, eliminating the need for conventional injection devices. Therefore, the number of construction days and construction costs can be reduced. |
* Simply apply with a brush or roller, and the adhesive will penetrate the cracks due to capillary action.
Cost reduction effect
Compared with the conventional method, the construction cost is less than 1/2 and the process can be greatly reduced!
施工方法
使用方法
- Remove dust, oil, etc. from the construction surface.
- When calculating the ratio of base agent to curing agent by volume ratio, weigh in 2: 1 and mix thoroughly, paying attention to air entrapment. (When measuring by weight, measure and mix the base agent: curing agent at 7: 3.)
- Mix at once so that it can be used up within the pot life.
