Fills cracks in concrete structures less than 0.2mm by self-penetration
AT380 is a solventless epoxy resin adhesive that fills and fills minute cracks of 0.2 mm or less in concrete structures.
Use
- Penetration bonding to fine cracks of 0.2mm or less including microcracks in concrete structures.
- Primer to prevent concrete pieces coming off, continuous fiber sheet bonding.
- Ground treatment for concrete protection and waterproofing.
- Tack coat of cement mortar and resin mortar.
Features
Excellent penetration |
It penetrates not only downward but also upward and sideways by capillary action. |
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. It satisfies the standards of Japan Water Works Association regulations "JWWA K 143" and can be applied inside water pipes. |
Excellent economics |
Self-penetration only by application by capillary action eliminates the need for conventional injection equipment. 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.
施工方法

使用方法
- Remove dust and oil on the construction surface.
- Measure the main agent and curing agent at a ratio of 2: 1 (by volume) and stir well while paying attention to air entrapment.
- Mix at once so that it can be used up within the pot life.
