概要
AT448 is an epoxy resin adhesive for integrating new and old concrete joint surfaces. Air spraying is possible, which contributes to a significant reduction in the process. It can be used as a primer when casting concrete or ultra-high strength concrete.
ポイント
用途
- Bonding joints between old and new concrete and mortar.
- Adhesion of steel plates and anchor bolts for aerial and wet concrete structures.
- Injection and repair of cracks, joints, junkers, etc. in aerial and wet concrete structures.
- Ground treatment for concrete protection and waterproofing.
- Tack coat of cement mortar and resin mortar.
- Protective material for painted floor.
特長
|
Excellent workability |
Workability is improved by spraying with air spray. |
|
Excellent economics |
従来の塗布工法に比べ工程短縮が図れ、工費縮減・工程短縮に寄与できます。 |
|
High adhesion |
By applying it to the joint surface of new and old concrete, it has adhesive performance to break the base material. |
|
Low shrinkage |
Since it does not contain volatile solvents, there is almost no cure shrinkage and there is no load on the building. |
施工方法
- Apart from spraying by air spray, it can also be applied by application.
- The Standard construction volume by spraying is 1kg / m².
使用方法
- Remove dirt (dust, oil, etc.) on the construction surface.
- Measure and mix the base agent and curing agent in a 2: 1 ratio (by volume) and mix thoroughly, paying attention to air entrapment.
- Mix at once so that it can be used up within the pot life.
- Please perform the construction in an environment with a temperature of 5 ° C or more.
