エアスプレーによる吹付け施工を可能にすることで、大幅な工期短縮を実現

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.

Use

  • 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.

Features

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.
