Easy to treat after use!! Contacted medium for ultra-sonic testing “Mitaecho”

To personnel handling the quality management/ultra-sonic testing: Do you have some problems in the removal of contacted medium?Please try using the contacted medium for ultra-sonic testing, “Mitaecho”, a Mitajiri original.

“Mitaecho” is new type of contacted medium for ultra-sonic testing which is completely soluble in water and makes a thin film after drying.
“Mitaecho” is optimal for testing steel-frame bridges, buildings, and structures, having the following characteristics.

  • Treatments during the process are simplified.
  • It is optimal for testing diaphragms in columns.
  • It is rustproof.
  • Because it makes a thin film, it will not cause weld defects.
  • It does not make the factory dirty.
  • It decreases the damage of ultra-sonic testing machines.
  • It helps lower costs.
  • It can be cleaned up with water after drying, if necessary.

“Mitaecho” can be selected in accordance with use.

“Mitaecho” (A contacted medium of non-glycerin paste)

This is a new type of contacted medium for the nondestructive testing of iron-frame buildings, bridge/steel frames, industrial plants, and steel- frame buildings, and is easy to handle after use.
We have 3 kinds of products; “Mitaecho-S” for general use, “Mitaecho-A” for freeze resistance in winter, and “Mitaecho-P” with anti- spatter agents.

ミタエコー
  • “Mitaecho-S”for general use
  • “Mitaecho-P”with anti-spatter agent
  • “Mitaecho-A”with freeze resistance (can be use down to -20℃)

※When using the anti-spatter agent made by W Co. Ltd, we recommended “Mitaecho-P” for non-gelatinization.
※“Mitaecho-A” contains 5 times the humectant formulation ratio as compared to “Mitaecho-S (P)”
※“Mitaecho-A” characteristics: better acoustic effects, higher viscosity (less dripping), better resistance to freezing.
