Sonotech Soundsafe

High Performance Ultrasonic Couplant

Soundsafe® is a high-performance, general-purpose ultrasonic couplant for flaw detection and sizing, thickness gauging, flow metering and acoustic emission testing. This medium viscosity gel couplant is well known for its outstanding performance, excellent corrosion protection, thixotropic properties and comprehensive range of specifications and approvals. Soundsafe is Pratt & Whitney approved and meets nuclear grade specifications for halogen and sulfur levels.

Soundsafe® is available in the following sizes:

  • 1 gallon cube
  • 5 gallon cube
  • 55 gallon drum

Features

  • Wide range of specifications and approvals
  • Great surface wetting for fast, even coverage
  • Thixotropic gel
  • Non-toxic, non-irritating formula
  • Increase acoustic impedance reduces surface noise
  • Clings well to most vertical and overhead surfaces
  • Highest corrosion inhibition
  • Provides good transducer lubrication
  • Slower drying for extended inspection time
  • Nuclear grade
  • Aerospace approvals
  • Hydrogen embrittlement testing

How It Works

Step 1: Apply Couplant

Apply a small amount of couplant to the transducer or inspection area before measurement.

Step 2: Removal

Remove couplant immediately after inspection before the couplant dries with water rinse or a combination of water rinse and brushing.
A difficult-to-remove film may form if the couplant is allowed to dry before removal. Remove film by pressure washing, wire brushing or immersing the part in water until the couplant rehydrates and can be washed or brushed off.

Step 3: Storage

Store couplant in the original container. Do not freeze. Store out of direct sunlight. Keep container closed when not in use. Never put unused couplant back into the original storage container. If pumps or valves are used to dispense bulk couplant, wash them thoroughly between drums to avoid contaminating new product.
