CONTACT GEL FOR ULTRASONIC TESTING Russian patent published in 2022 - IPC G01N29/28 

FIELD: non-destructive ultrasonic testing.

SUBSTANCE: invention is intended for non-destructive ultrasonic testing. The substance of the invention lies in the fact that the contact gel for ultrasonic testing includes, wt.%: up to 20.0 glycerol and propylene glycol; up to 1.0 triethanolamine; up to 1.0 carbomer, which is a rare polymer of acrylic acid; up to 10 sodium phosphates and silicates, which are Na₅P₃O₁₀, Na₂SiO₃, Na₃PO₄; up to 0.1 fullerenols based on a mixture of C₆₀ and C₇₀fullerenols; water - the rest up to 100.

EFFECT: providing the possibility of creating a universal contact gel for non-destructive testing, which has a high and stable speed of propagation of ultrasound, high acoustic permeability and at the same time high viscosity, which can be used in a wide temperature range, has bactericidal, antifungal and anti-corrosion properties and high adhesion to various materials, is safe for human and environment and convenient to use.
