Sonotrace 30 is a medium‑viscosity, glycerin-free ultrasonic gel ideal for flaw detection and thickness gauging in clean, low-reactivity environments. Engineered to minimize halogens and sulfur content, it suits low‑melting‑point metals and nuclear/aerospace specifications, offering excellent corrosion inhibition, efficient surface wetting, and extended working time thanks to humectants that slow drying. It’s water-washable, silicone-free, and cost-effective for broad inspection use cases.
