ECONOgel’s reduced surface tension provides fast wetting.

ECONOgel is glycerin and silicone free.

ECONOgel has good ferrous corrosion inhibition and is compatible with most metals, plastics and composites.

ECONOgel is completely salt stable. It will not thin with corrosion salts, marine environments or highway infrastructure subjected to de-icing salts.

ECONOgel ER has a slower evaporation rate at ambient to elevated temperatures and a broader operating range.

Environmental and operator friendly. No formaldehydes or nitrates or nitrites.

Removal: Wash with water or wipe with paper or cloth rag before couplant dries. If couplant has dried, pressure wash or use brush and running water.

ECONOgel™

ECONOgel is the most economical water soluble NDT Ultrasonic Couplant. 

ECONOgel ER (Extended Range) is the most economical  water soluble NDT ultrasonic couplant with a low freezing point, slow evaporation rate and high operating range. Compatible with most metals, plastics and composites, with good ferrous  corrosion inhibition.
