Deformable & Composite LCM
Liquid Expanding Curing Agent for Drilling Fluids
A pale-yellow to brown transparent liquid expanding curing agent with good water solubility and controlled expansion. It disperses rapidly in the mud, swells on contact with water and cures into a dense, high-strength barrier that seals formation fractures and stabilizes the wellbore without impairing mud performance.
