HCR-IND is effective for all-purpose descaling and scale prevention, cleaning and degreasing, and caustic neutralization for the majority of industrial applications. HCR-IND has similar solubilizing abilities to strong acids with a premium HSE profile so it can be effectively used in place of conventional strong and weak acids such as hydrochloric, nitric, phosphoric and citric.
