Composition

KEM PR-5840 is a product of appropriate Nonionic surfactants in petroleum solvent. KEM PR-5840 is basically a detergent substance that joins little bubbles into big ones. By this procedure big bubbles are less stable, and are releasing their trapped gas easier than small ones.

KEM PR-5840 is suitable for middle to high temperature refinery operations.
