DUC-LINE 324″ 100% solids monolithic epoxy coating for concrete pits receiving oily residues with traces of styrene. It is a coating based on modified aliphatic epoxy resins of the type biphenol A liquid base, catalyzed by means of cycloaliphatic amines. The DUC-LINE 324 coating is considered a monolithic elastomeric membrane to protect against contamination and deterioration. This coating was developed with the most advanced technology, so it can be subjected to the onslaught of organic and inorganic acids, denatured alcohol, xylene, perchloroethylene and aqueous acetic acid.
