Title: Raising the barrier to rust: Properties of different talcs compared in corrosion testing.
Authors: Veli Kilpeläinen (Mondo Minerals), Alejandro Gutierrez (VLCI), Sander van Loon (VLCI).

Talcs with different properties were evaluated as anticorrosive pigments. Differences in performance could be found much more rapidly and clearly by using EIS methods than by salt spray testing. Pure, platy low oil absorption talcs gave excellent barrier properties in heavy duty protective coatings without the use of any other anticorrosive pigment.
