Our industry experience began in 1998 with Dinol’s aerospace corrosion-inhibiting compounds, commonly called CICs, and specialized removers. Dinol’s aviation business later became part of Chemetall®. Chemetall subsequently joined BASF in 2016 and today continues as the surface-treatment business of Surventis.

Dinol’s AV-series products addressed different corrosion-control needs throughout an aircraft. In this historical technical presentation, AV8 is described as a thin-film product with exceptional penetration into seams and overlapping metal structures. AV30 provided a heavier protective film and replaced an earlier AV8 and AV100D treatment arrangement in certain lower-lobe applications.

AV15 represented the next development. It was intended to provide both penetration and durable corrosion protection across broader areas of newer aircraft, reducing the need to use different CIC products in different aircraft zones. The presenter continued to recommend AV8 for certain maintenance applications on older aircraft, while anticipating a larger role for AV15 on newer aircraft and in future maintenance programs.

“The product was ready before the standard was written.” The presenter later explained that the developing Boeing requirement would leave Dinol “absolutely alone again.”

The presentation explains that AV15 had completed laboratory, spray-application, and production testing while final written approval and the corresponding Boeing standard were still being prepared. In context, “absolutely alone again” describes AV15 as positioned for the developing requirement and, at least initially, without an equivalent approved competitor.

That product heritage continues today within Chemetall and Surventis. NALTIC is proud to carry forward nearly three decades of familiarity with these aerospace products, their applications, and the customers who rely on them.
