Jet Prep Pretreatment

A new chrome free pretreatment now available

The New Sol-Gel Metal Pretreatment Offers Excellent Corrosion Protection and Adhesion for use with aircraft.  

ANDOVER, KANSAS - October 27, 2023 — Sherwin-Williams Aerospace Coatings has introduced the new Jet Prep™ Pretreatment (CM0220P01), a chrome-free, water-based, translucent, sol-gel metal pretreatment solution designed specifically for the aerospace industry. The two-component pretreatment kit provides superior adhesion and corrosion protection over aluminum substrates, and pairs with aerospace-grade corrosion-protective epoxy primers and topcoat paint systems.

No special equipment is required to utilize Jet Prep Pretreatment – simply spray, brush, or wipe on the product. Application is made even easier due to a slightly pigmented (blue) tint to provide a visual cue; a flat appearance when dry to confirm successful application; and an extended pot life of up to 12 hours. Plus, with no surface preparation required after application, Jet Prep offers a cost effective and less labor-intensive solution compared to traditional coating processes.

Jet Prep delivers a high-quality chrome-free pretreatment solution to the aviation industry. It also provides applicators the ability to apply a complete Sherwin-Williams chrome-free system from substrate to topcoat.
