Description

An ordinary single-layer enamel can be overcoated with a clear coat only before drying to tape and in one color. Enamel 858 gives full gloss as a standalone coating, but within the three-day window before sanding it is turned into a two-layer system. This is convenient for a simple scheme where a white aircraft has a registration number and several stripes, and the decision about a clear coat is made later. Chemically it is a hybrid polyester-acrylic binder with urethane cure on 850 Series toners. The hardener is CM0858SH1, and the reducers are CM0858SR2, SR4, SR6 or SR8. Pot life is 4 hours, the recoat window is up to 72 hours, tape-ready time is 2–12 hours, viscosity is 15–18 s in a No. 2 Zahn cup, and the base is stored for 2 years.

How to choose

If the color is simple and a clear coat is not needed, the single-layer version is enough. For metallics and micas take the two-layer SKYscapes 850 or 855. The Gulfstream system CPS000053 and GAML000033 includes Jet Prep, the Next Gen Chrome Free primer and the urethane filler CM0486707. There are also Cirrus specifications, and in the recommended general aviation systems the enamel is applied over chromium-free and chromated primers and fillers.
