Flamemaster CS 2415 Aluminum Exterior Sealants
Your aircraft will gain better performance and a longer life when you treat it with Flamemaster CS 2415 aluminum exterior sealants from SkyGeek. These airplane exterior sealants are made to fill the grooves, seams, depressions and gaps on aircraft. Through application, you'll achieve a weather-tight seal on your aircraft as well as improved aerodynamic smoothness. Easily coat all parts of your pressurized airplane cabin, as this sealant can be applied to horizontal, vertical and overhead surfaces. CS 2415 is made up of two components and features a polysulfide-based, aluminum-filled filleting material. The sealant will cure faster when exposed to high temperatures and high humidity.

Storage LifeCS 2415 has a storage life of nine months when stored at temperatures below 80oF in the original unopened container. Minor variations may occur to the application properties.
Production matches accelerator and base compound for optimum performance characteristics. The accelerator package is a separate container, but the label designates by batch number which lot of accelerator is matched to which lot of base compound. Assure that the accelerator and the base compound are a designated "match" before the two components are mixed. Proper mixing of all two-component synthetic rubber compounds requires care to obtain a uniform, air free mix. Mechanical mixing is recommended for best results. However, mixing by hand is entirely satisfactory for small quantities. When material is to be mixed in the gallon or smaller sized unit, it is advisable to remove the container lip using a can opener.
The accelerator is first stirred separately to assure even dispersion. Then add the accelerator to the base compound. Mix slowly with a paddle or low speed mixer (70-80 RPM), for approximately seven minutes, until a thorough blend is obtained. In order to insure proper dispersion; scrape paddle, bottom, and sides of container several times during mixing procedure. There is sufficient color contrast between the base and accelerator components; this is to provide a visual safeguard against incomplete mixing.
CS 2415is applied with extrusion gun, putty knife or spatula. Satisfactory performance depends on continuous contact between the compound and the sides of the joint; apply carefully, eliminate gaps, bubbles and voids. Whenever possible, seams and joints should be filled in a continuous operation without layering of the compound. After application, the uncured compound may be smoothed or tooled. Dipping of the brush or tool in water facilitates tooling. Excessive amounts of cured material may be sanded using #400 grit sandpaper. Application life is always measured at temperatures of 75oF and 50% relative humidity.
