Flamemaster CS 2415 Aluminum Exterior Sealant - MIL-S-38228

CS 2415 is recommended for sealing external seams, depressions and gaps on aircraft to yield weather tightness and achieve aerodynamic Smoothness. CS 2415 is a non-flow material and may be utilized on vertical and overhead, as well as horizontal surfaces. CS 2415 is a Thixotropic, fuel resistant sealant for use on pressurized cabins.

A two component, polysulfide based, aluminum filled, non-flow, filleting material designed for Aircraft sealing. CS 2415 is based on Flamemaster technology, utilizing Permapol P-5 Polymers, an improved chemical modification Of Thiokol LP* polymers.Permapol P-5 polymers are covered under U.S. Patent 4,623,711.

CURE

The rate of cure is affected by temperature and humidity. High temperature and high humidity accelerate the cure and low temperature and low humidity retard it. To hasten curing under adverse conditions, it is permissible to heat the applied compound with infrared lamps or by other convenient means. However, temperatures higher than 120 deg. F may cause sponging or bubbling of the uncured compound and should be avoided. Full cure is obtained in seven days at 77 deg. F and 50% R.H.

MIXING INSTRUCTIONS

CAUTION: This product has a limited application life. Do not mix accelerator and base compound together until ready to use. The accelerator and base compound are carefully matched in production for optimum performance characteristics. The accelerator is packaged in a separate container, but the label designates by batch number which lot of accelerator is matched to which lot of base compound. Care should be taken to assure that the accelerator and the base compound are a designated "match" before the two 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 rim of the container with a can opener to make the mixing and pouring operations easier.
