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.

APPLICATION

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.
