SURFACE PREPARATION

To obtain good adhesion, remove all traces of oil, wax, grease, dirt, or other contamination. This is done by wiping with a clean oil free solvent. Clean only small areas at one time and wipe dry with a clean cloth before the solvent evaporates. Maintain a clean solvent supply.

MIXING INSTRUCTIONS

When mixing pre-packaged kits, the entire contents of base compound (Part A) and curing agent (Part B) should be used. For small quantities, mix 100 parts by weight of Part A to 10 parts by weight of Part B. Part A and Part B are carefully matched in production for optimum performance characteristics. Care should be taken to assure that the Part B packaged with a given Part A isn't separated and used with a different Part A. The lip of the base compound container should be removed to facilitate mixing. Next, stir Part B in its original container until it is homogenous. Add Part B to Part A and mix thoroughly seven to ten minutes or until uniform in color. Scrape sides and bottom of the container to assure a complete mix. CS 3202 may be mixed by hand or with a mechanical mixer. When using a mechanical mixer, use low speeds since high speeds will generate heat and reduce application life.

APPLICATION

CS 3202 may be applied with a pressure gun or a spatula within the specified application life. Specified application lives are based on the standard conditions of 77 deg F and 50% relative humidity. For every 10 deg F rise, the application life is reduced by one half; for every 10 deg F drop, it is doubled.

CURE

The cure period is dependent on the application life, temperature, and relative humidity. Increased temperature and increased relative humidity will speed cure. Reduced temperature and reduced relative humidity will slow cure. Cure may be accelerated by heating up to 120 deg. F.
