Request Information
DAPCO™ 2200 is an adhesive, solvent free, thixotropic silicone paste. DAPCO 2200 is most commonly used as a coating, sealant, or filleting material in the construction, repair and maintenance of all types of aircraft. The product can be applied using a variety of methods and is especially useful where fire resistance, exposure to phosphate ester fluids, and/or exposure to extreme temperatures -65 ºF (-54 ºC) to 400 ºF (204 ºC) are major considerations. The product can also be used as an insulative and/or ablative heat shield. The product is available in kit sizes of 2.5 oz and 6 oz injection kits.

Applications

Applying

 N/A The substrate must be free from contamination, i.e. dirt, oil grease, etc. Clean the surface by wiping with a suitable solvent/cleaning agent and dry thoroughly. Handling strength is achieved in <4 hours at 72 ºF (25 ºC) (High loads on the product should

Curing

 N/A DAPCO™ 2200 is generally cured at ambient temperatures above 55 ºF (13 ºC). Moisture helps develop final properties (a relative humidity ranging between 30-70% is preferred). Product reaches a hardness of 30 shore A in 4 hours at 72 ºF (22 ºC) and 50% R.H, allowing for quick repairs and fast "fly away" times. Full cure is achieved in 48 hours, however optimum physical properties are developed when the product is cured for seven days at 72 ºF (22 ºC) and 50% R.H.

Cleanup

 N/A Before the material has cured, the excess may be removed using DAPCO™ 2000 diluent.
