description
Dapco 2200 is an adhesive, two-component, 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°F (-54°C) to 400°F (204°C) are major considerations. The product can also be used as an insulative and/or ablative heat shield.
features
- Quick Cure

- Service temperature of -65°F (-54°C) up to 400°F (204°C)
- Universal primerless adhesion to diverse substrates
- Good resistance to aerospace chemicals
- Offers non-inhibition curing characteristics against other sealants and adhesives
- Non-Volatile Content of >96%
- Qualified to BMS 5-63, BAMS 552-004, and AMS3374
applications
- Applying: 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 less than 4 hours at 75°F (24°C) (loads on the product should be limited until full cure is achieved).
- Curing: Dapco 2200 is generally cured at ambient temperatures above 55°F (13°C). 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 75°F (24°C) 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 a minimum of seven days for sealing applications and 14 days for faying surface applications at 75°F (24°C) and 50% R.H. Cure may be inhibited by proximity or contact with a variety of materials including old RTV silicone sealant of the tin-cure variety, polysulfide, sulfur, amine and amide compounds, natural, nitrile or other organic rubbers, paper masking tape, plasticizers, lubricants, release agents or solvents.
- Cleanup: Before the material has cured, the excess may be removed using commercial solvent. For optimum removal of silicone residue prior to paint or coating application, Dapco 2000 diluent is recommended.
