description

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 24 hours at 75°F (24°C) (loads on the product should be limited until full cure is achieved). Curing: Dapco 2100 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). Optimum physical properties are developed when the product is cured 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.
