Surface Preparation |
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. DAPCO™ 1-100 Primer is required for adhesion to most metallic substrates. |
Application and Curing Information |
N/A DAPCO™ 2900 is a 2-part sealant supplied in standard aerospace injection kits; machine mixing of the kit is recommended for optimum performance. The mixed sealant is non-slumping and can be readily applied to vertical and overhead surfaces. |
