3M RP2110
Harmonization Code : 3907.30.00.40 | Epoxy Mold Compounds containing by weight more than 70 % silicon dioxide
Main features
- Aircraft Erosion-Protection Repair
- Controlled 1:1 Cartridge Dispensing
- Ten-Minute Working Window
Product Description
3M Scotch-Weld Repair Paste 2110 is a two-part, 100% solids urethane paste for repairing polyurethane erosion-protection films and coatings. The components dispense from 1:1 Duo-Pak cartridge formats through a static mixer with the 3M EPX applicator. A typical 10-minute work life provides the repair window before the material advances toward cure. It becomes tack-free in about six hours and reaches full cure in 24 hours at 25 deg C. The cured material forms a black polyurethane elastomer with sand and rain erosion resistance, making it suitable for localized repair of compatible aircraft protection systems.
Key features
- Erosion-protection repair: Cures to a black polyurethane elastomer for localized repair of compatible aircraft erosion-protection films and coatings.
- Controlled 1:1 cartridge mixing: Duo-Pak cartridges dispense both components through a static mixer in the specified ratio.
- Ten-minute working window: Provides a typical 10-minute work life before progressing to a 24-hour full cure at 25 deg C.
Applications
Applications include repair of polyurethane erosion-protection films and coatings on helicopter rotor blades, leading edges, engine components, and other aircraft erosion areas.
