For a blade tip repair, the company suggests Loctite UK 1351 B25 (Structural Bonder) GL-certified, cartridge-dispensed polyurethane with 50 minutes of working life. Loctite UK 1370 B10, a polyurethane putty, has a work life of 10 minutes and can be sanded in 30 minutes.
Repairing rotor-blade-tip damage provides an example of catalog contents. Such damage can be significant and structural in nature, requiring a new tip or a structural patch for the repair. To apply:
• Surface should be clean, dry and abraded.
• Damaged substrate material should be removed from the repair area.
• Bond in the structural patch using Loctite UK 1351 B25 structural bonding adhesive.
• Sand or grind the edges of the patch.
• Mix the Loctite UK 1370 B10 Putty and apply using a trowel to smooth the product over the damaged area.
• Sand after 30 minutes.
