Comparison with Other Threadlocking Adhesives
Loctite 55 compares favorably with other threadlocking adhesives in terms of strength, temperature resistance, and ease of use.
Adhesive | Bond Strength (psi) | Temperature Resistance (°F) | Viscosity (cP) |
---|---|---|---|
Loctite 55 | 5,000+ | -65 to 400 | 2,000 |
Adhesive A | 3,000 | -40 to 250 | 1,500 |
Adhesive B | 4,000 | -50 to 350 | 3,000 |
As evident from the table, Loctite 55 surpasses the competition in terms of bond strength and viscosity, while maintaining comparable temperature resistance.
Effective Strategies for Using Loctite 55
Surface Preparation: Before applying Loctite 55, ensure that the threaded surfaces are clean, dry, and free from contaminants.
Application: Apply a thin, even layer of adhesive to the male threads using a brush or dip applicator. Avoid over-application, as excess adhesive can hinder proper curing.
Assembly: Insert the male threaded component into the female threaded component and tighten according to the recommended specifications.
Curing: Allow the adhesive to cure for at least 24 hours before subjecting the assembly to vibration or load.
