LOCTITE 5772
Harmonization Code : 3910.00.00.90 | Silicones in Primary Forms; Others
Main features
- Activator-Free Stainless Steel Sealing
- Low-Halogen Sensitive-Metal Formulation
- UV-Fluorescent Product Identification
Product Description
LOCTITE 5772 is a one-part, medium-strength anaerobic thread sealant developed for sensitive metal threaded fittings where low halogen and sulfur content are important. The yellow thixotropic liquid is particularly suitable for stainless steel and can be used without surface activation on stainless steel. Chlorine and fluorine content are no more than 200 ppm, and sulfur content is no more than 200 ppm. At 25 deg C, typical specific gravity is 1.09 and typical cone-and-plate viscosity is 3,000 to 12,000 mPa s at 36 s^-1. After 24 hours at 22 deg C, typical breakaway torque is 6.4 N m on M10 stainless steel nuts and bolts and 17 N m on M10 black-oxide steel fasteners by ISO 10964.
Key features
- Activator-free stainless-steel sealing: Particularly suitable for stainless steel without the need for surface activation.
- Low halogen and sulfur content: Chlorine and fluorine content are no more than 200 ppm, with sulfur content no more than 200 ppm.
- UV fluorescence: The yellow product fluoresces under UV light in the uncured state.
Applications
Sealing metal threaded fittings, including sensitive metals such as stainless steel and titanium where low halogen and sulfur content are required.
