LOCTITE NS5109

Main features

  • High-Temperature Flexible Sealing
  • High-Pressure Sealing up to 34 MPa
  • One-Part No-Mix Application

Product Description

LOCTITE NS 5109 High Temperature Gasket Maker is a one-part, solvent-based gray sealing paste for sealing flanges, threaded connections, fasteners, and gasket assemblies in industrial equipment. The slow-drying material cures by solvent evaporation and remains pliable and flexible from -45 to 315 deg C. It applies without mixing to cork, paper, plastic, and metal surfaces. The high-viscosity paste resists oils, fuels, lubricants, and chemicals in gasket service and seals pressures up to 34 MPa in high-pressure assemblies.

Key features

  • High-temperature sealing: Seals from -45 to 315 deg C while remaining pliable and flexible.
  • High-pressure gasket service: Seals pressures up to 34 MPa in gasket and threaded-connection applications.
  • One-part paste application: The high-viscosity solvent-based paste applies without mixing to cork, paper, plastic, and metal.

Applications

Applications include gaskets, flanges, threaded connections, fasteners, aircraft heating systems, manifolds, pipe fittings, steam lines, gearboxes, and cover plates.

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Physical Properties
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application
