LOCTITE 962T

Main features

  • Thixotropic Application Control
  • High-Strength Joint Sealing
  • Heat-Resistant Sealing Service

Product Description

LOCTITE® 962T™ is a one-component, high-strength anaerobic sealant designed for sealing and securing close-fitting cylindrical metal assemblies where resistance to product migration is important. The thixotropic red methacrylate ester liquid cures when confined between mating metal surfaces in the absence of air. Typical applications include engine block cup and core plugs, water-pump seals, hub-and-shaft assemblies, and other high-strength metal sealing applications.

Key features

  • Thixotropic non-migrating application: Helps limit movement of the liquid sealant after it is applied to the substrate.
  • High-strength cylindrical sealing: Seals and secures closely fitted metal plugs, shafts, hubs, and related assemblies.
  • Heat-resistant cured performance: Delivers 13.8 N/mm² compressive shear strength in the reported hot-strength and heat-aging tests.

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
