Product Description
LOCTITE® ABLESTIK 2143D is a two-component, medium-viscosity epoxy adhesive for industrial bonding and sealing applications requiring toughness, impact resistance, and electrical insulation. The amber system mixes at a 100:100 resin-to-hardener ratio by weight and bonds most metals, rigid plastics, ceramics, glass, leather, rubber, wood, and concrete. The mixed adhesive has a typical viscosity of 38,000 mPa·s at 25°C and can cure for 24 to 72 hours at 25°C or 4 hours at 65°C. Typical cured properties include a -60 to 100°C operating-temperature range, volume resistivity of 1 × 1014 ohm-cm at 25°C, and aluminum lap shear strength of 15 N/mm².
Key features
- Tough, impact-resistant bonding: The cured epoxy has a typical Izod impact strength of 1.14 ft-lb/in of notch and is documented for thermal-shock resistance.
- Electrical insulation: Typical cured volume resistivity is 1 × 1014 ohm-cm at 25°C, with dielectric strength of 460 V/mil.
- Room-temperature or heat cure: Guideline cure schedules include 24 to 72 hours at 25°C or 4 hours at 65°C.
Applications / Suitable for
- Industrial bonding and sealing
- Bonding most metals, rigid plastics, ceramics, and glass
- Bonding leather, rubber, wood, and concrete
- Assemblies requiring toughness, impact resistance, or low-temperature performance

Mix Ratio

The amount of a constituent divided by the total amount of all other constituents in a mixture
Specific Gravity
1.12
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.
Thermal Properties
Glass Transition Temperature (Tg)
65 °C
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding.
The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
Operating Temperature
-60 to 100 °C
Physical Properties
Thixotropic index
1.0
Thixotropic Index is a ratio of a material s viscosity at two different speeds in Ambient temperature, generally different by a factor of ten.
A thixotropic material s viscosity will decrease as agitation or pressure is increased. It indicates the capability of a material to hold its shape. Mayonnaise is a great example of this. It holds its shape very well, but when a shear stress is applied, the material easily spreads.
It helps in choosing a material in accordance to the application, dispense method and viscosity of a material.

Electrical Properties
Volume Resistivity
1×10¹⁴ Ohms⋅cm
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
