LOCTITE ECCOBOND E 1216M
- Snap Cure
- Non anhydride curing chemistry
- Excellent adhesion and strength
LOCTITE ECCOBOND E 1216M is an innovative epoxy capillary flow underfill, designed for high-volume assembly operations requiring a very fast flowing underfill that fully cures in a single reflow cycle, but is stable enough to be easily shipped and used in large-volume cartridges (up to 20 oz). That's because this is a board-level underfill for underfilling larger components so it is typically dispensed in relatively larger volumes.
LOCTITE ECCOBOND E 1216M passes NASA outgassing standards and is specifically formulated to eliminate anhydride-type curing agents for those users who prefer to work with anhydride-free products.
- Snap or Inline Cure - 3 minutes @ 165°C
- Fast Cure - 4 minutes @ 150°C
- Low-Temperature Cure - 10 minutes @ 130°C
| 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.

Work life @25°C
Work life is the amount of time we have to work with a material until it is no longer able to be easily worked and applied on a substrate.
It is based on the change in viscosity and it can rely on the application requirements.
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
The viscosity of a material can be decreased with an increase in temperature in
order to better suit an application
| Volume Resistivity
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.
| Glass Transition Temperature (Tg)
Glass Transition Temperature (Tg)
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.
| Thermal Conductivity
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance.
Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.
