3M 7100170986 | TC2810 1.691 oz White Epoxy Adhesive

Description

3M 7100170986 is a two-part thermally conductive epoxy that is white and filled with boron nitride. It was designed for high adhesion and thermal management in electronic assemblies and power-dense modules. The 3M thermally conductive epoxy adhesive TC-2810 is ideal for potting and gap-filling applications due to its good surface wet-out, thin bond lines, and low viscosity. It cures to a stable, low-outgassing paste with thermal conductivity ranging from 1.0 to 1.4 W/m-K. The cartridge format (1.691 oz / 50 ml) enables precise mixing and dispensing for consistent bond joints. TC-2810’s slight tack allows pre-assembly, while low ionic content preserves circuit integrity—making it a practical white epoxy adhesive and 3M 2-part epoxy adhesive option for thermal interface and structural bonding tasks.

Product Features and Benefits

High thermal conductivity for heat dissipation

TC-2810 delivers 1.0–1.4 W/m-K thermal performance via boron nitride filler, providing measurable heat transfer from components to heatsinks or substrates.

Low viscosity and good surface wet-out

The 3M 2-part epoxy adhesive formula wets complex surfaces and fills micro-gaps for thin, consistent bond lines, ideal for potting, underfilling and thermal interface layering.

Strong adhesion with slight tack for pre-assembly

This 3M white epoxy adhesive has high strength to secure components, and its slight tack allows for positioning prior to final cure, reducing rework during assembly operations.

Low ionic content and low outgassing

The 3M 7100170986 is designed for electronics; TC-2810 minimises ionic contamination and volatile emissions, protecting sensitive circuits and improving long-term reliability.

Practical cartridge size and controlled cure

Supplied as a 1.691 oz (50 ml) two-part cartridge with paste consistency and a 24-hour full cure at 23°C, enabling predictable processing and shorter production cycles.

Frequently Asked Questions

Is TC-2810 available in a 1.75 fl oz size?

The standard cartridge size is 1.691 oz (50 ml); 1.75 fl oz is an approximate commercial equivalent, but confirm packaging SKU for ordering.

Is this product a heat-conductive epoxy?

Yes, TC-2810 is a heat conductive epoxy with boron nitride filler and nominal thermal conductivity of 1.0–1.4 W/m-K.

Does TC-2810 qualify as a high thermal conductivity epoxy?

Yes, its 1.0–1.4 W/m-K range places it in the high thermal conductivity class for filled epoxies used in electronics thermal management.

Is TC-2810 thermally conductive yet electrically insulating?

Yes, the unique formula of the 3M 2-part epoxy adhesive allows for thermal conduction while maintaining electrical insulation and low ionic content, making it safe for use with electronics.
