Product Description
LOCTITE® ABLESTIK 2600K adhesive is designed for thermal management applications requiring high heat extraction from the die. This adhesive uses a unique suspension system containing silver, thermoplastic and thermoset resin particles suspended in a solvent carrier. Once the material is fully cured and the solvent is evaporated, the adhesive has an extremely high silver loading.
LOCTITE ABLESTIK 2600K adhesive provides very low thermal resistance between chip to case, nearing solder and eutectic-type materials. This low stress adhesive has excellent delamination properties and yields consistent dot sizes with minimal or no tailing. Typically used for high power devices and heat sink attach.
Cure Schedule
- 30 minute ramp from 100°C to 200°C + 15 minutes @ 200°C
- 30 minute ramp from 25°C to 175°C + 1 hour @ 175°C

| Thixotropic index Thixotropic index 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. | 3.5 | ||||||||
| Viscosity 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 | 9,000 mPa.s | ||||||||

| 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. | 68 °C | ||||||||
| Thermal Conductivity 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. | 20 W/m.K | ||||||||
