Tempfix™ is a non-conductive thermoplastic hot melt adhesive resin, especially formulated for SEM studies. It does not contain solvents and is stable under high vacuum. Its adhesive characteristics appear in the 40-120°C range. Melting starts at 40°C and it becomes a thin fluid at 120°C, displaying a wide viscosity range. It has a very smooth surface and can be used in SEM imaging without interfering background.
Preparing specimens requires a hot plate or heating block, aluminum sheets of 10 x10 x 0.25mm used as specimen mounts, a metal cooling block and a pin stub type specimen holder with a side clamping screw on top. The aluminum sheet is warmed up to about 120°C and a small amount of Tempfix™ is applied and smoothed over the sheet. Excess resin is removed. After the sheet has cooled down, Tempfix™ is a solid smooth plastic surface. Particulate or other small samples may be sprinkled or applied on the solid plastic surface and the sheet is gently heated above 40°C to the desired viscosity. Use temperature to control viscosity and how far the particulates "sink" into the adhesive.
Remove the sheet and cool it quickly on a metal block. Delicate specimens will likely not suffer heat damage. A thin conductive coating (sputtering or evaporation) might be needed for optimum imaging results. The aluminum sheet with the specimen can either be mounted on the supplied pin mount adapter with clamping screw or can be mounted on a specific SEM mount with a conductive adhesive carbon tab.

The shelf life of cyanoacrylate glues (and epoxies) can be extended by storing them at lower temperatures; -20°C. At lower temperatures, the adhesive becomes very viscous and the speed of chemical reactions is practically reduced to zero. It will keep the adhesive stable for years. Before use, let the adhesive thaw with the container sealed to avoid condensation into the adhesive.

low temperature model Glue Guns provide practical adhesive uses for certain applications. Leo Barish’s papers referenced below and others not mentioned cover this subject.
A thermoplastic glue stick is used with a gun-type design to melt the glue and allow its application, for example, to an SEM specimen mount. Heavier and/or larger specimens, which might move during study when held with a tape or disc adhesive, will hold firmly in place when this type of adhesive is used to "seat" the specimen. Carbon coating the specimen and the adhesive will permit an electrical discharge path. A lower temperature range (100° to 120°C / 212°- 248°F) is preferable, such as our model 16068 to avoid possible damage to heat sensitive specimens. (Normal temperature for standard high temperature glue guns is in the 190° to 210°C / 374° to 410°F range). The glue hardens quickly so the specimen should be positioned promptly upon glue application. If repositioning is required, the glue may be softened with the Glue Gun. Porous specimens such as felt with a poor discharge path may accept a track of glue over its surface to reduce such static. Granular specimens may be sprinkled onto the hardening surface.
