Directions for Use
Ensure surfaces are clean, free from dust, grease and other contaminants before use. Mix well by hand or jar
roller before using.
A uniform coating of 0.05 mm to 0.255 mm thickness should be applied For high volume applications stencilling
or screening is recommended, for the best results use a 61 (or less) threads per inch screen. Ensure that the
entire interface is covered to avoid hot-spots from forming. Any excess paste squeezed out during the mounting
process should be removed. In most cases allow for up to a 20% reduction in thickness due to material retention
on a screen printer and another 20% reduction for solvent evaporation. For example: Initial thickness on a screen
= 0.2mm, 20% retain on screen = 0.16mm, 20% reduction from solvent evaporation = 0.13mm.
TPM350 Thermal Phase Change Material
In Stock
TPM350 is one of Electrolube’s latest high-performance product innovations in our thermal interface material range.
It is designed for easy application via screen printing, containing a small amount of solvent which evaporates after application to leave a cured material in place. This eliminates the mess associated with thermal pastes or greases. The material changes viscosity (phase change) once it reaches its activation temperature of 50°C ensuring efficient thermal transfer during operating conditions, minimizing contact thermal resistance, and returning to its cured state once it cools down again.
