## Questions & Answers

**Q: What is the thermal conductivity?  (W/m/K)  "High thermal conductivity" means nothing.**
A: Super Lube Tech Sheet says "Thermal Conductivity: 0.55 watts/meter K"  http://www.super-lube.com/files/pdfs/Technical_Bulletin_Heat_Sink_Compound.pdf

**Q: Can I use this grease on my engine block heater cartridge?**
A: If you have a dry heater block hole (element does not touch antifreeze inside the block), this is the grease to use. Worked great on my Toyota Camry.

**Q: What is the heat tolerance?**
A: Says on back of tube the temperature range is -40 to 500 degrees Fahrenheit

**Q: Is this ok to use on restaurant equipment? I need to apply some on the heat element of a popcorn maker. It won't touch the food but wanted to be sure**
A: I used it on the temperature probe on the inside of the machine. You should be good with your popcorn machine.

Lo utilicé para algunos aparatos que se notaban muy calientes, uno de ellos se apagaba por sobrecalentamiento, resulta que la pasta térmica estaba completamente seca, desarmé, limpie con alcohol isopropilo, aplique este producto y rearme, nada de problemas ahora, conduce bien el calor y con el paso de aire de ambiente se mantiene a buena temperatura (enfriamiento pasivo). Recomendado!
