Silicone Thermal Grease
Non-Curing Silicone Thermal Grease ZLA-4310
ZLA-4310 is a 3.0 W/m·K grey silicone grease for components that run hot for long periods.
Oil bleed is 0.15 % or less after 24 h at 200 °C, lower than the general grades, and the paste is firmer (penetration 245).
Like every grade in the range it does not cure, so assemblies can be opened and the grease renewed.
