Silicone Thermal Grease
Non-Curing Silicone Thermal Grease ZLA-4304
ZLA-4304 is a white silicone thermal grease rated at 1.5 W/m·K, with the same soft, easily spread consistency as the entry grade (penetration 300).
It stays a paste in service, so the interface can be reworked, and it does not corrode the metal or component surfaces it touches.
Density is 2.5 g/cm³; oil bleed and volatile loss are 0.3 % or less after 24 h at 200 °C.
