Description
Product Overview
The Hzutloer Copper Conductive Grease is engineered for superior electrical performance in high‑temperature environments. Formulated with fine copper powder dispersed in a high‑quality silicone base, the grease offers exceptional conductivity and thermal stability up to 1100 °C. Packaged in a compact 4.53 × 3.46 × 2.4 in. container weighing just 3.53 oz, it is easy to store and apply. Certified by the manufacturer Hzutloer, this product ranks #16 in Automotive Electrical Greases on Amazon, reflecting its strong market acceptance.
Usage
Designed for a broad range of applications, this grease excels in battery connector maintenance, circuit board repair, electrolyzer assemblies, and general automotive electrical systems. Apply a uniform 0.2 mm layer to clean, dry contact surfaces; the conductive medium fills microscopic gaps, ensuring consistent current flow. Ideal for technicians, hobbyists, and OEM engineers who need a reliable solution for high‑heat or high‑current scenarios.

FAQ
What temperature can the grease withstand?
The formulation is rated for continuous operation up to 1100 °C, making it suitable for high‑heat environments such as engine bays and power electronics.
Is the grease safe for use on plastic components?
While optimized for metal contacts, a thin layer will not harm most engineering plastics. Avoid excessive application on non‑metal parts to prevent unwanted residue.
How often should the grease be reapplied?
For most applications, reapplication every 12‑18 months is sufficient, or sooner if the contact shows signs of wear or corrosion.
Can this grease be used for high‑current connections?
Yes, the copper content provides low resistance paths, supporting high‑current loads typical in automotive and power‑tool circuits.
Does the grease require curing time?
No special curing is needed. Once applied, it becomes conductive immediately, though full thermal stability is achieved after the component reaches operating temperature.
