-40℃~130℃ UV Detectable Electrical Contact Grease Equvalent Klüber KR 44 22 for Automotive Sensor

YBS-KR 44 22 is a professional-grade special lubricant dedicated to electrical contact components, developed by Klüber. Adopting synthetic hydrocarbon base oil and lithium soap thickener, the product features stable grease texture, excellent oxidation resistance and wide temperature adaptability. Built-in UV fluorescent indicator enables intuitive inspection of coating uniformity through ultraviolet light, greatly improving production quality control efficiency.

This contact grease is specially optimized for low-contact-pressure weak-current signal contacts. It can effectively inhibit micro-motion oxidation and fretting corrosion of copper, tin and silver-plated contacts, avoid poor electrical contact caused by long-term operation, and maintain stable and reliable electrical conductivity. Meanwhile, it optimizes the operating feel of switches and connectors, reduces friction loss, and significantly improves the cycle service life of electronic and electrical components. It is compatible with most plastic materials, no corrosion or damage to precision electronic parts, and is a reliable lubrication and protection solution for automotive and industrial electronic contact systems.

Operating Precautions

- Strict Application Range: Only suitable for weak-current signal contacts with low contact pressure, prohibited for high-current power contacts to avoid electrical safety risks. - Control Coating Thickness: Thin coating is the standard. Excess grease accumulation will cause poor contact and signal failure. - Material Compatibility Verification: It is necessary to conduct a small-area compatibility test on rubber and special elastomer materials before batch use to avoid material corrosion and aging. - Standard Storage: Store in a cool, dry and sealed environment, avoid high temperature, humidity and direct sunlight, and use up within the shelf life.

How To Use

■ Clean gears and remove old lubricant before application.
■ Apply grease evenly to gear teeth and contact surfaces.
■ Use an appropriate amount to ensure full coverage without excess.
■ Apply manually or through a lubrication system.
■ Run equipment at low speed after application to ensure proper distribution.
