Thermal paste X-23-7921-5, 5g

Shin-Etsu X-23-7921-5 Thermally Conductive Paste is a thermal interface (TIM) designed to fill micro-imperfections between a heat source and a heat sink. It reduces contact thermal resistance, increases heat transfer efficiency, and is suitable for long-term operation in electronic applications. The 5 g package option is designed for service, prototyping, and routine assembly.

Installation and operating instructions

• Before application, clean the contact surfaces from dust, grease and remnants of the original material.
• Apply a thin, continuous layer and use the pressure of the cooler to ensure even distribution
• Remove excess material with a soft cloth.
• Store in a closed container; after opening, consume within a reasonable time according to storage and handling conditions.

Safety notice

• Avoid contact with eyes and prolonged contact with skin; wash hands after handling.
• Keep out of reach of children.
• Do not use on surfaces where contamination of optical or contact surfaces could occur.
