Self adhesive PTFE tape is a type of heat resistant tape made of polytetrafluoroethylene (PTFE) material, which has chemical resistance, non-stickiness and insulation properties. It is often used in industrial, electrical, electronic and other fields to seal, insulation and protection.

Before applying self-adhesive PTFE tape, it is necessary to ensure that the surface to be pasted is clean and dry, so as to ensure the best adhesion effect. Here are some cleaning steps:

1. Remove dirt and oil: Use a clean cloth or detergent to remove dirt, oil, dust and other contaminants on the surface.

2. Remove rust and scale: If the surface has rust or scale, use sandpaper, steel wool or other tools to remove it.

3. Cleaning with solvents: If the surface is difficult to clean, you can use solvents such as acetone, ethanol, etc. to clean, but pay attention to choosing solvents that will not damage the substrate.

4. Dry the surface: After cleaning, use a clean cloth to wipe the surface dry, or use hot air to blow dry.

When using chemical solvents, be sure to pay attention to safety and protection.
