Putting PU Oil Steps for Rubber Keypad

The process of putting PU oil on a rubber keypad involves a few simple steps. Let’s take a closer look at each of them:

Step 1: Prepare the Rubber Keypad

Before applying PU oil, it’s crucial to clean the rubber keypad thoroughly. Use a mild detergent and water solution to remove any dirt or residue. Gently scrub the keypad with a soft-bristled brush, ensuring you reach all the crevices.

Step 2: Dry the Keypad

After cleaning the keypad, allow it to air dry completely. Alternatively, you can use a lint-free cloth to pat it dry. Make sure there is no moisture left on the surface before moving on to the next step.

Step 3: Apply the PU Oil

Now it’s time to apply the PU oil to the rubber keypad. Follow these instructions:

  1. Place a small amount of PU oil on a lint-free cloth or a soft sponge.
  2. Rub the oil onto the keypad surface, applying gentle pressure.
  3. Ensure an even distribution of the oil across the entire keypad.
  4. Pay extra attention to the edges and corners of the keys.
  5. Allow the oil to soak into the rubber for a few minutes.

Step 4: Wipe off Excess Oil

After allowing the oil to penetrate the rubber, take a clean lint-free cloth and gently wipe off any excess oil. This step helps prevent a sticky residue and ensures a smooth and comfortable touch while using the keypad.

Step 5: Let it Dry

Give the keypad ample time to dry after wiping off the excess oil. It’s essential to wait until the oil is fully absorbed by the rubber. This can take anywhere from 15 to 30 minutes, depending on environmental conditions.
