Before the concave lens sample was cleaned, it was covered with asphalt and dried. (The customer intentionally coated thick asphalt for testing)

Place in SynGC05, heat to 70~80°C and soak for 30 minutes.

Put it in SynGC05, heat it to 70~80°C and soak for 30 minutes, the asphalt on the lens surface has softened and lost its adhesiveness, and it will fall off when touched lightly. At this time, if it is cleaned with ultrasonic vibration, it can be cleaned effectively.

It can also be wiped with a dust-free cloth, which can also wipe the asphalt on the surface.

Suggestions and discussions:

5.1 SynGC05 confirms that the concave lens sample provided by CF can effectively remove the asphalt glue coated on its surface.
5.2 It is recommended to use ultrasonic vibration cleaning to avoid scratches caused by wiping.
5.3 SynGC05 is oily and slightly soluble in water, so it should be cleaned after removing the glue. It is recommended to use our company's dust cleaning agent PTC05 (alkaline, pH>13) to clean, which can remove various organic residues attached to the surface. Thoroughly clean.
