CD Ceramic Nano-Coating Application 2

Question 1

What is the primary chemical component that gives ceramic coatings their hardness and hydrophobic properties?

Accepted Answer

Silicon dioxide (SiO2)

Answer

Silicon dioxide (SiO2) is the core ingredient in most ceramic coatings, forming a glass-like layer that provides hardness and water-repelling properties.

Question 2

After applying ceramic coating in a cross-hatch pattern, you notice high spots forming. What is the correct immediate action?

Accepted Answer

Wipe off with a clean microfiber before the coating flashes

Answer

High spots must be leveled with a clean microfiber leveling cloth before the coating flashes (begins to cure), as removal becomes very difficult once cured.

Question 3

Which environmental condition most negatively impacts the initial cure of a ceramic nano-coating?

Accepted Answer

Humidity above 70%

Answer

High humidity above 70% can cause ceramic coatings to cure too quickly or unevenly, leading to streaking, high spots, and poor bonding.

Question 4

A client's vehicle has previously applied wax. Before ceramic coating, the detailer must remove the wax because:

Accepted Answer

Wax increases surface tension, preventing nano-bonding

Answer

Wax creates a barrier that increases surface tension and prevents the ceramic coating's SiO2 molecules from bonding directly to the clear coat.

Question 5

What does a contact angle measurement above 100° indicate about a cured ceramic coating?

Accepted Answer

The coating exhibits strong hydrophobic properties

Answer

A contact angle above 100° indicates excellent hydrophobicity, meaning water beads tightly and rolls off the surface easily.
