arceram ULTRA
Ceramic Coating Detection Spray
arceram ULTRA Test – How to Identify a Ceramic Coating on Surfaces
A high-quality ceramic coating differs fundamentally from conventional waxes or polymers. It forms a strong chemical bond with the clear coat. Since this invisible protective layer cannot be seen with the naked eye, targeted testing with arceram ULTRA from arcotest GmbH helps identify its presence.
Application: Spray arceram ULTRA onto the cleaned surface approximately 3–4 times. If the ceramic coating is intact, the spray droplets immediately contract into tall, almost spherical beads. On conventional, uncoated paintwork, arceram ULTRA remains spread out, wetting the surface over a larger area.
Application note: As surfaces can vary considerably, a suitability test should be carried out before each application.
Cleaning: After testing, wipe arceram ULTRA off the surface with a damp cloth.

arcospray® 38
The arcospray® 38 test ink is a test liquid with a surface tension of 38 mN/m. It has been designed to quickly detect whether the surface is grease-free, as values equal or greater than that mean freedom from grease. After its application, arcospray® 38 can be removed without residue using oil-free clean blower air (compressed air). Not only large areas, but also very small areas, such as chain links, can be assessed quickly and easily by the arcospray® 38.
38 mN/m • 38 dyn/cm with accuracy +/- 1.0 mN/m Available in spray bottles 3,4 fl oz / 100 ml
- ideal for very small and large surfaces
- simple handling
- Non-toxic
- Not harmful to the environment
- Not harmful to health
- residue-free testing of surfaces
- Easy spraying of the arcospray ink
- Result visible within 2 seconds
- Non-contact surface testing
Service
Expert advice, guarantee of the given values, reliable and prompt delivery, cooperation with our customers at home and abroad have been our absolute priority for 49 years.
Quality control
For quality assurance, the inks are tested using a state-of-the-art contact angle measuring device, taking temperature and density into account. Safety data sheets provide information on handling, storage and transport regulations.
