Paint Maker ADAS Radar Optimized Color Resources: AkzoNobel

Posted on 26 July 2024 | Share: | Print Print

Changes in advanced driver assistance systems (ADAS) radar technology are introducing new refinishing considerations. Paint film thickness not only may affect the performance of ADAS radars, color formula selection may also be a contributing factor. What resources do repairers have available? Let’s see what AkzoNobel has to offer.

AkzoNobel has a Color Tinting And Blending Considerations For Vehicles Equipped With ADAS Technology technical service bulletin (TSB). This TSB has general information and considerations pertaining to radar optimized color formulas. AkzoNobel, when requested by an OEM, redevelops color formulas and test them to ensure radar functionality with proper repair methods.

Per the TSB:

  • "Always strictly follow the OEM procedures provided for radar equipped vehicles as well as any specific instructions or color formulas provided by the paint manufacturer. Repair methods differ from OEM to OEM and may even vary between models from the same manufacturer."
  • "This Technical Service Bulletin (TSB) provides general information regarding color tinting and blending when performing repairs that include interaction with a radar transmission zone."

AkzoNobel provides color formula and color blending considerations for refinishing. Per Color Formula Considerations:

  • "When identified, the radar transparent color formula must be used when painting in radar zones.
  • Radar transparent color formulas must be mixed accurately and without deviation.
  • Radar transparent color formulas must not be manually tinted, adjusted, or digitally optimized.
  • Not every OEM requires radar transparent formulas - always refer to the OEM repair manuals."

Found in the Color Blending Considerations area, AkzoNobel states:

"Blending the basecoat color within the radar zone is not allowed. Within the radar transmission area, the refinish layers must be smooth and uniform."

When a radar optimized color is to be used, AkzoNobel recommends the following considerations:

  • "Always create sprayout panels to understand if there is a color issue before painting the vehicle
  • Use spray gun application technique (pressure, distance, orientation) to control the color
  • Blending panels adjacent to radar transmission zone may be necessary when using the currently available radar transparent formulas"

Improper color selection and application may cause ADAS to malfunction and potentially fail. Check OEM repair information to identify what restrictions may apply to the repairs you are considering. Always verify that the ADAS is functioning properly after completing repairs.
