Sikkens Scratch Test

Sikkens Coating Scratch for Corrosion Test

Sikkens Scratch Tester CC3000

For cutting the panel prior to the corrosion test

The NK Sikkens CC3000 Scratcher is a precision cutting tool designed to make incisions in coated panels or test specimens, in accordance with the requirements of salt spray chamber corrosion testing. Its tilting head design and ergonomic handle allow for uniform cuts down to the substrate with minimal effort and high repeatability, ensuring that the cut reaches the metal substrate without damaging it.

Compatible with three interchangeable blade widths (0.5 mm, 1 mm and 2 mm), the NK-CC3000 meets the specifications of Daimler Chrysler, the original Sikkens version and the 2018 update to ISO 12944-6, respectively.

Application

  • Salt spray testing: preparation of test specimens for corrosion chambers in accordance with ISO 9227 / DIN ISO 9227.
  • Evaluation of paint systems: verification of corrosion resistance in accordance with ISO 12944-6:2018 for steel structures.
  • Automotive specifications: 0.5 mm blade scratch tests in accordance with Daimler Chrysler and equivalent OEM specifications.
  • Quality control of coatings: industrial paint, galvanising and surface treatment laboratories.
  • Accreditation and certification: laboratories requiring reproducibility in the preparation of the test incision.

Features

  • Tilting head that compensates for hand movement, ensuring a uniform cut at a constant depth.
  • Integrated blade support that facilitates positioning and guiding the cut across the panel.
  • Ergonomic, low-effort handle that reduces operator fatigue during repetitive testing.
  • Three interchangeable blades: 0.5 mm (Daimler Chrysler), 1 mm (original Sikkens) and 2 mm (ISO 12944-6:2018).
  • Replacement blades available individually to extend the service life of the equipment.
  • Complies with ISO 17872 (marking procedure for coatings for corrosion testing).

FAQS

Depending on the type of coating, the test can reveal surface scratches, permanent deformation, cracks, loss of adhesion between layers or even exposure of the substrate.

The Persoz and König methods analyse the hardness and degree of curing of the film, whilst the scratch tester allows the coating’s resistance to mechanical damage caused by contact or localised abrasion to be assessed directly.

Because these surfaces are exposed daily to contact, scuffing and frequent cleaning. A coating with high scratch resistance retains its aesthetic appearance and protective properties for longer.
