Advanced Paint Adhesion Cross‑Cut Analysis Kit QPI‑CC2800 – ASTM D3359 Standard:

The Advanced Paint Adhesion Cross‑Cut Analysis Kit QPI‑CC2800 is a precision instrument designed for evaluating coating adhesion through standardized cross‑cut testing. It integrates digital imaging technology and automated analysis software to deliver accurate, repeatable, and traceable results that comply with ASTM D3359 and ISO 2409 test methods.

ASTM Test Method — Adhesion by Cross‑Cut (ASTM D3359)

The ASTM D3359 standard defines a procedure for assessing the adhesion of coatings to metallic substrates using a cross‑cut pattern. The QPI‑CC2800 automates this process through camera‑based image recognition and digital analysis.

Procedure Summary

1. Surface Preparation The coated specimen is cleaned and conditioned according to ASTM D3359 guidelines. The cross‑cut tool of the QPI‑CC2800 creates a precise grid pattern of parallel incisions through the coating film to the substrate.

2. Cross‑Cut Formation The instrument ensures uniform spacing and depth of cuts, typically forming a 6 × 6 or 11 × 11 grid depending on coating thickness. The precision cutting mechanism maintains consistent geometry, eliminating operator variability.

3. Flaking Evaluation Traditionally, the flaked area is judged visually. The QPI‑CC2800 replaces this manual step with camera‑driven digital analysis, capturing high‑resolution images of the cross‑cut area under controlled LED illumination.

4. Digital Image Processing The system’s software identifies flaked regions, calculates the percentage of detached coating, and assigns the corresponding ASTM adhesion classification (from 5A to 0A). This automated process ensures objective, repeatable results.

5. Reporting The instrument generates a digital report including refractive index, flaking percentage, classification, and image documentation for traceability and quality assurance.

Engineering Purpose

The ASTM method provides a standardized way to quantify coating adhesion strength. By integrating digital imaging, the QPI‑CC2800 enhances precision, minimizes human error, and supports laboratory and production‑line quality control.

ISO Test Method — Paints and Varnishes Cross‑Cut (ISO 2409)

The ISO 2409 standard specifies a similar procedure for evaluating coating adhesion using a cross‑cut pattern, but emphasizes international reproducibility and documentation.

Procedure Summary

1. Grid Cutting The QPI‑CC2800 performs the cross‑cut using a calibrated cutting head that ensures uniform spacing and depth across the test area.

2. Surface Cleaning and Imaging After cutting, the instrument’s integrated camera captures the grid under optimized LED illumination. The software automatically adjusts contrast and exposure to highlight flaked regions.

3. Automated Analysis The system calculates the flaking ratio and assigns an ISO adhesion classification (from 0 to 5). Each result is stored with image data and timestamp for traceability.

4. Repeatability Verification ISO procedures require consistent results across multiple tests. The QPI‑CC2800’s automated imaging ensures identical evaluation conditions, improving reproducibility between operators and laboratories.

Engineering Purpose

The ISO method ensures international comparability of adhesion results. The QPI‑CC2800’s automation aligns perfectly with ISO’s emphasis on precision, documentation, and repeatability.
