Adhesion: 2 MPa — securely bonds to the substrate, preventing peeling and delamination.

Summary: Floor peeling and large-scale detachment often stem from insufficient paint film adhesion. CS-2000 floor stain passed the pull-off test conducted by the Guangzhou Aging Institute.Adhesion: 2 MPa (range 1.2~1.9 MPa), 100% cohesive failure in BThe coating bonds firmly to the substrate, reducing the risk of peeling and delamination.

Floor peeling and delamination: a frequent rework pain point in construction projects.

Many colored flooring projects look perfect upon completion but develop issues after a period of use: surface blistering, peeling at edges and corners. In severe cases, large sections of the coating tear off, causing the color layer to fail completely.

Common causes of peeling: 👉 Delamination at the coating-substrate interface (adhesive failure), indicating insufficient adhesion; even minor stress can cause the entire film to peel off. 👉 Moisture and oil penetrate through micro-cracks beneath the coating, worsening delamination. 👉 Large-scale peeling requires complete removal and reapplication, causing production downtime and high repair costs.

Many people often confuse:Adhesion is not the same as hardness.High hardness doesn't guarantee strong adhesion. Hardness measures a paint film's resistance to scratching, while adhesion reflects the bond strength between the film and the substrate. In testing, Grade B (cohesive failure) indicates that failure occurred within the paint film itself, not at the interface with the substrate. This means the adhesive strength between the film and the substrate exceeds the film's internal strength—a highly ideal outcome.

Adhesion Industry Benchmark & Competitive Comparison

Test standard GB/T 5210‑2006, pull-off adhesion test.

<1.0MPa: Standard colored surface, prone to delamination and peeling; suitable only for light-duty indoor environments.
1.0–1.5MPa: Typical market range for standard epoxy pigmented paints and floor coloring products; some may cause interface damage, with delamination risks under heavy-duty conditions.
1.5‑2.5MPa: Mid-to-high-end industrial flooring tier (CS-2000 measured 2 MPa; 100% cohesive failure in B falls within this range)Strong adhesion; failure occurs within the coating itself, not at the substrate interface. ‑ ≥3.0MPa: High-performance specialty system requiring strict substrate and construction conditions; higher cost.

Competitive Comparison: Most standard floor coloring and epoxy paints on the market show pull-off adhesion concentrated between 1.0‑1.5MPa, with frequent interfacial delamination. CS-2000 achieves 2 MPa, with 100% cohesive failure within B.Superior bonding performance compared to standard colored floor finishes on the market.。

In simple terms: When peeling off the coating, it should break internally rather than detach cleanly from the substrate. This indicates that the colored layer is firmly anchored to the base and resists large-scale peeling or flaking.
