Paint Adhesion Test Services

Why Paint Adhesion Testing Matters

Paint adhesion testing measures how strongly a coating sticks to its substrate. Poor adhesion causes failures like peeling, blistering, and flaking—issues that degrade appearance, trigger corrosion, shorten service life, and fuel customer complaints. In sectors such as automotive, aerospace, construction, plastics, and consumer goods, one adhesion failure can cascade into warranty costs or recalls. That’s why paint adhesion testing is a vital quality control checkpoint, not just a formality.

Typical Causes of Adhesion Failure

• Inadequate cleaning or degreasing before painting
• Improper primer selection or incompatible coating layers
• High humidity or temperature swings during application or curing
• Surface contamination by oil, dust, or moisture
• Excessive film thickness or curing temperature deviations

At Kiyo R&D Lab, we don’t stop at pass/fail. Our analysts identify why adhesion underperforms and suggest corrective actions—from surface preparation tweaks to curing optimization.

Standards & Methods We Perform

• ASTM D3359 – Cross-Cut Adhesion: Precision cuts and standardized tape removal assess the degree of flaking or detachment on metals and hard substrates.
• ISO 2409 – Cross Hatch: Similar to D3359 with defined spacing and class ratings (0–5) widely used for industrial coatings.
• ASTM D4541 / ISO 4624 – Pull-Off: A bonded loading fixture (dolly) measures the force to detach the coating—ideal for thicker films and specialty substrates.
• ASTM D4060 – Taber Abrasion: Not purely an adhesion test but useful for understanding wear-driven delamination and long-term durability.

All tests are executed using calibrated equipment under controlled conditions for repeatable, traceable results.

Who Uses Our Paint Adhesion Test Services?

• Automotive & Transport: Body panels, plastic trims, under-the-hood components
• Construction Materials: Architectural coatings, ACPs, glass facades, outdoor fixtures
• Electrical & Electronics: Insulative coatings and conformal layers
• Consumer Goods: Appliances, furniture, hardware—appearance and corrosion control
• Defense & Aerospace: High-reliability finishes in harsh environments

Our paint adhesion test services – Kiyo R&D Lab provide not just numbers but insights to improve paint systems and process conditions.

Our Process: From Sample to Certified Report

1. Sample Receipt & Verification: Each sample is logged with traceable IDs and specified standards.
2. Conditioning: Standard humidity/temperature conditioning to eliminate test bias.
3. Method Selection & Testing: We apply the appropriate standard based on substrate, film build, and use-case.
4. Observation & Grading: Visual ratings and/or quantitative pull-off strength with documented failure modes.
5. Reporting: NABL-endorsed certificates with results, photos (where applicable), and recommendations.

Turnaround: Most standard adhesion tests can be reported within 1 working day.
