We aim for quality and excellence.
Our laboratory ensures the quality, consistency, and durability of CED coating. Since CED coating is widely used in automotive and industrial applications, laboratory testing helps maintain strict quality control by monitoring coating thickness, adhesion, corrosion resistance, and chemical balance. Regular bath parameter checks (pH, conductivity, non-volatile content) ensure the coating process remains stable, preventing defects such as uneven deposition, poor adhesion, or corrosion failure. Cyclic corrosion and salt spray testing (ASTM B117, ASTM D1654) are particularly important, as they simulate harsh environmental conditions, including exposure to moisture, temperature variations, and road salt, which are common in real-world applications. These tests help assess the long-term corrosion resistance of CED coatings, ensuring that coated parts can withstand extended service life without premature rusting or surface degradation. By implementing ASTM and OEM standards, a laboratory ensures that CED-coated components meet industry requirements, enhancing both product lifespan and customer satisfaction
