Cat & Pelapis (Coating)

Paints and coatings serve dual purposes: functional protection and aesthetic enhancement. In automotive, coatings protect against corrosion and UV degradation while delivering a flawless finish. In aerospace, coatings must withstand extreme conditions while maintaining adhesion to lightweight composites. In packaging, coatings ensure print quality and barrier properties.
The science behind coatings revolves around surface interactions. For a coating to adhere properly, it must wet the substrate effectively. Wettability is influenced by the surface energy of the substrate and the surface tension of the coating formulation. If the coating fails to wet, defects such as peeling, blistering, or poor coverage occur.
DataPhysics Instruments address these challenges with precision. The OCA series measures static and dynamic contact angles, providing insights into how coatings spread and adhere. The DCAT tensiometer evaluates surface and interfacial tension, crucial for understanding paint-substrate compatibility. The HGC humidity generator simulates environmental conditions, allowing coatings to be tested under controlled humidity to predict real-world performance.
Surface preparation is equally important. Substrates may undergo plasma treatment, chemical cleaning, or mechanical abrasion to increase surface energy. DataPhysics devices quantify the effectiveness of these treatments by comparing contact angle and surface energy values before and after.
In R&D, these tools help optimize formulations by balancing viscosity, flow, and curing properties. They also support quality assurance by providing reproducible, automated measurements that can be integrated into production workflows. This reduces variability, enhances reliability, and ensures compliance with industry standards.
Ultimately, paints & coatings are more than just decorative layers—they are engineered systems whose success depends on precise control of surface and interfacial properties. DataPhysics Instruments empower manufacturers to achieve this control, driving innovation and quality across industries.
