Medical device coatings are an integral part of medical device development. These coatings may have antibacterial, antithrombotic, drug-eluting or hydrophilic properties, and can be customized to specific clinical needs during medical device development. However, ensuring that these coatings are evenly applied and function as intended is a complex and critical process. Medical device coating coverage testing services are fundamental to this process, providing a comprehensive evaluation method to ensure that coatings on medical devices meet strict quality and performance standards.
