How Thermal-Cure Coatings Work

Processes refined for
precision, quality, and scalability

Surmodics ST supports multiple coating applications and curing processes to meet the needs of diverse device designs, manufacturing environments, and commercial requirements.

Advantages of Thermal-Cure Systems

Engineered for precision, consistency, and clinical reliability

Predictable lubricity profiles

Smooth advancement through tortuous pathways and tight device interfaces.

Thin and uniform coating layers

Supports tight tolerances and consistent system-level interaction.

Coating Durability under stress

Maintains coating integrity during bending, flexing, and repeated motion.

Lowest Particulate Counts

Our coatings boast the lowest particulate counts in the industry.

Versatile substrate compatibility

Validated for Pebax, nylon, polyurethane, PEEK, HDPE, LDPE, stainless steel, Nitinol, silicone, and blended polymers.

Manufacturing-friendly processing

Formulated to integrate easily into lean production workflows and quality systems.

When Thermal Coatings Are the Right Choice

Our team evaluates device geometry, material selection, and performance requirements to determine whether thermal-cure, or a UV-cure, offers the best outcome. Thermal-cure systems are recommended for device areas that demand performance under load, such as:

icon

Strong and consistent coating adhesion

icon

Smooth shaft-to-shaft passage

icon

Controlled friction across repeated cycles

icon

Durable coating behavior during mechanical stress

icon

Reliable performance across polymer and metal substrates
