Advanced PVD coatings to prevent PIR foam adhesion

Overview

Advanced Physical Vapor Deposition (PVD) coatings are being explored to address adhesion issues in the manufacturing of polyisocyanurate (PIR) foam. These coatings, including titanium nitride (TiN), chromium nitride (CrN), titanium carbonitride (TiCN), and diamond-like carbon (DLC), are designed to provide non-stick properties, low surface energy, and strong chemical resistance. By reducing the adhesion of PIR foam to molds and tools, these coatings aim to enhance manufacturing efficiency, lower maintenance needs, and prolong the service life of equipment, all while preserving the quality of the produced foam.

Technical specifications

• Non-stick properties: PVD coatings provide excellent non-stick surfaces to prevent foam adhesion.
• Low surface energy: These coatings have low surface energy, minimizing reactive material buildup.
• Chemical resistance: High resistance to chemical interactions ensures coating durability.
• Thermal stability: Suitable for high-temperature applications, maintaining effectiveness under production conditions.
• Materials: Titanium nitride, chromium nitride, titanium carbonitride, and diamond-like carbon.
• Application methods: Magnetron sputtering or cathodic arc deposition techniques are used to apply these coatings.

Technology readiness level

Currently, this technology is at TRL 3, where experimental proof of concept has been established. Further development includes optimizing deposition parameters, characterizing coatings, and simulating manufacturing conditions to evaluate adhesion reduction and overall performance.
