Silicone nano-brushes as a permanent anti-adhesion coating for EPDM rubber
Introducing silicone nano-brushes, a permanent anti-adhesion coating for EPDM rubber, significantly reducing adhesion of solid substances and enhancing durability during repeated molding processes.
Overview
Silicone nano-brushes present an innovative solution as a permanent anti-adhesion coating for EPDM rubber. This advanced coating technology effectively repels a wide range of liquids and reduces the adhesion of solid fouling substances like ice and adhesives. The covalent attachment of the silicone nano-brushes ensures that the coating is highly durable, maintaining its effectiveness through repeated EPDM molding and de-molding processes. This makes it an ideal solution for industries that require long-lasting materials resistant to fouling and adhesion.
Technical specifications
Key features:
- Liquid and solid repellency: The silicone nano-brushes repel both high and low surface tension liquids, such as oils and solvents, and substantially reduce the adhesion of solid foulants.
- Durability: The covalent bond to the substrate ensures the coating remains effective through repeated use.
- Performance: Demonstrates a 100–1000 times reduction in the force necessary to remove solidified foulants.
Applications:
- EPDM rubber moldings
- Industrial applications requiring anti-adhesion properties
- Situations involving repeated exposure to adhesives and solid foulants
Technology readiness level
The silicone nano-brush technology is currently at TRL 4, indicating that it has been validated in a laboratory environment. The next steps involve further testing to confirm adhesion reduction across various conditions and substrates, ensuring its readiness for broader industrial applications.
