Pfas-free low friction coatings for metallic cutting edges

Overview

The Liquid Entrenched Smooth Surface (LESS) is an innovative coating technology that provides an ultra-low-friction, PFAS-free solution for metallic cutting edges. Developed by spotLESS Materials, Inc., LESS offers a molecularly smooth, slippery barrier that excels in liquid-repellency and anti-biofouling, while remaining optically clear. It creates a non-stick surface without relying on fluorinated chemicals or fragile micro-textures, making it environmentally friendly and robust. This technology is particularly beneficial for industries requiring low friction surfaces on metallic cutting tools, enhancing performance and longevity.

Technical specifications

Key features:

• PFAS-free formulation: Ensures environmental safety and compliance with sustainability standards.
• Liquid-infused polymer brush: Provides a defect-free, mobile low-energy interface.
• Scalable application methods: Can be applied using spray coating, dip coating, and slot-die application.
• Versatile substrate application: Bonds effectively to metals, glass, and polymers with a controlled thickness of ~500 nm or less.
• Durability and performance: Exhibits excellent liquid-repellency and anti-biofouling characteristics, reducing sliding friction across various contaminants.

Technology readiness level

The technology is currently at Technology Readiness Level 3, indicating it is in the active stage of research and development with laboratory validation underway. Several partnerships are engaged in scale-up evaluations to prepare for broader market applications.
