Nano-Scale Liquid Glass Coatings

7656 Plastic-Metal Premium

7656 Plastic-Metal Premium is a high-performance SiO₂-based nano-scale coating designed for plastics, metals, and painted surfaces. It provides an invisible yet durable protective barrier that reduces the adhesion of contaminants, making surfaces easier to clean and maintaining their optimum appearance for longer.

Key Features

  • Clear, colorless liquid, virtually undetectable after application; surfaces may appear slightly brighter
  • Coating Thickness: 100-150 nm (invisible to the human eye)
  • Strong hydrophobicity and oleophobicity, reducing the adhesion of dirt, lime, and environmental contaminants
  • Quick and simple 'do-it-yourself' application process
  • Contaminants such as grease, oil, and lime scale do not easily adhere, enhancing the 'easy-to-clean' effect
  • Permanent ionic bond with the substrate, ensuring long-lasting durability and excellent resistance to abrasion
  • Resistant to temperatures up to 250°C, as well as frost and UV exposure
  • Compatible with most household and industrial cleaners (except concentrated alkali)
  • Breathable surface
  • Inert and food-safe, suitable for food-related applications
  • Biostatic properties reduce microbial growth, contributing to improved hygiene
  • Complies with the latest European Union Regulation (EU) 2024/2462 which specifies limits of less than 25 ppb for PFHxA and less than 1000 ppb for total fluorine content)

Key Benefits

  • Surfaces stay cleaner for longer, reducing cleaning time and effort
  • Non-stick surface eliminates the need for abrasive scrubbing or harsh chemicals
  • Provides 3-10 years of protection depending on the environment, reducing the need for frequent reapplications
  • Reduced cleaning frequencies save energy, time, and cleaning costs
  • UV stability protects surfaces from sunlight and harsh chemicals
