SILITEC Clean Plus© is a high-energy, low-temperature plasma surface coating.
This amorphous silicon coating, transparent or semi-transparent, provides abrasion, scratch, and corrosion resistance, with ultra-low surface tension, which significantly limits limescale deposits and other suspended particles, making surfaces easier to clean.
Unlike transparent paints or similar coatings, SILITEC Clean Plus maintains the natural appearance of objects while its hydrophobic properties prevent substances from evaporating too quickly, reducing sediment build-up.
Deposition method
SILITEC Clean Plus is obtained through plasma enhanced (or assisted) chemical vapor deposition (PECVD or PACVD), with process temperatures that remain slightly above room temperature.
Objects are placed on specially designed supports and inserted into a vacuum chamber (at 10⁻³ mbar pressure), then saturated with gases, including silyl ethers and oxygen, which are ionized in a plasma state to form a homogeneous coating that can also penetrate undercuts and cavities.
The SILITEC Clean Plus film bonds to the substrate through double bonds (for metals) or plasma grafting (for polymers). This ensures exceptional adhesion, making it impossible for a properly applied silicon oxide coating to peel or degrade over time.
As a result, objects become protected by a homogeneous layer of amorphous quartz, firmly bonded to the substrate, while also enhancing cleaning and maintenance and preventing scratches and abrasion.
Key features of SILITEC Clean Plus©
- BIOCOMPATIBLE & NON-TOXIC SILITEC Clean Plus is biocompatible and completely non-toxic. It is also bacteriostatic, meaning it prevents bacterial growth.
- PREVENTS METAL ALLERGIES: SILITEC Clean Plus can be applied to high-nickel alloys, allowing sensitive individuals to wear watches and jewelry without allergic reactions.
- ULTRA-LOW SURFACE TENSION: The coating prevents limescale deposits and other residues from adhering to the surface.
- STRONG SCRATCH & WEAR RESISTANCE: The coating protects against scratches, abrasion, corrosion, and oxidation.
- HYDROPHOBIC PROPERTIES: SILITEC Clean Plus repels liquids, preventing sediment formation and buildup.
