Multifkunktionelle Hybridschicht MHS-4
The coating of polymeric multi-funktional hybrid layers on surfaces, e.g. metals, glass and plastic, leads to enhanced
materials, since beneficial properties are transfered. Using homogeneous and smooth coatings, enhanced temperature stability,
reduced aberasion, increased pressure stableness and passivation of the material's surface can be achieved.
 Three functions, one material, one coating! |
Application:
 | Wet-chemical production method: unproblematic up-scaling possible, no special equipment necessary. |
| Facile dip-coating, spraying and paint-coating out of solution. |
| Reduced cost for coatings compared to common plasma- ,PVD- or CVD- methods |
| Coatings serve multiple functions: e.g. passivation, pressure stabilization, lubrification, corrosion protection. |
| Thickness of the coating is controlled by concentration of the solution. It is fully adjustable between 5 to 10 mycrometers. |
| Wet application allows coating of difficult-to-reach surfaces in machine parts. Holes and hollow spheres can be protected. |
 Coated metal surface. Rainbow colors indicate the presence of a smooth, nearly transparent coating. |
Technical properties:
| High thermal stability: -240°C to +370°C! |
| High thermal durability and stiffness (up to 600°C). |
| Beneficial gliding and aberasion properties. |
| Excellent elektrical isolation: surface resistivity larger 1016 Ohms. |
| High flame rejection and radiation stability. |
Mechanical properties:
| No phase transitions observed. |
| Non melting material. High glass transition point. |
| Enhanced tension stability: greater 90N/mm2. E-module: 3200N/mm2 (linear with decreasing temperature). |
| High stability to shearing: greater 85N/mm2. |
| Low aberasion coefficient: 0.30 (without additional lubricant). |
