PLUS VLH
The evolution of PLUS® VL with improved performance
PLUS® VLh is a clear water-based topcoat. It can be applied to GEOMET® 321 coating and has similar parameters to PLUS®VL. It has been developed to radically improve the friction performance for cases of difficult tightening (i.e.with aluminium or catophoretic paint) and complies with new automotive industry expectations (i.e. VW 01131-1/2).
Characteristics and performance*
- Friction coefficient on GEOMET® 321 base-coat grade A (>24g/m²)
PLUS® VLh : µtot = 0,09 - 0,14
- Salt Spray Test according to ISO 9227 / ASTM B117
GEOMET® 321 + PLUS® VLh > 720 hours without red rust
- Coating weight of PLUS VLh: 5 g/m2 minimum
- Same IMDS as for PLUS® VL
- No induced hydrogen embrittlement
- Improvement of friction performance on and in aluminium (double tightening within elastic limit on aluminium according to VW 01131-1)
- Improvement of friction performance regarding multitightening (5x) onto catophoretic paint while avoiding stick-slip problems for cases of difficult tightening
- Excellent behaviour in tests of loosening at high temperatures (VDA 235/203 ; VW 01131-2)
- Excellent resistance to solvents, fuels and brake fluids (VDA 621-412)
* Results may vary depending on substrate, geometry of parts and type of application processes. The tribological properties (COF, stick-slip…) are validated on a reference hex-headed M10x55 screw according to ISO 16047.
Application process
These water-based inorganic products can be applied in one single thin coat by Dip-Spin or spray, using bulk or rack coating process.
