Standard colours
Polyester (PES)
- PES – good corrosion resistance, very good adhesion
- PES HD (High Durability) – UV resistance, higher corrosion resistance as well as higher weather condition resistance than PES, greater flexibility
- PES TEXT – texture/structural surface, higher resistance than PES HD
PUR, PUR/PA (polyurethane, polyurethane/polyamide)
- PUR/PA – excellent mechanical damage resistance due to structural surface (polyamide particles), high corrosion and UV-resistance
PVDF (polyvinyl difluoride)
- High UV-resistance, high chemical resistance
- Application for construction elements in environments with higher UV-load or in the industrial environment (chemical resistance)
Non-standard colours
Gravure printing
- PES HD-based sealer imitating for example the appearance of wood
- Possibility of outdoor application, total coat 25 µm
Multiply systems
Three-coat:
- polyester sealers using “clear coat” with total coat thickness of 40–50 µm
- PVdF with “barrier coat” (RAL 5002), PVdF with clear coat (RAL 7002)
Four-coat:
- PVdF with “barrier coat” (RAL 3000, RAL 5026)
