Types of colours

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)
