SurTec 650 chromitAL® is a RoHS and WEEE compliant trivalent process. Widely used in the electronics industry due to low surface resistance, and in the aerospace industry due to high corrosion protection on unlacquered surfaces, SurTec combines increased corrosion resistance with preservation of electrical conductivity.

SurTec 650 chromitAL® is used for alloyed and casted aluminium, and pre-treatment before lacquering, gluing and powder coating. SurTec is easy to handle and leaves a visible iridescent coating which is faintly blue to tan in colour.

Benefits of SurTec 650 chromitAL®:

  • Electrical conductivity
  • Corrosion resistance
  • A visible coating
  • Cost effective
  • Provides a base for paint that facilitates bonding
  • Low contact resistance
  • Heat resistance up to 100 °C (212 °F) with minimal corrosion resistance loss
