Matrix Engineered Mineral Board

Mineral bound calcium silicate boards.

PROMATECT®-L500 is a lightweight mineral matrix engineered board which is off-white/beige in color and has a smooth sanded surface on one face with a lightly honeycombed texture on the reverse face.

PROMATECT®-L500 is chemically inert and is resistant to diluted acids and alkalis. Boards should be protected where high chemical concentrations are likely to occur.

PROMATECT®-L500 is resistant to the effects of moisture and will not physically deteriorate when used in damp or humid conditions. Performance characteristics are not degraded by age or moisture. Untreated surfaces will absorb water which can cause some loss of strength but strength is regained after drying. PROMATECT®-L500 does not encourage mold growth and is resistant to attack by vermin.

ADVANTAGES

  • Resistant to the effects of moisture
  • Not physically deteriorate when used in damp or humid conditions
  • Performance characteristics are not degraded by age or moisture.

Applications

    • Electrical Cable Enclosures
    • Wall Structures
    • Ventilation & smoke extraction enclosures

PROCESSING & MACHINING

When machining the product with power tools, do not breathe dust and respect the regulatory occupational exposure limits for total inhalable and respirable dust. Wear safety goggles. Avoid contact with skin and eyes. Use dust extraction. In case of insufficient ventilation, wear suitable respiratory equipment to avoid health effects. For more information: request Safety Data Sheet.

WASTE DISPOSAL

Refer to local legislation

If not available: The board is not classified as a dangerous substance and no special provisions are required regarding the carriage and disposal of the product to landfill. They can placed in an on-site skip with other general building waste.
