Alpaste® for water-based coating

Outline

Gentle on the environment

Untreated aluminium paste readily reacts with water and it cannot be used as it is in water-based coatings. To solve this problem, as aluminium pastes for water-based coating, we offer the WXM Series and WL Series, which have excellent cost performance, and the Emeral Series (EMR), which has a silica coating for excellent gas suppression performance, so that there is almost no gas emission.

Features

  • ・WXM Series
    The surface of the aluminium in this series of products has been water (anticorrosion) treated with phosphorous-based compounds.
    The series has excellent cost performance.
  • ・WL Series
    The surface of the aluminium in this series of products has been water (anticorrosion) treated with molybdenum-based compounds.
    The series has excellent cost performance.
  • ・EMR Series
    The surface of the aluminium in this series of products has been coated with high-density silica. The very fine silica film prevents the emission of hydrogen gas.
