Tin Catalyst for Polyurethane

Borchers® LH 10 is a tin catalyst for water-based two-component polyurethane systems. Borchi® Kat 28 works well in solvent-based systems.

 

Benefits of Tin Catalysts for Polyurethane

Borchers® LH 10 accelerates the cross-linking process and improves the drying of chemically curing systems. It enhances scratch resistance, hardness, and mechanical persistence. This tin catalyst for polyurethane is a 10% aqueous emulsion of an organic metal compound (DBTL).

 

Applications

Ideal applications include aqueous two-component polyurethane and high gloss coatings.

  • Applications

    • Coatings
      • Aqueous two-component polyurethane
      • High gloss

  • Dosage

    Borchers® LH 10 has to be added to the grinding process of the base component. The recommended amount should be
    around 0.4 – 0.6 % regarding solid content of the binder. The precise dosage should be determined beforehand in trials.

  • Storage

    Protect from the effects of weathering and store at temperatures between 5 and 30 °C. Once opened, containers should be
    resealed immediately after each removal of the product. It has to be protected against frost.

  • Safety
