Borchi® Kat 2115

Next generation tin-free catalyst for one- and two-component polyurethane systems and RTV silicones

Physical Characteristics

Metal content Bi, Zn
Viscosity Max. 1000 mPa·s (20°C, ISO 3219 (A))
Density 1.055 – 1.095 g/cm³ (20 °C, DIN 51757)

Features

    • Neodecanoate mixed metals that can be used to replace DBTDL, DOTL, and amine-based catalysts

     

    • Extended pot-life and higher hardness compared to DBTDL and leading bismuth catalysts

    longer pot life with tin free catalyst

    better hardness with tin free catalyst

     

    • 2-ethylhexanoate-free (2-EH) for improved labeling over traditional bismuth octoate

     

    • Additional Benefits:
      • Maintain outstanding corrosion resistance
      • No impact on achieving high gloss finishes
      • Will not contribute to yellowing
      • Comparable dry times to tin-free bismuth technology

     

    fast dry times with DBTDL replacement catalyst

     

Applications

  • Solvent-based and solvent-free pigmented and clear one- and two-component polyurethane coatings
    • Automotive Refinish
    • General Industrial
    • Coil
  • Suitable for polyurethane foams

Dosage

The recommended addition rate of Borchi® Kat 2115 in polyurethane coatings is, according to our experience, between 0.02 and 0.15% product, calculated on solid binder. The exact amount depends on the used binder and should be determined by means of preliminary trials. Borchi® Kat 2115 can be added either in the supply form or diluted (e.g., in butyl acetate) to the polyol component of the coating system. Borchi® Kat 2115 should not be diluted below 10% of the supply form, since those solutions are only stable for a limited period of time.

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.
