Borchers® LH 10

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.

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.
