Replacing Tin-based Catalysts without Compromising Performance in Polyurethane Coatings

Due to their durability, polyurethane coatings are important technologies in the industrial coatings market. For many years, tin-based catalysts such as dibutyltin dilaurate (DBTDL) were commonly used as crosslinkers in polyurethane reactions. Crosslinking adds benefits such as faster dry times, increased hardness, durability, abrasion resistance, and water and solvent resistance. However, a catalyst can negatively impact performance properties such as pot life. Following market trends and regulatory pressures, this presentation will address how Borchers’ catalyst technology can help replace tin-based catalysts without compromising performance. The data will also highlight how performance issues such as short pot life can be resolved.
