The use of metal-based catalysts allows for the development of adhesives and sealants with improved performance characteristics, such as faster curing times, stronger bonds, and greater resistance to heat and moisture. Some of the most commonly used metal-based catalysts in the creation of adhesives and sealants include tin, titanium, and zinc compounds.
Our products are centered around the use of tin and bismuth compounds. Tin catalysts, such as dibutyltin dilaurate (DBTDL) and tin octoate, are popular choices due to their effectiveness at promoting crosslinking reactions. They are also known for their fast curing times, selectivity, and ability to work at low temperatures, making them ideal for a range of applications.
Bismuth-based catalysts are known for their low toxicity and biocompatibility, which makes them suitable for use in medical and food packaging applications. They also have a slower curing time compared to tin-based catalysts in polyurethane-based adhesives and sealants, which allows for greater control over the curing of adhesives and sealants.
If you are formulating new polyurethane and silicone-based adhesives and sealants, we have a wide range of specialty chemical metal catalysts to consider. Please refer to the product list or contact us for more information about your specific application and one of our chemists can recommend the catalyst or catalysts for you.
