Best Mercury Replacement Catalyst


Many industrial polyurethane applications require a delay from mixing to the onset of the gel reaction. This allows a period time of in which the system maintains fluidity essential for processing. After that, there should be a sharp gelation profile “snap cure” with or without the assistance of heat. Mercury based compounds provided this long induction period (“Pot Life”) followed by a good snap cure but due to their inherent toxicity replacements were essential.
