CATALYST 704
Catalyst 704 is a relatively volatile tertiary amine and well-suited to cure polyurethane formulations based on Askocoat technology. Dehydrated air as well as nitrogen are suitable carrier gases. The gas stream takes up the catalyst which is then applied into the coating drum onto the uncured Askocoat-polyurethane layer of the fertilizer granules. Curing of the Askocoat-layer occurs within seconds.
