Catalyst 806 is a high reactive tertiary amine and well suited to cure polyurethane formulations based on Askocoat technology. Catalyst 806 has a high flash point, shows low volatility and therefore, ATEX-equipment can be avoided in most cases. Catalyst 806 is applied as fine spray into the coating drum onto the uncured Askocoat-polyurethane layer of the fertilizer granules. Curing of the Askocoat-layer occurs within seconds. Catalyst 806 has functional end-groups that irreversibly react into the polyurethane coating.
