REDIVERS 300 Promotor 9700 is a „Crosslinker”, which is added to water based printing inks, in order to achieve excellent properties in the final print.
REDIVERS 300 Promotor 9700 react with Carboxy- and Hydroxy-groups in the dried print. After 3-4 days storage at room temperature the print should be fully cured.
The Promotor will hydrolyze slowly in water based inks, therefore it is only fully active for 6–8 hours. We recommend that extra promotor is added after 6 hours.
