NB72 Catalyst is a chemical cross-linker which may be added to certain Nazdar screen inks for improved adhesion on various substrates. The addition of NB72 can cause yellowing of the ink film on exposure to sunlight. For applications requiring outdoor exposure, use NB80 Adhesion Promoter in place of NB72.
Adhesion should always be tested as adhesion depends upon curing conditions, age and manufacturer of the substrate. Adhesion may be improved when the substrate is cleaned with a suitable solvent such as isopropanol.
