Adhesion promoter for silver mirror inks

121K Additive for anti-coming-off of aluminum powder is a kind of special use additive resin with wide compatibility. To enhance the initial and long term adhesion of different binder to metal, inorganic, and plastic, and solve the problem of inner layer adhesion in the coating. Also prevent the coming- off of al-powder in the plastic al-powder coating and improve the flexibility of coating film.

Mixed with other binder and different paint system to enhance the adhesion of ink to glass and plastic substrate.

Improve the adhesion of printing in on the different substrates. Used in the aluminum powder coating, to prevent coming-off and floating of aluminum powder. Not causing coarsening and darkness of aluminum powder, keep the storage stable.
