Two, with silicone resin as ink binder, liquid acid
Anhydride as a curing agent, after thermal curing can be higher heat resistance
The printed film. But as a pad printing ink its adhesion and pad printing
Energy is a very important factor in the molecular design of the binder
In addition, by adjusting silicone resin and ink additives and matching
To make the kinematic viscosity of A and B reach A certain level respectively
When the mass ratio of each component is 1/4,
Ink pad printing time can reach more than 100 degrees. In addition, the
After the components are stored for 6 months, their viscosity, pad printing performance
And so on basically unchanged. It shows that the silicone resin has better stability
All right.
Three, in the test to add silicone resin and two - component ink
Heat resistance, weather resistance, solvent resistance and electricity resistance of pad printing film
Insulation properties visible silicone resin two - component thermosetting ink
Adhesion up to grade 2, heat, cold, gasoline, kerosene
The performance and electrical insulation performance is good, so the ink can be used
Special ink for pad or screen printing.
