Chemical resistant coating for silicone keyboard

Chemical resistant coating for silicone keyboard

Chemical resistant coating for silicone keyboard

(OP)
Hi,

I have tried PU coating, but the solvent resistance of this coating was really poor. The coating start peeling after several sprays by MEK. And one supplier recommend the epoxy resin coating, but I don't think this kind of coating does resist to the Ketone as well. And normally the keyboard coating should be able to have good stain and abrasion resistance.

Does anyone know any coating can be used on silicon keyboard with good chemical resistance?

All comments welcome!

Regards

Tang
