STC2200 series of strengthening liquid instructions

Product Introduction:

Mainly composed of silicone resin and alcohol solvent, used for polycarbonate (PC), because the refractive index of the cured coating is close to that of PC, no rainbow will be generated after the surface of PC is strengthened.

Advantage Features:

refractive index of the cured coating, andThe refractive index of PC is close to that of PC surface without rainbow.

Application areas:

for polycarbonate (PC) surface strengthening.
