STC3505 helmet lens special PC strengthening solution
Mainly composed of silicone resin and alcohol solvent, used for polycarbonate (PC); Wear resistance can meet the requirements of European customers, sand falling experiment E/ECE/324 Regulation No.22,Reduced of Abraded Sample Luminance is less than 5; On the premise of ensuring the flexibility of the lens, the wear resistance can be improved as much as possible, up to about 2.5.
STC2200 series strengthening solution
It is mainly composed of silicone resin and alcohol solvent and is used for polycarbonate (PC). Due to the refractive index of the cured coating, it is close to the refractive index of PC, so that no rainbow will be generated after the surface of PC is strengthened.
The main components of silicone resin, alcohol solvent, propylene glycol methyl ether solvent; good adhesion to PC; refractive index matching with PC, no multicolored after strengthening; has good wear resistance.
The main components are polyurethane resin, alcohol solvent and propylene glycol methyl ether solvent. It has good adhesion to PCTG(tritan), PC, TAC and PA substrates, excellent chemical resistance and good flexibility.
