Highly reflective inks

Highly reflective inks


Product introduction

High-reflective ink is the latest water-based high-reflective layer developed by our company for the backplane of photovoltaic double-glass modules. The overall performance is excellent, with excellent low shrinkage and high reflectance, which can effectively increase the power generation efficiency of the components.


Product features

Good adhesion and high hardness;

The screen plate is 150-250 mesh, the printing performance is good, and it is not easy to have defects.;

Water-based inks are lead-free, environmentally friendly, and have no harmful gas volatilization.


Applications

It is widely used in the back panel glass of photovoltaic modules to prevent the sun's rays entering the module from penetrating the back panel glass and losing, so that most of the light enters the battery cell, thereby effectively increasing the power generation of the module.
