PU Scraper Blade - Solar Panel Screen Printing Squeegee

Product Description

Fiber Glass Board Squeegee For Solar

The traditional squeegee is all urethane rubber, which is printed for a long time,After the squeegee absorbs the solvent in the ink, the hardness is reduced, the expansion deformation, the printing angle α is unstable, and it is not suitable for precision screen printing. The Fiber Glass Board Squeegee is combined with the glass fiber board and the scraping glue, which has the elasticity of the scraping rubber and the support line of the glass fiber board. The long-time printing can maintain a stable printing angle and the printing ink thickness is uniform.
