Two face thin roller coating machine

Model:  SL-TRST
Function:  it applies the two application rubber roller and doctor stainless steel roller up and down to cover the liquid paint on two face of sheet circularly evenly, design special conveyor after coating to prevent harm paint layer on the back of sheet.
It is suitable to fine coating flat sheet which very thin and slight, low coating effect requirement of sheet back.

· Application sheet:
  metal plate, wood veneer, glass, etc.
· Application paint:
  UV, water based paint, PU, PE, NC, AC, special paint, etc.
