2. Operating Instructions
Screen Pre‑treatment: Fully clean ink and block‑out compound from used screen; keep mesh wet. Ink residue will seriously reduce stripping performance.
Prepare working solution: Recommended mixing ratio: 100g powder to 5‑7L clean water. Stir fully until powder dissolves completely. Increase concentration for stubborn old stencils; 2% solution is suggested for automatic decoating machines.
Decoating operation: Apply working solution evenly on both print side and squeegee side with sponge or soft nylon brush, or immerse whole screen into solution. Allow 2‑5 minutes for emulsion to swell and soften. Never let solution dry on screen mesh.
High‑pressure rinsing: Rinse both sides thoroughly with high‑pressure water gun while chemical is still wet to wash away softened emulsion. If ghost/haze remains, apply haze remover paste then rinse completely with clean water.
Dry screen for reuse: Dry screen at 35℃‑40℃, maximum temperature 42℃. Make sure screen is fully dried before next coating operation.
Important note: Confirm no chemical residue after decoating. Residual salt will cause pinholes and poor emulsion coating in follow‑up process.
