ALUMAL ETCH 235

ALUMAL ETCH 235

ALUMAL ETCH 235 is an alkaline E-6 etch additive designed to operate at low and high caustic operations. It contains purifiers and guarantees high bath stability.

Elevated appearance

Architectural applicators appreciate ALUMAL ETCH 235, as it effectively hides dye and flow lines and produces a defined degree of reflectivity or a matte satin effect. 

Operational advantage

ALUMAL ETCH 235 runs as a low-foaming formulation even with large tank loads.

Cost effectiveness

The viscosity of the etching bath is decreased, minimizing drag-out losses.
