01 / Product brief

Rework Rejected Parts Without Abrasive Blasting

High-pH alkaline paint and scale stripper for rework of miscoated, over-cured, or defective painted components. Saponifies and lifts cured powder coat, liquid paint, and epoxy primer without attacking the base metal. Designed for tank or spray application at 60–80°C on steel, cast iron, and aluminium substrates.

Selective chemistry saponifies organic coatings while leaving base metal intact — avoids abrasive methods (shot blast, grit blast) that can stress-relieve heat-treated parts or alter surface roughness. Single-tank immersion strips complex geometries including blind holes and internal passages.
