CALFIN ALUMETCH AP200
Alkaline aluminum etch system for consistent satin surface finishing
CalFin AlumEtch AP200 is a granular alkaline etching system formulated to produce a fine satin finish on aluminum and its alloys. The product is designed for controlled aluminum surface preparation, offering sequestering action that helps limit scale and sludge accumulation on process tanks and heating coils. Its low-level foam blanket also helps reduce the escape of caustic fumes into the workplace. CalFin AlumEtch AP200 is suitable for aluminum finishing operations requiring controlled etching, with recommended processing conditions of 4–8 oz/gal, 100–160°F (38–72°C), and an optimum treatment time of 5–10 minutes.

Applications
Aluminum Satin Etching
CalFin AlumEtch AP200 is designed to produce a fine satin etch on aluminum and its alloys. It can be incorporated into finishing processes where controlled alkaline etching is required before subsequent surface-treatment steps.
Aluminum Surface Preparation
The product provides an alkaline etching step for aluminum processing operations. Its defined concentration, temperature, and treatment-time ranges allow processors to establish controlled conditions according to their finishing requirements.
Controlled Aluminum Finishing Processes
CalFin AlumEtch AP200 supports aluminum finishing lines that require consistent bath management. The formulation's sequestering action helps control scale and sludge buildup during continued bath operation.
High-Volume Aluminum Processing
With a recommended operating range of 4–8 oz/gal and an optimum treatment time of 5–10 minutes, the product can be incorporated into established aluminum finishing operations requiring repeatable etching conditions.
Aluminum Treatment Before Subsequent Finishing
Alkaline etching can serve as an important preparation step within broader aluminum finishing sequences. CalFin AlumEtch AP200 provides the etching stage before subsequent surface treatments selected for the specific application.
Aluminum Finishing Bath Management
The product is designed with bath-control considerations in mind, including monitoring of free caustic and aluminum content. This allows processors to track bath conditions and manage the etching solution during operation.
