Plating on Plastics – Plastic Metallization
HESSOPLAST® for electroplating on ABS, PC/ABS and technical plastics.
Benefits of HESSOPLAST® POP Pretreatment for Plastic Metallization
- Outstanding cost-effectiveness in plastic electroplating
- PFOS-free and resource-saving process management
- Very low palladium consumption in the activator process
- Lowest ammonia concentration for simplified wastewater treatment
- Short cycle times for efficient POP processes
- Easy integration into modern direct metallization lines
- Suitable for decorative and functional coatings on ABS, PC/ABS and technical plastics
The PFOS-free HESSOPLAST® POP pretreatment provides the basis for efficient and reliable plating on plastics. With very low palladium consumption, short cycle times and a low ammonia concentration, the system supports stable processes for the electroplating of ABS, PC/ABS and engineering plastics. This makes HESSOPLAST® particularly suitable for decorative and functional applications in the sanitary, automotive and fittings industries.
