Product Description
Coomcool Form ST 220 is a low viscosity, chlorine and heavy metal free metal stamping fluid. It is a mixture of lubricity additives in a low odour dearomatised hydrocarbon solvent base.
Advantages
- Fluid based on a low odour dearomatised hydrocarbon solvent.
- Quick drying, low residue characteristics can eliminate the need for inter-process cleaning.
- Contains lubricity additives to maximise punch life and provide excellent surface finish. Helps to minimise the costs associated with tool re-polishing.
- Can provide limited inter-process corrosion protection.
- Chlorine and heavy metal-free technology improves the environmental profile and minimises waste disposal costs.
Applications
Coomcool Form ST 220 can be used in light duty sheet stamping operations where very low residues are required,eliminating the need for inter-process cleaning. The fluid is especially recommended for use in electrical stamping applications as well as on light gauge uncoated steels and zinc coated steels and yellow metals.
