Preservation
Preservative	Properties	Durability		Depreservatives	Order code
		Indoor storage	Outdoor storage
Cleaning emulsion	Simple preservation	up to 3 months	–	Aqueous cleaners	Standard
Spray oil	Anti-corrosion agent	up to 12 months	up to 3 months	Aqueous cleaners, solvents	B31
Tectyl 846 or similar	Long-term preservation, wax-based	up to 36 months	up to 12 months	White spirit, special solvents	B28

¹⁾ The hub keyways are designed to DIN 6885 Sheet 1 "High Form" On some sizes, which are marked in the dimension tables, the keyway is designed to DIN 6885 Sheet 3 "Low Form"

²⁾ VCI films used as export or long-term packing protect against corrosion. The costly removal of e.g. Tectyl 846 is thus unnecessary.
