Chemetall Ltd has introduced Gardolene D 6870, a new addition to its range of metal surface treatment technology. Gardolene D 6870 is reported to be a new chrome-free post-rinse specially formulated for use after phosphate pretreatments on steel, zinc-coated steel and aluminium. Chemetall informs us that this product will substantially improve performance characteristics of any subsequent paint coating. Gardolene D 6870 is said to be suitable for use following zinc phosphating or alkali-metal phosphating. It may be applied either by spray or by immersion, and is supplied as a one-pack liquid concentrate.
Following completion of the phosphating process and a water rinse, the work is sprayed or immersed in the Gardolene working solution for around 30 seconds, at a temperature normally within the range of 20úC to 45úC, depending on the nature of the work being treated. Following this treatment, the work either may be rinsed in deionised water prior to painting and/or drying, or may be used as a no-further-rinse process. The Chemetall engineers will be able to advise on whether or not this final rinse stage is required, as well as the most suitable temperature for the particular installation and nature of the work being processed.
