Sodium Persulfate PCB Etchant features:
Chemical substance for recording printed circuits and copper. Unlike ferric chloride, sodium persulfate is colorless, odorless, does not stain clothes and does not turn blue when it runs out.
Easy to dissolve. It acts very regular with guarantee of contour sharpness. Mode of use: - Dilute in a plastic bucket, the contents of the envelope of 100 in 0.5 liters of water heated to 40-50ºC, or the ratio for a smaller PCB
- Do not store the solution in closed bottles
- It is corrosive, wear latex gloves
- Necessary for the homemade manufacture of printed circuits
- Care should be taken during digestion, as it is aggressive - especially for the eyes, skin and respiratory tract.
- Made in the European Union

Descripción: Silicone oil, also called silicone fluid, is a liquid with a greasy and sticky consistency.
It has the characteristics of being odorless and colorless, it is stable at high temperatures -50 ° C to + 200 ° C and has various applications.
It has high lubrication capacities and due to its low molecular attraction facilitates the spreading on different surfaces. Silicone Oil 300ml Spray features:
- Excellent dielectric properties
- It is used in different industrial processes as a lubricant (due to its greasy consistency)
- Particularly suitable for lubricating plastic and rubber parts
- Ideal as an insulating coating that does not harden
- High quality - Made in EU
