Ferric Chloride (FeCL3) - ANHYDROUS
Normally marketed content - 150 to 200 grams, to be dissolved in 1/2 liter of cold and ordinary water, in the concentration of 35 to 40%.
Popular Name: Iron Perchloride.
Abbreviation for Iron Perchloride: IP.
Note: For use only in the manufacture (corrosion) of Printed Circuit Boards.
UN number = 1773.
Appearance (in natura): Black powder, which may be stoned and with yellow granules.
Fire - Not flammable.
Caution: When handling chemical products, always use the appropriate safety equipment and well ventilated areas!
- If swallowed, induce vomiting and drink plenty of water or milk of magnesia. Seek immediate medical attention, especially if there are complications, informing the nature of the product, time of exposure and amount ingested;
- In case of contact with the product, wash the affected area with plenty of water in abundance for at least five minutes;
Note: May cause irritation and dry skin.
- In case of eye irritation, wash with plenty of water for at least five minutes. Looking for medical help immediately, especially if there are complications, informing the nature of the product and the time of exposure;
Note: In the case of the respiratory tract, it releases little acid vapor, causing little effect but, in case of complications, immediately seek medical advice, informing the nature of the product and the time of exposure;
Recommendations and Care:
- If you splash on your clothes, first wipe it with water and then immediately wash it with soap and water, but the stain will not come out;
- Do not use metal containers or utensils;
- Keep out of reach of children, the elderly, animals, etc .;
- Do not store the solution in Coke or Pepsi bottles, given the similar appearance of the products;
- Store the solution in well-capped and labeled container;
Step by step:
01 - Put half a liter of cold water in a vessel of reinforced plastic or glass;
Caution: Never use metal containers or utensils!
Note: If splashes fall on clothing, first wipe it with water, and then immediately rinse with soap and water, but the stain will not come out!
Note: Always dissolve the total contents, since the powder is very difficult to be isolated from the humidity, being easier to store the solution.
Note: Initially the solution will turn brown, ending up with the color similar to that of the coffee;
Attention: There will also be slowly self-heating that can reach 70 ° C due to the exothermic reaction.
Note: In order for the corrosion to be good, the copper of the Printed Circuit Board must be cleaned with dry steel wool before drawing (drawing).
Caution: For greater safety, always perform corrosion with the cold solution below 40 ° C.
Note: Using the cold solution at room temperature makes the corrosion more time consuming, but much safer because there is no risk of the paint leaving the printed circuit board.
Caution: Be sure to label the contents of the bottle!
Attention: The solution will be at room temperature and should remain.
Note: Solution weakens with use, not over time.
