DANGER
METHYL ALCOHOL IS BOTH FLAMMABLE AND TOXIC. HANDLING MUST TAKE PLACE
AWAY FROM FLAMES, SPARKES AND HEAT SOURCES. IN GENERAL AVOID CONTACT
WITH THE MOUTH AND AVOID INHALING ITS VAPORS.
By dissolving boric acid with methyl alcohol (as explained hereunder) you will obtain a green flame
with high deoxidizing power, that is indispensable for braze welding operations, since it ensures
optimal flow and penetration of the solder. In the thermic treatments, methyl alcohol is normally
used in its pure state.
1) Pour the desired quantity of methyl alcohol into a plastic container provided with hermetic
seal cap.
2) Add the boric acid in the form of flakes in a proportion of 15- 20 grams. (as a maximum)
per each liter of methyl alcohol.
3) Close the container, shake it up and wait until the product is fully dissolved, before using.
