Sodium hydroxide, commonly known as lye or a related term, is a highly alkaline chemical compound employed for a variety of industrial and domestic purposes. One notable application involves its use to detach coatings from surfaces. This process leverages the strong base properties of the chemical to break down the bonds within the paint film, facilitating its removal.
The utilization of this chemical offers advantages in terms of its effectiveness on multiple layers of coatings and its ability to soften difficult-to-remove paints. Historically, it has been a preferred method for stripping paint from intricate surfaces where mechanical abrasion may be impractical or damaging. However, its highly corrosive nature necessitates stringent safety precautions and appropriate disposal methods.
