Paint removal chemical




Methylene chloride (also known as dichloromethane or DCM) is commonly used in paint removers due to its strong solvent properties. Here’s how it works for paint removal:

Mechanism of Action:

1. Penetration: Methylene chloride penetrates the layers of paint or coating.


2. Softening/Breaking Bonds: It breaks down the chemical bonds in the paint polymers, softening the material.


3. Lifting: Once softened, the paint bubbles up or lifts from the surface, making it easy to scrape or wash off.



Formulation:

It’s usually mixed with other ingredients in commercial paint strippers, such as:

Thickening agents (to cling to vertical surfaces)

Surfactants (to enhance wetting)

Inhibitors (to protect the underlying surface)

Other solvents for improved performance



Usage Tips:

Apply with a brush or spray in a well-ventilated area.

Wait for the paint to bubble or lift (this can take a few minutes to an hour).

Scrape off the paint using a putty knife or scraper.

Clean the surface thoroughly afterward.


Safety Note:

Methylene chloride is toxic and can be fatal if inhaled in high concentrations. It's:

Volatile (evaporates quickly)

A respiratory and central nervous system depressant

Banned or restricted in some countries or for consumer use (like by the U.S. EPA)


Always use PPE (gloves, goggles, respirator) and ensure good ventilation.
