Paint strippers

Paint stripper is a chemical agent used to remove paint coatings from the surface of objects. The following is an introduction to its composition, classification, characteristics, usage methods and precautions:

Main Ingredients

Organic solvents: such as dichloromethane, chloroform, benzene, toluene, xylene, etc., are the main components of paint strippers. They can dissolve resins and other film-forming substances in paint, thereby achieving the purpose of removing paint.

Solvent co-solvents: Commonly used ones are ethanol, acetone, etc., which help organic solvents better penetrate into the paint coating and enhance the paint stripping effect.

Activator: Generally an organic acid, such as formic acid, acetic acid, etc., which can accelerate the dissolution and stripping process of paint.

Thickeners: such as carboxymethyl cellulose, polyvinyl alcohol, etc., can make the paint stripper have a certain consistency, making it easier to apply to the surface of objects and prevent flowing.

Corrosion inhibitors: such as hexamethylenetetramine, are used to inhibit the corrosion of paint strippers on metal substrates and protect the surface of the treated object.

Classification

Acidic paint stripper: It has strong corrosiveness and can strip paint quickly, but it has a certain corrosive effect on metals. It is suitable for stripping paint on surfaces that do not require high corrosion resistance.

Alkaline paint stripper: It is relatively less corrosive and less corrosive to metals, but it strips paint more slowly and is often used in situations where higher requirements are placed on metal surfaces.

Neutral paint stripper: It has milder properties and is less corrosive to metals and most materials, but its paint stripping effect may not be as good as that of acidic or alkaline paint strippers. It is suitable for stripping paint on some special materials or surfaces that are sensitive to corrosion.

Features

Efficient and fast: It can dissolve and remove paint coatings in a shorter time, greatly improving work efficiency.

Wide range of applications: can be used to remove paint from the surfaces of various metals, wood, plastics and other materials.

Easy to operate: just apply or soak the paint stripper on the surface of the object to be treated to remove the paint without complicated equipment and process.
