How Chemical Paint Stripper works? Vitarag Chemicals is a renowned manufacturer of PCR 01 Paint Stripper 1. Chemical Formulation: Paint strippers contain active ingredients that can be solvents, caustic agents, or bio-based compounds. These ingredients work to penetrate and weaken the bonds between the paint and the substrate. 2. Penetration: When applied to a surface, the chemical paint stripper penetrates through the layers of paint or coating. This penetration is crucial for effectively breaking the bond between the paint and the substrate. 3. Softening: The paint stripper softens the paint or coating by disrupting its molecular structure. This softening allows the paint to be scraped, brushed, or washed away from the surface.
