hardware store acrylic solvent cement Using Liquid Paint Stripper as Acrylic Cement

mz sept plastics 150x150 Using Liquid Paint Stripper as Acrylic CementUnless your application is critical, cheap liquid paint stripper from the hardware store (not the gel, paste, or color-changing varieties) is a fine substitute for commercial acrylic solvent cement. Comparing one MSDS to another, we see that each product is about 75 wt% dichloromethane (AKA methylene chloride), which is the “active ingredient” that softens the plastic and allows it to weld. Purpose-made acrylic solvent is a bit thinner, in my experience, and evaporates a little faster, and contains trace amounts of acrylic monomer that may result in a slightly stronger bond, but for most practical purposes I have not found these qualities to justify paying twice as much for it.
