I hope this is in the right place.
I want to take Krylon off of my AR furniture before I duracoat it. I was going to use Acetone to take the paint off. After that I think I need to clean it off but I don't know what is the best product to work. Is Acetone good to get the Krylon off? What do I use to clean off the Acetone and get ready for Duracoating? Any ideas and suggestions would be greatly appreciated. Thanks, Bonk |

Acetone and plastic usually don't play well together.
I would try something else before I would resort to acetone. If you do go the acetone route, test it first on a small inconspicuous area. Acetone doesn't really need to be clean off, it is in fact a cleaner itself. I clean my parts with alcohol prior to painting with Norrells. |

Nylon (actually it is Zytel) and the Bakelite are resistant to acetone. Nylon's peptide bonds are not affected by acetone and Bakelite is a thermoset with similar bond properties. The A2 stock and pistol grip are Zytel (a nylon) and the handguards are Bakelite (phenol-formaldehyde)
Plastics like polycarbonate, ABS, polystyrene, polymethyl methacrylate (Plexiglas) are sensitive to acetone and most ketones. Thermoplastics like polyethylene and polypro are very resistant to ketones and most hydrocarbons (plastic fuel tanks, for example). The only issue with using acetone for cleaning off Krylon paints is they are too powerful and can force pigments into the pores of the polymer. Nylons WILL stain and absorb pigments. And Bakelite to a lesser extent. But tha acetone WILL fully degrease such plastic parts and will help adhesion. |
