PLASTIC PARTS FINISHING

Paintable plastic parts are ABS plastic parts.
Painting
Rigid or hard ABS plastic needs no primer coating.
General acrylic lacquers can be painted properly over hard ABS
plastic in terms of adherence.
1) Use cleaning solvent for paint finish to wash each part.
2) Apply conventional acrylic color lacquer to part surface.
3) Follow lacquer directions for required drying time. (Proper dry-
ing temperature range is 60 to 70_C).
Reference
Plastic parts employ not only ABS (Acrylonitrile Butadiene Styrene)
plastic but also polypropylene, vinyl, or the like plastic. Burning test
method to identify ABS plastic is described below.
1) Use a sharp blade to cut off a plastic sliver from the part at its
hidden backside.
2) Hold sliver with pincers and set it on fire.
3) Carefully observe condition of the burning plastic.
4) ABS plastic must raise readily distinguishable back smoke while
burning with its residue suspended in air temporarily.
5) Polypropylene must raise no readily distinguishable smoke
while burning.
