What plastic can be painted

Not any kind of plastic can be painted.

You must pay attention to the marking on the part, which indicates the material of manufacture, before applying the dye.

• PS, PC, PE, PP (polystyrene, polycarbonate, polyethylene, polypropylene, respectively) – materials are not lending to staining.
• ABS, PVC (ABS-plastic, PVC). Can be painted, but before painting, plastic needs to be primed.

The majority of the car’s parts are made of plastic, which can be painted, though primer isn’t always required. There are two methods to determine if the product needs to be primed:

1. The part is placed in the water. The plastic drowned, then it is not necessary to primer. If it does not drown, the surface is mandatory.
2. A cleaned piece of part is taken, set on fire. When the flame is calm, you need a primer. If there is black smoke, you can paint plastic without priming.

Successful staining conditions

1. The plastic to be stained should be clean and dry.
2. Previously, the plastic needs to be primed. Soil with high adhesive abilities is used. Can be applied with rubbing or spraying. Stained only after the final drying of the primer.

You must adhere to the guidelines below in order to prevent paint from chipping and to properly fix it.

• Carry out painting with air humidity no more than 80% and at a temperature above +18 ° C.
• Use the dye of the same temperature as the plastic itself.
• Apply dye with a layer of 60-120 μm. Too thin layer will reduce stability, and the thicker will dry for a long time and affect the visual form of plastic.
• The drying of the paint should take place at a temperature of +18 … +60 ° C.
• For complete drying, you need to give at least 5 days. The higher the humidity and colder air, the longer the drying lasts. Before the start of polymerization, it is not recommended to cool and moisturize the painted object.
• Soft plastic is best painted with elastic enamels containing plasticizers, then the layer does not crack when the shape of the object/part changes.
• Solid plastic can be painted with enamels based on acrylic.
