Plastic Parts Paint Repair - Plastic Part Types and Characteristics

1.	Plastic Part Types and Characteristics

Before repairing plastic parts, confirm the temperature for forced (heated) drying and solvent resistance.

Refer to the chart below to avoid heat or solvent damage to plastic parts.

NG= No Good - Do not use

Heating plastic parts to temperatures at or above the ‘‘Heat resistance temperature’’ may deform them.

For two plastic parts constructed of the same material, heat and solvent resistance may differ based on the polymerization.
