Rigid Plastic Part Repair Materials
General Plastic Repair
| WARNING | In order to reduce the risk of personal injury when exposed to toxic fumes while grinding, cutting, or applying repair material on any type of sheet molded compound or RIM rigid plastic, observe the following guidelines: Work in a properly ventilated area Apply protective cream to any exposed skin Remove any mixture that comes into contact with skin Wash skin with cold water to remove glass and resin dust Use a sander with a vacuum attachment Follow the repair material manufacturer's instructions Also, always wear the following: An approved respirator, or air supplied respirator Eye protection Rubber gloves Earplugs Protective clothing |
The following procedures should be followed when repairing all types of thermoset plastic
- Follow the manufacturer's application and curing recommendations.
- Do not intermix systems. Use the supplies and the repair materials from the same manufacturer.
- Clean the inner and outer surfaces of the repair area with a soap impregnated scouring pad in order to remove any dirt or mold release agent.
- Clean the area with a wax and grease remover, using only enough of the remover to dampen a cloth. Allow the panel to dry thoroughly.
- Remove the surface finish from the area to be repaired. Adhesives are designed to adhere to the plastic substrate, not the finish.
- Prime a metal surface before applying the repair material.
- Inspect the rear side of the work area before making repairs in order to avoid possible damage to wires, motors, etc.
Scheme 79
Plastic parts can be identified by the SAE code, which is usually found on the rear of the part, and/or by the characteristics of the plastic. Knowing the type of plastic aids in selecting the proper repair materials and in selecting the proper repair procedure.
Look for the SAE code stamped into the part.
Code Found
Match the code to those in the plastic identification chart to determine whether the plastic is thermoplastic or thermoset plastic, and whether the plastic is rigid or flexible. Refer to Plastic Identification and Refinishing Systems .
No Code Found
| WARNING | Do NOT use a plastic burn test to distinguish the type of plastic. The burn test produces vapors which are harmful. |
Perform one or both of the following tests to determine if the part is thermoplastic polyolefin or thermoset non-polyolefin.
Float Test
- Cut a shaving of plastic from the back of the part. The shaving should be free of mold release agents and paint.
- Place the shaving in a container of water. Thermoplastic polyolefin floats. Thermoset non-polyolefin sinks.
Abrasion Test
- Sand a spot near the damaged area with Grade 36 Roloc Disc.
- Thermoplastic polyolefin material melts or frays when sanded.
- Thermoset non-polyolefin material sands cleanly.
Thermoplastic and thermoset plastics can be either rigid or flexible. Thermoplastic plastic parts are best repaired with a hot iron plastic material-feed welder, but are usually replaced. Thermoset plastic can be repaired with epoxy or other more rigid 2 package repair material.
