Why TMF 81 is Practical for Rim Repair

Fast, secure masking is essential in rim painting and spot repair. The TMF 81 consists of HDPE film with an elastic cord and is positioned over the tire and rim. The corona-treated surface supports the absorption of overspray, ensuring the painting area remains more controlled.

Product Overview

Recommended Basic Settings and Reference Values

The following values are intended for guidance. The technical data sheet indicates that the stated values are averages and suitability should always be checked for the specific application.

• Temperature load: up to approx. 80 °C as a reference value.
• Wheel sizes: according to TDS suitable for approx. 15" to 22/23"; product page mentions 13" to 22".
• Maximum inner diameter: approx. 580 mm.
• Storage: indoor rooms, avoid UV radiation.
• Storage climate: approx. 20 °C ± 10 °C and 30–90 % relative humidity.

Professional Workflow: How to Use TMF 81 Correcty

1. Deflate the tire slightly so the tire bead can be controlled more easily.
2. Thoroughly clean and degrease the rim and tire area.
3. Carefully loosen the tire bead from the rim flange.
4. Press the tire down so the film can be positioned cleanly on the rim edge.
5. Place the TMF 81 evenly around the rim using the elastic band.
6. Release the tire in a controlled manner so the film sits securely.
7. Paint, let cure, press the tire down again, remove the film, and refill the tire.

Troubleshooting: Avoid Typical Problems

1. Film is not sitting cleanly on the rim edge

• Press the tire down more firmly in a controlled manner.
• Distribute the elastic band evenly around the rim.
• Check if the wheel size and inner diameter are within the appropriate range.

2. Overspray adheres unevenly

• Do not contaminate the film with silicone, grease, or cleaner residues.
• Only use clean, dry film.
• Check the spray distance and material application.

3. Film slips during painting

• Check the fit all around before painting.
• Bring the tire into the correct position.
• Do not create strong tension on one side.

4. Film is subject to excessive thermal stress

• Observe the temperature resistance of approx. 80 °C as a reference value.
• Check drying and oven parameters for material compatibility.
• Test beforehand if processes deviate.

Maintenance and Storage

• Store in a closed room.
• Avoid UV radiation.
• Recommended storage temperature: approx. 20 °C ± 10 °C.
• Keep relative humidity in the range of approx. 30–90 %.
• If stored correctly, the shelf life according to the data sheet is approx. 2 years.
