Application Temperatures

Can I overheat the vinyl?

It is possible to overheat the film during application and postheating stages. Be careful if the film becomes too hot it can discolour and crease, especially in recesses when stretching.

What is the correct temperature for post-heating?

Post-heating temperatures will vary according to manufacturer recommendation for each film, dependant upon its make up. For guidance, please follow the suggested maximum temperatures for post-heating on the relevant product pages of this website.

What temperature is recommended for wrapping?

The ideal application temperature range is 15-25ºC, which includes the vehicle, vinyl and ambient temperature. The optimum temperature for most wrap applications is 18-21ºC, especially for 3M films with Controltac adhesive. However, 3M 1380 also requires a higher application temperature of 20ºC. The film and vehicle should be stored overnight at this temperature to acclimatise before application.

How do I apply 3M Controltac wrapping films?

The wrapping environment is critical for Controltac application. If temperatures are too cold, the beads in the adhesive may not be activated as the vinyl becomes too rigid at lower temperatures. The adhesive can become too hot at higher temperatures, again affecting the performance of the Controltac beads.

Controltac applications also require firm squeegee pressure. 3M gold applicators with a cotton squeegee sleeve are ideal for applying harder pressure, without risking scratches or marks on the film. Felt edged squeegees are also suitable, but they will not last as long.

Do I need to post-heat the vinyl?

Post-heating sets the film in place, removes the vinyl’s memory and makes the adhesive flow to gain instant maximum adhesion. Using an infrared thermometer ensures that the correct temperatures are reached when post-heating. You should ensure you move the heat gun away from the vinyl before reading the temperature to ensure a correct reading.
