Installation of Cast vinyl in cold weather
How cold temperatures affect cast vinyl, adhesive performance, and installation, and what installers can do to improve application results.
Cold weather can make cast vinyl more difficult to install. As temperatures decrease, the film becomes stiffer and less conformable, while the adhesive loses initial tack and does not wet out as readily onto the substrate. Lower temperatures can also increase the time required for the adhesive to develop bond.
Condensation is another concern. Bringing a cold vehicle or substrate into a warm installation area can cause moisture to form on the surface. The substrate must be clean and completely dry before application.
Temperature Matters
Temperature recommendations vary by product. Always refer to the applicable Arlon Product Information Bulletin for the optimal application temperature range and product-specific installation requirements.
Do not rely on room temperature alone. A vehicle brought inside after sitting outdoors may remain considerably colder than the surrounding air. Allow enough time for the film and vehicle to acclimate, and verify the temperature of the actual application surface before beginning.
Adhesive Wet-Out
Pressure-sensitive adhesive requires sufficient pressure and temperature to make intimate contact with the substrate. This is commonly referred to as wet-out.
When the adhesive is cold, reduced tack and wet-out can make initial adhesion more difficult. Bringing the film and substrate into the appropriate temperature range helps restore normal application characteristics. Adequate squeegee pressure is also important, and additional pressure may assist under colder conditions.
Pay particular attention to rivets, seams, edges, recesses and other areas where the film is subjected to greater stress.
After Installation
Where possible, allow the completed vehicle to remain in the controlled installation environment rather than immediately returning it to very cold outdoor conditions.
Follow the applicable Arlon product and application instructions for post-heating, particularly in areas where the film has been stretched or conformed.
Successful cold-weather installation depends on the condition of the film, substrate and installation environment, not simply the temperature of the shop.
