Embodiment Construction

[0050] method

[0051] A 2018 Chevy Traverse was used as a test vehicle. The vehicle represented a demanding test object because the bonnet front was particularly bulbous. Installation involves first cementing one side of the PPF sheet with a tackifying solution, and then stretching significantly across the surface and sticking to the other side, then installing the front, ie pulling it into place for squeegeeing. The hood surface was prepared prior to installation by washing away dirt, dirt and oil with soapy water and rinsing with more water, and a new piece of PPF was used for each fluid tested. Record the opinion of an experienced installer / instructor during and after each installation. Apart from obvious signs such as smell, the installer does not know which solution to test in a given situation.

Abstract

The present invention is directed to tack solutions comprising formic acid, and their use in applying adhesive-coated films to substrates. In particular, paint protection films (PPFs) can be applied to vehicle bodies using the solutions of the present invention.

Description

technical field [0001] The present invention relates to tack solutions and their use in applying films to substrates such as vehicle bodies. [0002] Background of the invention [0003] Films are typically applied using slip solutions, such as window films applied to automotive windows. In such a process, the release liner is first removed from the film to expose the compatible adhesive layer and a slip solution is applied to prevent the film from sticking to itself But not permanently mounted on the window facilitates physical movement of the film across the window surface with reduced friction. Final and complete bonding typically only occurs when the slip solution is squeezed away from the space between the adhesive and the window and any remaining slip solution residue has evaporated. [0004] Paint protection films (PPFS) can also be applied to bodywork using slip solutions, but proper adhesion of PPF usually requires the use of tackifying solutions. The paint protec...
