Abstract

The product concept is a one-step surface cleaner for vehicle vinyl wrapping market, where current products in the market require a 2-step process, using chemicals that are highly volatile, made of hazardous and dangerous chemicals. The one-step cleaner not only is more user friendly, it also saves time in the preparation process that often is the most time consuming during vinyl installation (pain point). The working prototype utilizes green solvents (such as coconut methyl esters), that has strong cleaning power as conventional solvents like toluene and naphtha, but is biodegradable, low VOC, and non-carcinogenic.

One-Step Surface Cleaner for Vehicle Vinyl Wrapping

One-step surface cleaner designed to remove contaminants on a vehicle surface (painted panels) prior to vehicle vinyl wrapping that leaves no residues. These contaminants are usually residual waxes or silicone based coatings on the vehicle that were not removed in the prior car washing step. The conventional method of preparing a vehicle prior to vehicle wrapping is a 2-step process; a solvent cleaner followed by an alcohol cleaner. These cleaners are high in volatile organic compounds (VOC) and can be a health hazard for the vinyl installers when working in a closed and small confined space and are hazardous, requiring the need for basic personal protective equipment (PPE). The proposal is a surface cleaner containing a green solvent, coconut methyl ester that has low VOC, biodegradable, non-carcinogenic solvent that is effective for cleaning and degreasing, and is safe for use on the painted surface of the vehicle. Additional features include; scent (eg. citrus, coconut, ocean scent etc.) and the choice in packaging (aerosol can, trigger spray) and trigger design can vary the dispersion of the cleaning solution (dispersion of cleaner, drip-free, foaming etc).

Film adhesion failure or ‘film popping’ in vehicle wrapping can be caused by a combination of reasons, some of the most common reasons are choosing the wrong film, overstretching the film, insufficient post-heating, and contamination on the vehicle among others. One of the key preventions of film popping (when correct installation techniques are used) is using the correct cleaning preparation steps as part of the installation. To prepare a vehicle for vinyl wrapping, all badges are removed, the vehicle is washed thoroughly with a harsh car wash and at times more diligent installers use a clay bar to remove embedded contaminants. Once the vehicles is washed, it is dried and setup indoors for installation. Up to this stage of preparation, there may still be traces of contaminants on the vehicle that are not visible to the naked eye and these contaminants could be oils, pollutants, silicon, wax, that may interfere with the adhesion of the vinyl film. The common practice is to remove these residual contaminants in two steps: first step is with a solvent cleaner to break down the contaminants, such as cleaners that contain toluene, naphtha, n-hexane, xylene, heptane, ethylbenzene with a clean microfiber cloth. Followed by an alcohol cleaner, such as cleaners that contain predominantly isopropyl alcohol with a clean microfiber cloth, to remove the residual oils remained from the solvent cleaning step. Commonly available solvent cleaners are harsh solvents that require PPE to handle with high VOC and exposure to these hazardous and dangerous chemicals are common as PPE is often neglected and in this application, it is applied in an enclosed space. Aside from the health risks of using traditional solvent cleaners, cleaning a standard Sedan ve...
