PPRC supported an investigation into styrene content in auto body fillers. The request for information came from a regulatory agency that has styrene as a priority chemical for reduction in their jurisdiction.
Styrene is found in many different products, including auto body fillers, or putties, which are some of the most commonly used consumables in auto body shops. Putties fill the dents, scratches or irregularities an auto body surface so that, after sanding, the surface is perfectly matched and integrated and maintains integrity for the function of the car exterior. For instance, the repair must hold up in exposure to sun, rain, wind, and very hot or very cold temperatures.
In auto putties, styrene acts as a key component that allows the putty to cure and harden quickly, essentially serving as a reactive solvent that helps the resin molecules cross-link and solidify, enabling the putty to fill gaps and imperfections on car bodies effectively. There are a very wide range of putties.
Non-styrene fillers can reduce harmful styrene emissions during auto body repair, minimizing employee exposure and air emissions.
