Temperature Resistance
Larger sunroofs increase the amount of UV light entering car interiors, which in turn increases temperature levels. This means door panel adhesives must offer higher temperature resistance in order to maintain performance and functionality.Aging Performance
Aging performance is another key factor when considering automotive door panel adhesives. Car doors are subjected to a range of harsh environmental conditions over many years. It’s important to assess an adhesive’s ability to maintain physical, mechanical and chemical properties throughout the vehicle’s life. This will also impact the door panel’s aesthetic appeal to consumers.Smart Adhesive Options
