Products Description
Double-sided acrylic foam tape EX4008 for automotive consists of black foamed acrylic adhesive with additional acrylic adhesive on both sides for automotive surfaces like powder coatings and nanoparticle-based clear coatings. Typical applications are attachments of rigid add-on parts such as stone chip moldings, fender moldings, or wheel arch extensions.
Product Feature
* Acrylic plus tape EX4008 demonstrates a very good adhesion to modern surfaces for automotive which are difficult to adhere.
*One acrylic foam tape side is covered with a special, high performance adhesive for automotive paint systems, the acrylic adhesive offers good adhesion to low-energy-surface substrates without additional primer treatment.
*The foam core gives good wet-out properties and adaption to complex geometries.
*Additional EX4008 offers good internal strength and good long-term stability.
Products Advantages
The automotive acrylic plus tape is manufactured using a special process of producing a homogeneous system of high performance acrylic adhesive for new paint systems.
The product can be used for numerous applications on exterior vehicles and can balance large part deviations. Further, it is suitable for modern and robot-based applications.
The unique viscoelastic nature of acrylic foam gives it a high cohesive strength, combined with excellent shock and weathering resistance. To optimize bond strength, the surfaces must be clean, dry, and smooth with a good fit between the part and substrate. Decisive for good adhesion performance is full surface contact between tape and substrate. Contact is achieved by pressurization. In practice a pressure between 10 - 50 N/cm² is usually needed and an application temperature between 18 - 40 °C is also necessary. During application, add-on parts and tapes must have the same temperature.
