Roof Module Bonding

Today's fast paced automotive manufacturing processes demand that roof systems be bonded and transported to final assembly in a short time. This makes a high-strength bond during the initial curing process (known as green strength) essential for sunroof and panoramic assemblies to ensure the reliability and efficiency of the bonded system. Our product range includes a variety of polyurethane technologies that allow for fast handling AND durable joining. While more and more assemblies are designed with weight reduction goals, substrate bonding becomes more challenging; parts made from plastics and hybrids are more susceptible to marking. Our approved exterior solutions help to avoid bond line readthrough on thin and sensitive plastic parts.

Further, Sika pre-treatment systems help to ensure highly consistent and reliable bonds in the final assembly, while also offering easy application techniques. Sika® Primer-207 is not only a universal one-step primer but is also UV-detectable which enables the detection of pre-treatment for inline quality control. Sika pre-treatment agents help to ensure highly reproducible and safe processes. If in-house distribution or global supply chains require solutions with long open time, new Sika® Primer-219 fulfills demands on plastics.
