SOLVING MIXED MATERIALBONDING CHALLENGES
Introducing a New Level of Design Flexibility

LIGHTER VEHICLES START WITH SIKA The trend towards lightweight structures in car body
construction has made mixed assembly of lightweight and composite materials a common strategy.
Our Sikaflex® and Sikaforce® Ultra High Modulus (UHM), one- and two-component elastic
polyurethane adhesive provides OEMs with an innovative alternative to spot welding or applying
rigid, inflexible structural adhesives to the body structures. UHM technology creates a new level ofdesign flexibility by allowing engineers to explore innovative uses of lightweight materials, while
ensuring designs and materials chosen can comply with all of the requirements for crash-resistanceand safety regulations.

This innovative adhesive family provides an industry leading solution to the most challenging assembly line bonding application;
providing exceptional performance during crash events, while accommodating the differences in material thermal expansion
and contraction properties (Δ ) of the different materials. Further, UHM technology directly contributes to car body stiffness
for improved vehicle dynamics. It is based on Sika patented and proprietary i-Cure® technology, which allows for curing
acceleration through the use of Sika®Booster products. The innovation is a key process enabler for mass production of vehiclearchitectures with mixed material design.

BONDING AND SEALING SOLUTIONSFOR EXTERIOR AND INTERIOR TRIMASSEMBLY
New Materials - New Options - New Possibilities
LIGHTER AND STRONGER VEHICLES START WITH SIKA Bonding of trim parts directly on theassembly line has opened new possibilities for car body design, while also simplifying andstreamlining assembly processes. Sika offers a full range of adhesive and sealant technologies fortrim parts assembly especially suited to the challenges presented; Sikaflex® and SikaForce® 1C and2C polyurethanes, hybrid technologies including silane terminated polymers and our proprietaryi-Cure® product family.
Typical applications include sealing and bonding of spoilers, antennas, bumpers, tailgates, side-panels, headliners, cockpits andeven roof rails. Potential applications are only limited by the designers imaginations.
Of special interest for these products is the drive to reduce body weight, which has led to greater use of alternative materials for
assemblies including aluminum, plastics and composites, as well as thinner metal panels.
Another Sika innovation; our well known Sikaflex®-ULM (Ultra Low Modulus) adhesives, specifically introduced for bonding verythin metal panels, without introducing typical read through effects common to adhesive materials. Sikaflex®-ULM leverages
the full advantages of our patented i-Cure® prepolymer base, providing consistent performance over the wide operating
temperature range.

THE GLASS REPLACEMENT LEADER
Full Service Portfolio for Professional Glass Replacement

STICK WITH THE LEADER - START WITH SIKA To most drivers, the windshield is just a window to
the world. To an automotive engineer, it’s part of an important safety system that helps keep
occupants safely in the vehicle in the event of a crash and plays an important role in enhancing thestructural stiffness of a vehicle. For Sika, both are key elements incorporated into the design of our
products, but there is much more to consider regarding vehicle glass replacement.
Glass replacement adhesives must meet stringent standards, like FMVSS 212, which defines performance requirements forpassenger crash protection and windshield mounting. Car manufacturers also have their own specifications related to safe driveaway time, modulus, antenna suitability and more; requirements that become ‘standard’ for glass replacement applications. With
our Sika®Aktivator, Sika®Primer, Sikaflex® and SikaTack® products, we support vehicles from the factory floors to the open roads
by offering a full range of professional repair products.
Our latest innovation for the automotive glass replacement market is the Sika® PowerCure System. This platform for accelerated
adhesives and sealants features an innovative dispenser, dynamic mixer and a full range of accelerated adhesives and sealants.
It delivers the precision and performance of the high-end pump systems found on automotive manufacturers’ production lines
but designed with good flexibility, ergonomic and handling characteristics for manual applications. Providing the fastest curing
adhesives with 30 minutes safe drive away time (SDAT) at an unmatched level of comfort for the user, PowerCure is the totalsolution for sealing and bonding applications.
Outside of windshield bonding, Sika's PowerCure technology is the foundation for further adhesive applications which may needlong open time or assured curing under a wide range of climactic conditions - such as battery box bonding in e-mobility production.
