EXECUTIVE SUMMARY
For many years, SikaForce® adhesives have proved their excellence across numerous projects andapplications where flexible or (semi-) structural joints with high demands on long-term robustness andweathering resistance are given. In the automotive industry these requirements are associated withshort cycle times and a wide range of different materials. With SikaForce® adhesives, a highly
industrialized and automized level performance in joining assembly parts such as spoilers, liftgates,roofs and decorative components can be achieved.
Our newly released SikaForce®-825 L04 adhesive further complements the strong SikaForce® portfolio.
SikaForce®-825 L04 is a fast and flexible adhesive offering new advantages to customers requiring faststrength build up, long open times and/or solutions for critical substrates difficult to bond and prone
to stress cracking.

ADVANTAGES AT A GLANCE•Process simplification due to adjusted flow behavior and the correct balance of open timeand strength build-up•Faster processes can be achieved with heat acceleration – Curing-On-Demand (COD)•Superior sagging behavior allows for high applicable bead thicknesses and a remarkable
tolerance compensation•No plasticizer in the formulation minimizes risks for Environmental Stress Cracking (ESC)KEY DATAPROPERTIESTYPICAL VALUES

NEWS FROM THE MARKET
A new Ford SUV program in the US included an iconic roof design combined with innovative materials
and lightweight structures. In fulfillment of the main requirements such as short cycle times, goodtolerance compensation, and ESC risk minimization on sensitive bonding partners, only SikaForce®-825
L04 delivered the right performance. The result of a strong global network in all regions and close
cooperation between all parties and experts allowed Sika again to support customers in writing successstories.

OUTLOOK
Further new SikaForce®-8XX products in our pipeline – stay tuned!
