Hybrid Power for Your Windshield Replacement
Vehicle sealing and bonding
Sika Hybrid Technology combines the power of polyurethane strength with the simplicity of MS polymers.
Sikaflex PUR-Hybrid products for industrial applications are well known due to their excellent workability and good adhesion properties on a multitude of substrates without any pre-treatment. PUR-Hybrids are additionally free of isocyanate, PVC, solvents and silicon and therefore fulfill highest health and safety requirements.
PUR-Hybrids
In vehicle sealing and bonding PUR-Hybrids are already well established: Sikaflex-552 AT is a universal usable multipurpose adhesive. Sikaflex-527 AT, Sikaflex-521 UV and Sikaflex-515 are typical sealants which can be used depending on required properties like excellent overpaintability, highest UV resistance or optimized performance-price ratio.
New OEM windshield adhesive, Sikaflex-556
In order to expand Sika’s PUR-Hybrid product range a new OEM windshield adhesive, Sikaflex-556, was introduced.
Sikaflex-556 is an OEM approved high-performance windshield adhesive based on Sika’s PUR-Hybrid Technology. The adhesive is a high modulus adhesive which can easily be applied at room temperature with common hand guns.
The new product offers all typical PUR-Hybrid product performances, like excellent workability broad adhesion profile and highest health and safety standards. Additionally Sikaflex-556 offers 3 hours safe drive away time*.
This was tested under harsh test conditions in order to guarantee highest safety security even only 3 hours after windshield replacement. The fulfilling of the save drive away time was finally confirmed by real crash test.
Sikaflex-556 for bonding in vehicles
Sikaflex-556 is based on Sika’s black-primerless technology. For windshield replacement a simple cleaning/activation of the ceramic coated glass with Sika Activator PRO or Sika Activator-205 prevents displacement of the windshield in case of a crash. Sikaflex-556 is, however, positioned as a multi-purpose adhesive and can be used for other applications than only vehicle glass replacement. Due to the excellent adhesion properties on various substrates Sikaflex-556 can be used for all kind of bonding in vehicles.
