258 is a primerless to windscreen, one-component direct glazing adhesive. It is easy to apply and has a paste-like consistency. On exposure to atmospheric moisture it cures to a durable elastomer. SikaTitan® -258 provides a long tack-free time and ensures a safe application even under warm conditions. Note: Primerless application requires the glass to be prepared with a non-antistatic glass cleaner.
Also the bonding surfaces must be free of contamination prior to the application of the adhesive. SikaTitan® -258 is manufactured in accordance with ISO 9001 / 14001 quality assurance system and with the responsible care program.

Chemical Resistance
SikaTitan® -258 is resistant to fresh water, seawater, limewater, sewage effluent, diluted acids and caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils; not resistant to organic acids and caustic solutions or solvents.

Method of Application
Removal of old glass
Remove damaged glass in accordance with the vehicle manufacturer’s instructions.

Surface preparation
Surfaces must be clean, dry and free from dust and grease. The bond faces must be prepared with a non-antistatic glass cleaner.
Bonding surface must be free of contaminants before application of the product. Windshields without ceramic coatings need additional UV protection.

Cut off the tip of the nozzle in accordance with the vehicle manufacturer's recommendations and screw onto the cartridge. It is recommended to apply the adhesive with a piston-type application gun. To ensure a uniform thickness of adhesive bead, we recommend that the adhesive be applied in the form of a triangular bead (see fig. 1 below).
The substrate temperature must be between 5°C and 35°C.
