Sikaflex®-255 FC is a 1-component elastic high-performance direct glazing adhesive with gap-filling capabilities that cures on exposure to atmospheric humidity and form a durable elastomer. Sikaflex® -255 FC is manufactured in accordance with ISO 9001/14001 Quality Assurance Systems and the Responsible Care Program.

Product Benefits

- One-component

- Low odor

- Bonds and seals at the same time

- Short tack free and curing time

- Very high thixotropy for good gap filling properties

- Adhesion to a wide range of substrates

- Non-staining curing process

- Non-corrosive

- Initial load bearing capacity

- Over paintable with many coatings (Consult Sika)

- Increases torsional stiffness of final assembly

- Shock/Impact resistant

- Vibration and sound damping properties

Areas of Application Sikaflex®

-255 FC is designed for direct glazing applications with mineral glass-based windows as well as bonding metal panels (primed and painted). Sikaflex® -255 FC offers extremely high initial bond strength. Its fast rate of cure results in rapid strength development and shorter service times.

- Bonding trim, molding and all kinds of styling elements

- Structural bonding of large parts, including sheet metal, composites and glass

- Used to replace rivets and other mechanical fasteners

- This product is suitable only for experienced professional users.

- Tests with actual substrates and conditions have to be performed to ensure adhesion and material

Chemical Resistance

Sikaflex®

-255 FC is resistant to fresh water, seawater, dilute acids and caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal oils; not resistant to organic acids, alcohol, concentrated mineral acids and caustic solutions or solvents. The above information is offered for general guidance only. Advice on specific applications will be given on request.

Method of Application

Surface preparation

Surfaces must be clean, dry and free from all traces of grease, oil and dust. The surfaces must be treated with a cleaning or activating agent and/or primed with the appropriate primer. S

Application

Cartridges: Pierce cartridge nozzle opening. Unipacs: Place unipac in the application gun and snip off the closure clip. Cut tip of nozzle to appropriate size. For satisfactory results the adhesive must be applied with a piston type manual, air or battery cartridge gun. To ensure uniform thickness of adhesive bead, we recommend that the adhesive is applied in the form of a triangular bead (see illustration). Do not apply below 50°F (10°C) or above 95°F (35°C). The optimum temperature for substrate and adhesive is between 59°F (15°C) and 77°F (25°C).
