BOLL Windscreen Installation Kit

BOLL Windscreen Installation Kit SPRINT contains the adhesive, primer and essential accessories required for removing and installing bonded automotive glass.

BOLL Windscreen Adhesive SPRINT is a one-component polyurethane adhesive that cures rapidly through contact with moisture in the air to form a durable elastomeric bond.

It offers strong mechanical performance and resistance to water, weathering and acids.

The flexible cured bond accommodates the different thermal expansion rates of glass and metal, allowing the bonded surfaces to move independently during temperature changes.

Designed for bonding front windscreens and rear vehicle windows. Suitable for vehicles fitted with airbags.

The adhesive complies with the FMVSS 212 crash-test standard after 3 hours at 23°C and 50% relative humidity.

METHOD OF USE

Clean and degrease the edges of the glass with BOLL Silicone Remover.

Apply BOLL Glass Primer to the glass and vehicle body bonding surfaces using the supplied applicator. Allow the primer to dry for at least 15 minutes.

Apply a continuous bead of adhesive to the body flange using a manual or pneumatic BOLL caulking gun. Position the windscreen, press it lightly against the flange and secure it using the supplied spacer blocks.

At 23°C and 50% relative humidity, the manufacturer states that the vehicle can be driven after 1 hour. Compliance with the FMVSS 212 crash-test standard is achieved after 3 hours under the same conditions.

APPLICATION

1. Clean and degrease the edges of the glass using BOLL Silicone Remover.

2. Prime the glass and vehicle body bonding surfaces with BOLL Glass Primer.

3. Allow the primer to dry completely for approximately 15 minutes.

4. Apply the adhesive using a BOLL caulking gun.

5. Position and press the windscreen firmly onto the spacer blocks.

6. Allow approximately 1 hour at 20°C before using the vehicle.
