A general overview based on the manufacturer’s guidance. Always follow the technical data sheet and the vehicle manufacturer’s instructions.

  1. Clean the surfaces

    The glass and body paint must be dry and free of oil, dust and grease. Clean new glass and the paint coat with the recommended cleaner and check that the bonding surfaces are intact.

  2. Apply primer

    Apply the primer that suits your substrate with a primer applicator, and start gluing only after it has evaporated and dried.

  3. Lay the bead

    Use a pneumatic or electric glue gun. For the adhesive, form a triangular bead so the bond line has an even thickness. Work at 20–30 °C and 50–70% relative humidity if you can.

  4. Set the glass

    Position the glass while the adhesive is still open. Do not assemble once the adhesive has gone tack-free. Open time is much shorter in heat and high humidity.

  5. Let it cure

    Both products cure with moisture, and cure more slowly in the cold. Keep the adhesive away from chemicals that contain hydroxyl or amino groups, which can stop it curing.

Windshield sealant questions

What is auto windshield sealant?

Auto windshield sealant, also called windshield adhesive or urethane, is a polyurethane compound used to bond or seal automotive glass to the vehicle body and keep out water and air.

What is the difference between windshield adhesive and windshield sealant?

A windshield adhesive is used to assemble and bond the glass. A windshield sealant is used for caulking and sealing the windshield and resists the flow of black water.

Can I use silicone instead of windshield adhesive?

No. Windshield bonding relies on polyurethane products made for the job. General-purpose silicone is not a substitute.

How should windshield adhesive be stored?

Store in a cool, dry place at 5 to 25 °C. Shelf life is 9 months for the adhesive and 6 months for the sealant under these conditions, and shorter at higher temperatures. Reseal unused cartridges immediately.

How long until the vehicle can be driven?

Cure time depends on temperature, humidity and bead size. Both products are moisture-curing and cure more slowly in the cold. Follow the technical data sheet and the vehicle manufacturer’s instructions.

Which countries do you ship to?

We ship to South Korea, Russia and Europe. Ask us about other destinations.

How long does delivery take?

Do you offer ODM and custom packaging?

Yes. ODM and custom packaging are available on request. Send us your requirements, and we will confirm the details in your quotation.

Can you supply other automotive adhesives?

Yes. Besides windshield products, we can source Huitian’s other automotive adhesives, such as assembly adhesives, glue for car parts and aftermarket products. Tell us the application and we will confirm what is available.

Do you offer samples and technical data sheets?

Yes. Contact us for technical data sheets, safety data sheets, samples and packaging information.
