Autoshield NP-60 is a fast, one-component, moisture-curing polyurethane windscreen adhesive. It forms a high-modulus, flexible bond for professional replacement windscreens and suitable fixed automotive glass, including approved applications on aluminium-bodied vehicles.

Primerless ceramic-band bonding: NP-60 is applied without a separate primer to correctly prepared ceramic-band glass. Plain glass without a ceramic band requires Autoshield Activator followed by Autoshield GB Primer. Follow the different surface-preparation steps below and the relevant vehicle glazing procedure.

1-hour drive-away with dual airbags: NP-60 passes the FMVSS 212 windscreen-retention crash test after 1 hour at 23°C and 50% relative humidity. This published test result applies to those conditions; installers must establish the appropriate safe drive-away time for each completed vehicle installation.

Where to use NP-60

  • Windscreen replacement: bond compatible vehicle windscreens.
  • Fixed side glass: install suitable bonded side glazing.
  • Aluminium-bodied vehicles: use where the glazing system and vehicle manufacturer permit.

Glass preparation

  • Plain glass (no ceramic band): clean with Autoshield Activator using the stated wipe-on/wipe-off method. Apply a thin, even film of Autoshield GB Primer and allow 15–60 minutes drying time under the applicable conditions before bonding.
  • Ceramic-band glass: check the ceramic band's light transmission and clean off surface contamination. Lightly abrade the bond area using a Scotch-Brite Very Fine Red pad (the TDS specifies five back-and-forth movements). Finish with a single-pass wipe using an acetone-dampened, lint-free cloth; repeat if needed and do not touch the prepared area.

Application and limitations

Apply NP-60 in a continuous triangular bead and position and press the glass before the adhesive skins. Skin formation is approximately 20–35 minutes at 23°C and 50% relative humidity. Apply between 5°C and 35°C. The TDS requires longer drying times at 5–15°C; consult it for full instructions. Never clean old polyurethane sealant with an alcohol-containing solution. Avoid contact with cured or uncured silicone and incompatible hybrid sealants (MS, SPUR or STPE). Follow all product and vehicle-specific installation and safe drive-away requirements.

Is NP-60 primerless?
Yes. NP-60 can bond primerless to properly prepared ceramic-band glass. On plain glass without a ceramic band, use Autoshield Activator AP1001 and GB Primer as specified in the product preparation procedure.

What is the drive-away time?
NP-60 passes the stated FMVSS 212 dual-airbag test after one hour at 23°C and 50% relative humidity. The installer must confirm the safe drive-away time for the actual installation conditions.

What temperatures can NP-60 be applied at?
The stated application range is 5°C to 35°C; drying and curing times vary with conditions.

What should I avoid?
Do not clean old polyurethane bead material with alcohol or contaminate the bond with silicone or hybrid sealants.

High-modulus, moisture-curing polyurethane adhesive for compatible bonded windscreens and fixed automotive glass. Published FMVSS 212 windscreen-retention test performance includes a one-hour result with dual airbags under specified conditions at 23°C and 50% relative humidity; actual safe drive-away time must be determined for the vehicle and installation. Technical properties reported for NP-60 include elongation above 700% (ISO 37) and cured service-temperature resistance from -40°C to +90°C; consult the current TDS for the applicable limits and test methods.
NP-60 is primerless on correctly prepared ceramic-band glass. Check ceramic-band light transmission, clean contamination, and lightly abrade with Scotch-Brite Very Fine Red (five back-and-forth movements). Finish with a single pass using a lint-free cloth dampened with acetone; repeat if needed and do not touch the prepared area. For plain glass without a ceramic band, use Autoshield Activator by the specified wipe-on/wipe-off method (30–60 seconds after application), then apply a thin even film of Autoshield GB Primer. Allow the primer to dry 15–60 minutes under the specified conditions before bonding. Apply a continuous triangular NP-60 bead and press glass into place before the adhesive skins (approximately 20–35 minutes at 23°C and 50% RH). The application range is 5–35°C. At 5–15°C, double the drying times stated for at least 15°C. Do not clean old polyurethane sealant using alcohol. Avoid cured or uncured silicone and hybrid MS, SPUR and STPE sealants. The TDS records FMVSS 212 dual-airbag crash-test performance after one hour at 23°C and 50% RH. Confirm actual safe drive-away time for the specific vehicle and completed installation. Follow the July 2023 NP60 TDS and applicable vehicle repair requirements.
Do not clean old polyurethane adhesive with alcohol-containing products because alcohol inhibits cure. Do not apply in the presence of cured or uncured silicone or hybrid sealants such as MS, SPUR or STPE. Do not apply below 5°C. Between 5°C and 15°C, double normal drying and primer cure times. Store the pack around 20°C before cold-weather use. Keep Autoshield Activator closed when not in use and do not use it if cloudy.
  • Prepared ceramic-band automotive glass.
  • Compatible vehicle body apertures, including aluminium bodywork.
  • Fixed side glass and bonded vehicle glazing systems.

Adheseal NP-60 Polyurethane Windscreen Adhesive - Use Cases

Here are some common examples on where Adheseal NP-60 Polyurethane Windscreen Adhesive used by our customers.

Auto Body

Structural Vehicle Glass Bonding

Direct glazing vehicle glass, especially on modern lightweight or aluminium body structures.

Its high modulus and flexible bond contribute structural rigidity and maintain integrity under vehicle movement.

  • Aluminium bodies compatible
  • High modulus ~6 MPa
  • >700% elongation
  • None sagging (ISO 7390)

Auto Body

Fast professional windscreen replacement

Windscreen replacement where an approved polyurethane glazing system and verified safe drive-away procedure are required.

NP-60 has published FMVSS 212 windscreen-retention test performance with dual airbags under specified conditions. The one-hour test result is not an unconditional safe drive-away time for every vehicle or installation.

  • Published FMVSS 212 test result under specified conditions
  • High initial holding strength
  • One-part moisture-curing polyurethane

Auto Body

Direct glazing windscreen bonding

Professional bonded windscreen replacement where substrate preparation and a suitable vehicle-specific safe drive-away time can be established.

NP-60 offers high initial holding strength and a resilient polyurethane bond for compatible automotive glazing. Its published one-hour FMVSS 212 result applies only under specified test conditions, not universally to each repair.

  • FMVSS 212 test performance is conditional
  • High-modulus polyurethane
  • Surface preparation depends on glazing substrate

Auto Body

Automotive Side Glass Bonding

Bonding fixed side or rear glass panels in vehicles where high initial strength and quick setting are critical for assembly.

Its rapid skin formation and high green strength secure glass quickly, allowing efficient assembly processes and minimising glass displacement before full cure.

  • 20-35 min skin forming
  • High green strength
  • 3 mm / 24 hr cure time
  • Applicable for aluminium bodies

Auto Glass

Structural bonding for vehicle windscreens and fixed glass

Installing new or replacement windscreens and side glass into automotive bodywork, including aluminium, where consistent, high-strength adhesion is critical for vehicle safety and long-term performance.

This high-modulus polyurethane adhesive is intended for compatible windscreens and fixed automotive glass. Preparation products and procedures must be selected for the glass, body aperture and vehicle repair specification; do not assume both Activator and GB Primer are always required.

  • High modulus (approx. 6 MPa at break)
  • Elongation at break >700%
  • Temperature resistance -40 °C to 90 °C
  • Suitable for aluminium bodies
