Description  

Autoshield GB Autoglass Primer is a black automotive glazing primer used to prepare compatible glass and vehicle bond surfaces for polyurethane windscreen adhesive. Its opaque film helps shield exposed polyurethane bond lines from UV and is used in suitable pinchweld repair details.

Choose GB Primer when the glazing system specifically requires a black primer or UV blockout layer. It is distinct from Autoshield Activator, a clear surface-treatment wipe. Neither product replaces the adhesive itself or a complete approved windscreen replacement procedure.

Typical uses

  • Plain-glass windscreen bonding: providing the specified black bond-line preparation where the glass lacks a suitable ceramic band.
  • Pinchweld repair details: treating appropriate scratches or chips in the prepared vehicle bond area, subject to the vehicle repair procedure.
  • Polyurethane autoglass systems: promoting adhesion at compatible glazing interfaces after the designated cleaning and activation steps.

Application and compatibility

Work on clean, dry, grease-free substrates and apply a thin, continuous film with a suitable applicator. Follow the adhesive system's exact flash-off and overcoating requirements. With Autoshield NP-60, the associated installation instructions specify a 15–60 minute primer drying window, with additional allowance in colder conditions.

This is a solvent-containing professional glazing preparation product. Avoid incompatible plastics and uncured films; keep the container sealed and use appropriate ventilation and PPE. Vehicle glazing performance and safe drive-away depend on the entire approved system and installation conditions.

Common Questions  

What is Autoshield GB Primer used for?
It primes automotive glass and compatible body bond surfaces before Autoshield 1-FC polyurethane adhesive.

How long should it flash off?
Allow at least about 10 minutes above 5°C and follow the current TDS for the permitted maximum open time.

What coverage should I allow?
About 50ml/m².

Why is the primer fluorescent?
The luminescent agent helps installers check primer coverage under long-wave UV light.

Uses & Benefits  
Black solvent-based polyurethane primer for direct automotive glazing with Adheseal Autoshield 1-FC. Promotes adhesion and provides UV blockout at the bond line. Contains a luminescent agent that assists coverage checking under long-wave UV light. Application temperature is 5°C to 40°C. Coverage is about 50ml/m² and flash-off is at least about 10 minutes above 5°C before adhesive installation.
How To Apply  
Prepare glass and body bond faces so they are dry and free from oil, grease, dust and contamination. Shake or mix the primer as required by the current TDS before use. Apply a thin continuous coat by brush, felt or foam applicator at about 50ml/m². Allow the required flash-off, at least about 10 minutes above 5°C. Check coverage where required using the primer's long-wave UV fluorescence, then apply Autoshield 1-FC within the permitted open time.
Limitations and Safety Info  
Use only on clean, dry and properly prepared glazing and vehicle-body bond surfaces. Do not apply outside the 5°C to 40°C application range. Do not leave the primed surface exposed to contamination before adhesive application. Follow the current TDS for the maximum open period after priming. Use the current SDS for solvent and flammability controls.
Suitable Substrates  
  • Automotive float glass.
  • Ceramic-coated automotive glass.
  • Prepared painted and pre-coated vehicle body surfaces.
  • Compatible prepared metals and plastics used in direct glazing systems.
