3M Auto Glass Urethane Windshield Adhesive 10.5 fl oz Cartridge — Black, Fast‑Curing High‑Strength Sealant

3M Auto Glass Urethane Windshield Adhesive (08693) is a black, medium‑viscosity urethane formulated to permanently bond windshields and fixed auto glass using a standard caulking gun.

This cartridge contains 10.5 fluid ounces of a non‑sag, fast‑curing urethane designed for professional automotive glass installation and repair. It delivers high bond strength for stationary glass attachment and is compatible with manual or powered caulking guns. Intended for industrial and occupational use, the adhesive balances workability with a cure profile that reaches handling strength quickly while forming a durable structural seal.

How quickly does this adhesive set and return a vehicle to service?

The formula is engineered to cure rapidly compared with traditional mastics, typically achieving handling strength within a short period and full cure in approximately 24 hours under typical conditions. Actual cure time varies with temperature, humidity and joint thickness, so technicians should follow job‑site environmental best practices.

• Typical full cure: ~24 hours under standard shop conditions
• Faster handling at warmer temperatures and higher humidity
• Follow OEM and glass manufacturer recommendations for safe drive‑away time

Will this work with my caulking or pneumatic dispensing equipment?

Yes — the 10.5 fl oz cartridge is compatible with both manual and powered caulking guns, allowing installers to use their preferred dispensing method. The medium viscosity gives controlled bead formation and resists sagging on vertical or overhead joints.

• Fits standard 10.5 fl oz caulk guns and pneumatic applicators
• Medium viscosity for precise bead control and reduced waste
• Non‑sag formula for clean application on vertical seams

Is this product suitable for all automotive glass jobs?

This urethane is formulated for permanent windshield bonding and other stationary glass attachments in automotive and heavy‑duty applications. While versatile, installers should confirm compatibility with the vehicle manufacturer, glass type, primer requirements and any specific OEM adhesion protocols.

• Designed for windshield and fixed glass bonding
• High bond strength appropriate for most auto glass installations
• Check for required primers or surface prep per OEM specs

What are the handling and safety considerations?

Intended for trained professionals and occupational settings, this adhesive should be used with appropriate protective equipment and ventilation. Dispose of cartridges and waste in accordance with local regulations and follow 3M safety data sheet recommendations for storage and use.

• For industrial/occupational use only, not a consumer product
• Use PPE and ensure adequate ventilation during application
• Refer to 3M SDS for first aid, storage and disposal information

Who is this for? Professional auto glass installers, collision repair shops and fleet service centers that require a reliable, high‑strength urethane for permanent windshield and stationary glass bonding will benefit most from this product. It suits technicians who need a cartridge format compatible with common dispensing tools and a medium‑viscosity adhesive that balances ease of application with strong, durable bonding performance.
