Specialised Vehicles
Direct Glazing and Sealing

For over 20 years, Sika has been providing specialised vehicles, bus and coach, automotive, truck and rail OEM assembly lines with adhesive and sealant solutions for sealing and direct glazing. Primerless, manual and automated pre-treatment options are available to fit the needs of a variety of OEM application processes in order to create significant cost savings and manufacturing process simplification.

Sika offers a wide range of adhesive and sealant technologies to suit all direct glazing and sealing applications. Specific Sikaflex solutions are available to suit cold, warm and hot application processes. Proprietary Sikaflex? materials are capable of retaining the glass in position following installation, allowing for elimination of secondary clips, fixings and tape. Sikaflex materials can also provide low electrically conductive properties for elimination of galvanic corrosion. The SikaTack?-Plus Booster range provides the ultimate solution for OEM’s seeking excellent mechanical properties with the shortest possible full cure time. Unlike traditional two-component systems, this boosted one-component system has the significant benefit of full material cure irrespective of the presence of the accelerator paste, providing enhanced process/quality consistency and security. Sikaflex PUR-Hybrid technology (STP-technology) combines the performance of traditional Sikaflex polyurethane systems, but shows additional characteristics such as reduced substrate surface preparation and improved ecological benefits.

Why Direct Glaze?
   
- Increased body stiffness for enhanced roll-over strength and improved occupant impact protection
- Higher body stiffness to reduce noise, vibration and harshness within the vehicle body
  
Why Seal?
   
- Improved acoustic environment (lower noise)
- Watertight seals ensure protection of vital electronic equipment
- More efficient air-conditioning and heating
- Watertight seals ensure durable and long-lasting protection
  
Technological Benefits
   
- Sika’s tried and tested primerless to glass technology
- Primerless to paint
- Accelerated with Sika® Booster for rapid full cure
- High initial green strength
- Hot and warm applied systems to eliminate secondary clips, fixings and tape
- Elimination of water intrusion and leakage
- Simple substrate preparation, very easy to use
- High levels of aesthetic finish achievable
- Excellent resistance to harsh climatic conditions
