Overview
When securing windows to the metal frames of truck cabs, one of the following methods are employed:

• Mechanical gasketing with a rubber grommet
• Bonding or "glazing" with an elastomeric adhesive

Benefits
Teroson® Terostat™ moisture curing urethanes, with the assistance of primers, are typically used for window glazing and offer the following advantages over mechanical gasketing:

• Airtight seal, resulting in improved noise, vibration, and harshness enhancements
• Higher strength, leading to increased glass retention
• More automated assembly process, reducing labor costs
• FMVSS Certified for drive away time

Loctite's primerless window glazing solution saves you money by:

• Eliminating the cost of primers
• Eliminating VOCs associated with primers
• Removing the time spent on primer application
• Reducing complexity in the manufacturing 

A viable alternative to utilizing a urethane for window glazing is the use of a Teroson Terostat modified silane (MS) based adhesive. In addition to providing all of the aforementioned advantages over mechanical gasketing, using MS adhesives provides additional benefits over urethanes for the assembler:

• No primer is required, improving output and product consistency
• Heated lines used for glazing grade urethanes are not required, saving capital cost for the manufacturer
