What is the risk of improper moisture management during adhesive curing?

• A. Poor bond strength, gap formation, and potential leak or wind intrusion.
• B. Faster curing
• C. No effect
• D. Improved adhesion

Answer: (A)

Moisture-driven curing means the adhesive relies on ambient moisture to set properly, so controlling moisture is crucial. When moisture isn’t managed correctly, the cure can become uneven, trapping moisture or creating bubbles and a compromised polymer network. This weakens the bond to the glass and vehicle surface and often leaves micro-gaps at the bond line. Those gaps can permit water and air to penetrate, leading to leaks and wind intrusion under pressure. So the main risk is a weaker bond with potential sealing failures. Faster curing, no effect, or improved adhesion aren’t accurate here because they don’t describe the common problems seen when moisture isn’t properly controlled.
