What role does glass cleaner play in the urethane application process?

Glass cleaner plays a significant role in the urethane application process primarily by assisting in degreasing the surface. Before applying urethane, it is essential to ensure that the area is clean and free of contaminants like dirt, grease, or residues that could interfere with adhesion. Glass cleaner effectively removes these contaminants, allowing for a good bond between the urethane and the surface of the glass.

When surfaces are not properly cleaned, impurities can compromise the integrity of the adhesive bond, resulting in potential leaks or failure of the seal over time. By properly degreasing the surface with glass cleaner, the application of urethane is more likely to succeed, ensuring a proper and durable installation.

The other choices, while they may relate to the general application of urethane, do not specifically address the function of glass cleaner within this context. For instance, urtherane curing time, preventing leaks, and enhancing bond strength rely more on the properties of the urethane itself rather than the cleaning agent used.
