Overcoming a major anti-fogging challenge Longevity
While anti-fog surfactants and additives have been around since the 1960s, their longevity concerns have persisted up to now. Numerous additives promise anti-fog performance by migrating to the plastic surface, only to be washed away during use.
The result? Plastics and films lose their anti-fog, drip and misting properties well before the intended product lifetime ends, meaning products underperform and require replacement or the application of an additional anti-fogging solution. In challenging use conditions, the performance of these anti-fog products diminishes within months and cannot withstand continuous washing or abrasion.
The application of additional anti-fogging solutions, such as coatings is often used to regenerate anti-fogging performance, but this solution also suffers from robustness issues and still doesn’t provide permanent anti-fogging action. Abrasion resistance and handling of the film can reduce anti-fog effectiveness considerably over short periods of time.
