Dry Adhesive (CDF Adhesive)

Characteristics:

Activation Required: Dry adhesive is non-sticky to the touch and requires activation with a slip solution during installation.

Chemical Bonding: Over time, it undergoes a chemical bonding process with the glass surface, which gradually reveals an underlying pressure-sensitive layer.

Benefits:

Ease of Installation: Its non-sticky nature before activation allows for easier handling and adjustment on large windows, making it especially useful for architectural applications where precision is key.

Contamination Resistance: Less prone to contamination because it can be easily rinsed and re-applied during the initial installation phase without compromising the adhesive's effectiveness.

Pressure Sensitive Adhesive (PS Adhesive)

Characteristics:

Immediate Bonding: Inherently sticky, it bonds instantly to surfaces upon contact, requiring no activation.

Versatility: Suitable for a wide range of applications, including automotive and architectural tinting, due to its strong, immediate adhesion.

Benefits.

Rapid Application: Ideal for quick installations, as it adheres firmly and quickly to the window surfaces without the need for a lengthy curing process.

Curved Surface Compatibility: The instant stickiness is particularly advantageous for curved or contoured windows common in automotive applications but can also benefit architectural projects with similar challenges.

Comparative Overview

While both adhesives are used in architectural window tinting, Dry Adhesive is often preferred for larger, flat glass surfaces where precision and the ability to manage contamination are priorities. Its delayed bonding process allows for adjustments during application, making it user-friendly and forgiving during the installation process.

Pressure Sensitive Adhesive, on the other hand, offers the advantage of instant adhesion, which can be beneficial in situations where quick application is necessary or for windows with complex shapes that require the film to bond immediately to avoid misalignment.

Ultimately, the choice between dry adhesive and pressure-sensitive adhesive depends on the specific requirements of the architectural window tint project, including the type of windows being tinted, the installer's preference for handling and application techniques, and the desired outcome in terms of appearance and performance.
