Silquest Wetlink 78 silane provides shelf stable non-yellowing adhesion promoter performance while enhancing physical properties in latexes and waterborne adhesive and sealant systems. When Silquest Wetlink 78 silane is incorporated as a crosslinker or adhesion promoter, it provides improved water resistance and wet adhesion, with good shelf stability.

Key Features and Benefits

• Excellent wet and dry adhesion, without yellowing
• Enhances tensile strength, while maintaining elongation performance
• Improves tear strength and durability
• Performance consistency with aging
• Improves water resistance of cured material

Potential Applications

Silquest Wetlink 78 silanes are excellent candidates for formulations employing carboxylated latexes (acrylic, SBR polyurethane, etc.) exhibiting a pH between 6 and 8.5.

Silquest Wetlink 78 silane can be employed as an adhesion promoter or crosslinker. It may be suitable for use as a water stable single component crosslinker in applications such as:

• Automotive laminate adhesives
• Furniture laminate adhesives
• Flocking adhesives

In such applications, Silquest Wetlink 78 silane should provide a means of replacing a 2 part waterborne adhesive with a single component system. The benefits of a silane crosslinked water stable single component system include reduced scrap, improved process efficiency and reduced crosslinker toxicity.

As an adhesion promoter for waterborne systems such as the acrylic sealant featured ar right, Silquest Wetlink 78 silane offers consistent and dramatic improvements in water stable adhesion performance.
