Capstone® fluorosurfactants are multifunctional in paints and coatings, especially when formulated with low- or no-VOC products. Benefits include wetting (improved intercoat adhesion, and the ability to wet out low energy surfacts), leveling (improved gloss, and reduced “orange peel,” or decreased incidence of Benard cells), antiblocking (the tendency of glossy paints to stick to themselves), and the ability to reduce cratering, an effect due to the presence of surface imperfections or contaminants.

Ink and Graphics Arts
DuPont™ Capstone® fluorosurfactants give excellent wetting and leveling properties for these types of coatings, without interfering with the dispersed phase dyes and pigments. Further, since the Capstone® fluorosurfactants tend to rise to the air interface, they can reduce “transfer’ to the next surface when sheet or roll-type products are stacked.

Product Functions:
• Anti-block
• Accept Ink
• Leveling
• Wetting
Adhesives, Sealants, Caulks
Adhesive applications exist in many forms, such as adhesives for tape, for hot-melt, for wood (and other porous surfaces). Adhesives are used in packaging, construction, and many OEM applications. In general, the addition of a small amount of Capstone® improves wetting and penetration of the adhesive into the pore structure of the items to be joined, strengthening the bond.

Product Functions:
• Wetting
• Reduced surface defects
• Dynamic surface tension reduction
• Penetration of adhesive
Films
Surface energy of the film is increased by ionization, flame treatment, or the film contains some manner of “roughener” to improve adhesion of subsequent coatings.
Print Acceptors — DuPont™ Capstone® improves wetting and leveling of coatings for ink, improving adhesion, abrasion resistance, reducing transfer, and general “printability.”
Anti-Stats — Capstone® can provide anti-static properties in a variety of coating applications.
UV-Curable Coatings — Several Capstone® Intermediates will “lift and lock” in UV systems.
Re-Wet — Capstone® comes to the top of a coating, and encourages wetting in multi-coat operations.
Release Coatings — There are basically two types of films: CAST (the polymer is dissolved in some manner of solvent, cast on a belt or drum, and the solvent is driven off, and often, recovered), and EXTRUDED (melted resin is pushed through a die). Because Capstone® fluorosurfactants seek the liquid-air interface in coatings, Capstone® can impart release characteristics to that coating. Can be similar to applications noted in UV curable systems.

Although there are many types of films, the function of Capstone® is quite similar in all:
• Anti-block characteristics for roll products
• Anti-static properties
• Improved surface properties
• Most films are post-treated to accept coatings
• Leveling of the film, giving even thickness
• Reduction of cratering caused by the presence of impurities
• Release — getting the film to come off the belt/drum without deformation, tearing, or edge effects
• Water repellency
• Wetting
