Add-Additives Company Logo
ADD-2720 is a silicone-free anti-foam that supports the quick de-aeration of thermosetting resin systems so that foam and blister-free self leveling compounds and laminates can be processed. ADD-2720 demonstrates no negative influence on inter-coat adhesion when overcoated. Additionally, it acts as an air release and leveling additive. It is designed for use in coatings, printing inks and composite. If used in conjunction with ADD-5044 or ADD-5066 in pigmented compounds, lower viscosity results can be achieved, thereby aiding the air release properties.

Applications & Uses

Coatings:
ADD-2720 can be used in pigmented and non-pigmented systems such as:
• Unsaturated polyesters
• Two-pack epoxies
• Epoxy floorings
• Acrylic/vinylacetate-combinations
• Oil-free polyesters
When combined with the silicone-based surface additive ADD-3239, which shows anti-foam action, slip performance can be observed. It should be incorporated by simple mixing. A homogeneous mix will increase the efficiency of ADD-2720.
0.1-1.0% on total formulation weight
Printing Inks:
ADD-2720 has been developed for solvent-based formulations and can be used in solventbased pigment bases and printing inks and over-print varnishes. It reduces the foam accumulation of
foam in the ink pan and reservoir during the printing process.
ADD-2720 is also suited for UV-curing formulations. It may be used in screen, gravure and flexographic printing inks.
ADD-2720 can be added in the premix stage prior to dispersion. If added post manufacture or press-side, care should be taken to ensure uniform distribution.

Storage & Handling

STORAGE, SAFETY & HANDLING

ADD-2720 should be stored in a cool dry place. When kept in an original unopened container, it will keep up to 5 years from the date of manufacture. ADD-2720 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet.
