A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. Commonly used agents are insoluble oils, polydimethylsiloxanes and other silicones, certain alcohols, stearates and glycols. The additive is used to prevent formation of foam or is added to break a foam already formed. We can make a distinction between macro- and micro-foam. Macro-foam is often formed at the surface of the coating and micro-foam is entrapment of air bubbles what is not able to rise fast enough to the surface. For micro foam you need a so-called air release agent to coagulate the micro bubbles to bugger air bubbles so they can rise faster to the surface to be destroyed. In industrial processes, foams pose serious problems. They cause defects on surface coatings. They prevent the efficient filling of containers. A variety of chemical formulae are available to prevent formation of foams. Properties: Generally a defoamer is insoluble in the foaming medium and has surface active properties. An essential feature of a defoamer product is a low viscosity and a facility to spread rapidly on foamy surfaces. It has affinity to the air-liquid surface where it destabilizes the foam lamellas. This causes rupture of the air bubbles and breakdown of surface foam. Entrapped air bubbles are agglomerated, and the larger bubbles rise to the surface of the bulk liquid more quickly.

UNIQ®FOAM

UNIQ®FOAM® LP2507 is a strong defoamer/anti-foam based on organic polymers, this product can be used for grinding and spraying conditions. Working well against macro-foam, but delivers also strong micro-foam destroying properties. It is well suited for all water based systems and pigment concentrates.

UNIQ®FOAM® LP2507

UNIQ®FOAM® 180W is a silicone-free surface additive for aqueous coatings to prevent surface defects such as cratering, scarring, bubbles, pinholes, orange peel and boiling marks and to improve leveling.

UNIQ®FOAM® 180W

UNIQ®FOAM® 132S is medium to strong defoamer to be used in clear coatings as well suitable for pigmented coating systems. Due the chemical structure the product will not cause turbidity, but will give good air-release and macro defoaming properties. Also very well suited for PE primers remaining high clarity and transparency. The product is well suited for spraying applications.

UNIQ®FOAM® 132S

UNIQ®FOAM® 150S is a strong defoamer can be used for all solvent borne coating systems, especially suitable for solvent free epoxy and solvent free UV system. The additive has an immediate foam-destroying effect with very strong deaeration and does not have influence on the intercoat adhesion. With epoxy resin the defoamer can give slight haziness, but as soon the hardener is added the products becomes fully clear. Therefore the product is suited for pigmented and non pigmented systems.

UNIQ®FOAM® 150S

UNIQ®FOAM® 175S is especially effective in wood and furniture coatings based on glossy polyester, paraffin polyester, and in radiation curable polyester. The additive allows curtain coaters to maintain curtain stability even when only thin layers are applied. When using non-pigmented systems, a slight turbidity may be visible over dark wood. Good results were also found with epoxy systems.

UNIQ®FOAM® 175S

UNIQ®FOAM® 120S is a strong defoamer suitable for all solvent borne coating systems. It prevents the formation of foam during the manufacture and filling. The additive has an immediate foam-destroying effect and does not have influence on the intercoat adhesion. Due to the strong defoaming performances, the product is less suitable for high gloss clear coatings. Influence of transparency in clear systems should be evaluated.

UNIQ®FOAM® 120S

UNIQ®FOAM® 152S is a strong silicone free defoamer can be used for all solvent borne coating systems, especially suitable for solvent free self-leveling epoxy system. The additive has excellent defoaming and strong de-aeration, and not influence on the intercoat adhesion. At the same time, it will improve the leveling properties and give excellent film appearance in high gloss systems and will give good compatibility.

UNIQ®FOAM® 152S

UNIQ®FOAM® 130S is very strong defoamer based on acrylic polymer (polyvinyl ether), showing superior de-aerating effects. Suitable for all solvent based paints, to be used in various thermo-setting- and air-drying paints. Applications include architectural paints, floor coats, heavy duty paints, auto-refinishes, coil coatings and car OEM.

UNIQ®FOAM® 130S

UNIQ®FOAM® 170S is a strong anti-foam and air-release agent especially suitable for use in unsaturated polyesters, baking coatings, epoxies and acrylic/vinyl acetate combinations. The additive furthermore helps to improve the leveling.
