Products:20

FoamStar® products are used as defoamers. BTC’s FoamStar® defoamers suppress and destroy foam and its negative effects during inks and printing applications. By removing or inhibiting air bubbles they are important process aids throughout the production as well as the applications process. Manufacturers benefit from foam-free production processes by reaching their desired results much quicker.

Labeling Claims:VOC-free

FoamStar® ED 2523 is an emulsion defoamer, a universal polymer-emulsion defoamer enhanced with a small amount of modified polydimethylsiloxane (PDMS). It is an excellent defoamer for many flat to semi-gloss aqueous coatings, providing excellent foam suppression during grinding as well as application. It retains antifoam efficiency during extended storage of paint.

FoamStar® SI 2240

Chemical Family:Siloxanes
End Uses:Waterborne Coating
Labeling Claims:Food Contact Acceptable, APEO-free

FoamStar® SI 2240 is a defoamer designed for pigment concentrates, pigmented aqueous coatings, printing inks, and adhesives. It exhibits a spontaneous defoaming effect, good compatibility, and high efficiency. With broad food contact compliance, it maintains excellent stability under high shear conditions, such as during grinding. The chemical nature involves a compound of modified polydimethylsiloxanes.

FoamStar® SI 2292

Chemical Family:Siloxanes
Compatible Polymers & Resins:Polyurethanes (PU), Acrylics

FoamStar® SI 2292 is a defoamer and de-aerating agent suitable for aqueous coatings and coatings containing co-solvents. It is especially effective for wood coatings, highly compatible, and consists of a blend of specially modified polydimethyl siloxane. It is recommended for emulsion paints based on pure acrylates and acrylic copolymers, as well as for wood coatings based on acrylates and polyurethane emulsions.

FoamStar® SI 2293

Chemical Family:Siloxanes
End Uses:Clearcoat
Compatible Polymers & Resins:Polyvinyl Chloride (PVC), Polyurethanes (PU), Acrylics
Labeling Claims:Non-Hazardous, VOC-free

FoamStar® SI 2293 is an excellent defoamer designed for high-quality emulsion paints based on pure acrylates and acrylic copolymers. It is recommended for wood coatings based on acrylic and polyurethane emulsions applied by various methods. The defoamer is effective in emulsion and suspension polymerization during the manufacture of polyvinyl chloride, vinyl acetate, and acrylic emulsions.

FoamStar® ST 2400

Compatible Polymers & Resins:Acrylics

FoamStar® ST 2400 is part of a novel series of defoamers based on patented FoamStar® technology. It offers a very fast bubble break compared to conventional defoamers, proving effective in industrial coatings based on acrylic emulsions, with good persistence. The chemical nature involves a defoamer based on patented FoamStar® technology and mineral oil.

FoamStar® ST 2438

Chemical Family:Siloxanes
