Products in Additives: Defoamer

Efka® PB 2010 is a highly efficient defoamer designed for solvent-based coatings, particularly high-gloss top coats. Its universal nature allows its use for semi-matte and matte coats with a wide range of solvent-based binders. Silicone-free, it has no negative impact on inter-coat adhesion, making it suitable for primers, sealers, and various solvent-based systems, providing high defoaming performance while maintaining excellent compatibility.

Efka® PB 2001 is a silicone-free defoamer tailored for non-aqueous coatings. It is especially suited for highly viscous coatings based on 2-pack epoxy, unsaturated polyester, and PUR systems. The blend of vinyl polymers in organic solvents ensures effective defoaming, making it suitable for applications like nitrocellulose lacquers, acid-curable wood coatings, and fast-drying formulations applied on curtain coaters.

Efka® PB 2020 is a defoamer that accelerates defoaming in solvent-based coatings. It eliminates foaming and blistering caused by various factors, such as wood or paper substrates or during pumping, rolling, flooding, or airless spraying. This defoamer is particularly suitable for nitrocellulose lacquers, acid-curable wood finishes, two-pack polyurethane lacquers, and cold-cured epoxy resin systems.

Efka® SI 2723 acts as a defoamer, developed for the rapid de-aeration of solvent-free polyurethane and epoxy compounds. It yields excellent results in flooring applications, ensuring foam- and blister-free self-leveling coatings. Additionally, it acts as a leveling agent, contributing to a smooth coating surface, all while maintaining a low odor. Its chemical nature consists of a solution of defoaming substances containing silicone.

Efka® PB 2770 is an innovative, silicone-free, 100% active defoamer specifically designed for radiation curing systems. It excels at foam breakdown and exhibits exceptional compatibility. Efka® PB 2770 functions effectively as a deaerator and defoamer, making it suitable for a wide range of applications, including clear and pigmented UV-curable formulations, composites, gel coats, cast resins, and adhesives.

Efka® PB 2744 serves as a defoamer and de-aerator, specifically developed for fast and effective de-aeration in high solid and solvent-free formulations (e.g., 2-pack PUR compounds for flooring applications). It exhibits excellent efficiency, improves leveling, and imparts surface smoothness, with a focus on excellent long-term persistency.

Efka® PB 2720 is a defoamer with key benefits including supporting quick de-aeration of thermosetting resin systems and allowing easy processing of foam and blister-free self-leveling compounds and laminates. It is a solution of defoaming substances, silicone-free, and can be used in pigmented or non-pigmented resin systems, such as unsaturated polyesters (SMC/BMC gelcoats and synthetic mortars), two-pack epoxies, and PVC compounds.

AFCONA 7202 is mainly recommended for UPE resin systems. It is considered to be a moderately strong defoamer, so it is not suitable for unpigmented or clear systems. Adding AFCONA - 7202 to resin may result in in-can haziness, but this will have a minimal effect on the final gloss and will not affect the other properties of the system.
