Two new BYK additives ring in the year 2021

BYK-329, a silicone-containing surface additive for both solvent-free and solvent-borne systems, is the new BYK product on the market that greatly reduces surface tension, especially in floor coatings and general industrial coatings, and promotes leveling and defoaming properties. In the defoamer line, BYK-092 is a new VOC-free, silicone-containing additive for aqueous paint systems, printing inks, and adhesives in the portfolio of this specialty chemicals manufacturer.

BYK defoamer for a particularly wide range of applications

BYK-092 is a highly effective defoamer for aqueous systems, especially for clear coats and high gloss systems. Yet it can also be used to excellent effect in matted and pigmented systems. Thanks to its balanced compatibility, this product affects neither transparency nor gloss. BYK-092 is effective not only in all of the customary applications, but also in difficult applications such as HVLP and roller coatings. This additive can be introduced at any time during production.

This new BYK product is likewise recommended for defoaming printing inks and overprint varnishes, and can even counteract microfoaming. Neither the transparency nor the gloss is affected.

Furthermore, BYK-092 is also suitable for defoaming adhesives and sealants. Its strong defoaming effects and its long shelf life are only two factors here that make this new product ideal for adhesives.

User-friendly surface additive

BYK-329 greatly reduces the surface tension in coating systems, thus promoting their leveling and defoaming properties. The product profile is rounded off by enhanced substrate wetting, specifically in two-pack epoxy resin systems for floor coatings.

This new BYK additive is suitable for both solvent-free and solvent-borne two-pack epoxy resin, polyurethane, and polyaspartic coatings. Even small added quantities serve to enhance the leveling and defoaming properties.

About BYK

BYK is one of the world’s leading suppliers in the field of additives and measuring instruments. Additives are chemical substances which, when used in small quantities, improve product properties such as scratch resistance or surface gloss. Manufacturing processes are also optimized by the addition of additives.


The coatings, inks, and plastics industries are among the main consumers of BYK additives. Yet with the production of oil and gas, the manufacture of care products, the production of adhesives and sealants, and construction chemistry, too, BYK additives improve the product characteristics and production processes. Testing and measuring instruments from BYK can effectively evaluate the quality of color, gloss, and appearance as well as the physical properties of paint, plastic, and paper products and are an important part of quality control.


As a globally operating specialty chemicals company, BYK has production sites in Wesel, Kempen, Moosburg, Schkopau and Geretsried (Germany), Deventer, Denekamp and Nijverdal (Netherlands), Widnes (UK), Wallingford, Chester, Gonzales, Louisville, Rochester Hills, Earth City (USA) and Tongling (China).


Today the company employs around 2,300 people worldwide and forms part of the ALTANA Group.
