BYK has an established history of innovation such as being the first additive manufacturer to begin using Controlled Polymerization Technology (CPT), launching the first rheology-modified wax emulsion, and being one of the first companies to use nanotechnology for improving Coatings properties. BYK invests approximately 7.5% of its earnings in R&D—three times more than the industry average.
RHEOBYK-R 606 is a liquid rheology additive for solvent-borne and solvent-free adhesives and sealants based on polyurethane, epoxy, and acrylate resins that contain pyrogenic silica or organophilic phyllosilicates.
BYK®-DYNWET 800 is a silicone-free surface additive for aqueous adhesives and sealants. It reduces the dynamic surface tension during fast application processes and thus improves subtrate wetting.
BYK®-1760 is an emission-free silicone and polymer-containing defoamer and air release agent for solvent-borne and solvent-free coatings, adhesives, sealants and casting resins. Particularly recommended for epoxy resin systems.
RHEOBYK-7590 is a powdered rheology additive for non-polar solvent-borne systems, powder coatings, adhesives and sealants. It is suitable for systems based on aliphatic non-polar solvents. The main fields of application are alkyd resin coatings such as ar...view more
RHEOBYK-7590 is a powdered rheology additive for non-polar solvent-borne systems, powder coatings, adhesives and sealants. It is suitable for systems based on aliphatic non-polar solvents. The main fields of application are alkyd resin coatings such as architectural coatings, glazes and general industrial coatings as well as protective coatings. view less

RHEOBYK-431 is a liquid rheology additive for solvent-borne coatings, adhesives, and sealants to improve anti-sagging and anti-settling properties. With the aid of the pigments and fillers, the additive generates a three-dimensional network structure. The entanglement of the high molecular weight polymers is responsible for the development of the pseudoplastic flow behavior.
The polarity of the system and the incorporation temperature influence the rheological effectiveness. The settling of the pigments and fillers is prevented and outstanding anti-sagging properties are produced due to the rapid rebound in viscosity after shearing. The additive has no "false body effect", no negative influence on the intercoat adhesion, and it is easy to process on account of its liquid form. view less
