BYKのレオロジー剤は加工性の向上や優れた貯蔵安定性をもたらし、膜厚(フィルム)調整の機能を持つ製品もあります。レオロジー添加剤をお使いになると、幅広い用途で性能は著しく向上します。   しかし、要求性能を実現するためには、個々の解決策やレオロジー特性の最適な処方が必要になります。例えば、貯蔵安定性を高めるには層厚を増やすよりも異なった粘度性能が求められます。;低シェアでの粘度では、接触抵抗を高めるよりも別のアプローチが必要になります。   さらに、 添加剤は溶剤、無溶剤あるいは水系など極性に応じて最適な選択が必須です。   BYKは、様々な系や極性に対応が可能な添加剤の種類を取り揃えています。その中には層状タイプ、会合型シックナー、合成ヘクトライトのような高機能性添加剤もあります。相溶性や透明性が高いのが特徴です。液状レオロジー剤は添加が容易です。

Learn more about GARAMITE

GARAMITE rheology additives are organophilic phyllosicates based on the Mixed Mineral Technology (MMT) for solvent-borne and solvent-free systems. The GARAMITE organophilic phyllosilcates are based on the patented Mixed Mineral Thixotrope (MMT) technology and designed for usage in solvent-borne and solvent-free systems. They have an exceptionally high bulk density (i.e. lower volume), exhibit a very unique rheology profile, are easy to handle and incorporate, and give outstanding sag resistance and anti-settling properties. GARAMITE additives can be used in the most varied of solvent-borne and solvent-free systems such as coatings, plastics, adhesives and sealants, and household and institutional cleaners.
Key benefits
  • Rheology additives
  • Organophilic phyllosilicates based on patented MMT technology
  • For solvent-borne and solvent-free systems
  • Easy incorporation
  • Excellent improvement of sag resistance and anti-settling properties

Learn more about OPTIGEL

BYK´s OPTIGEL rheology additives are activated phyllosilicates for aqueous systems. The main function of all OPTIGEL products is the thixotropic stabilization of aqueous systems. Depending on the grade, a low to very high thickening effect and excellent anti-settling are achieved. They improve the processability and storage stability and provide anti-sag properties which allow for higher film thicknesses. There are unmodified and organically modified OPTIGEL types, whereby the latter show a high to very high thickening effect. As there are different types of OPTIGEL rheology additives available, it is possible to choose the matching product for various aqueous applications: coatings, adhesives and sealants, construction formulations, household, institutional, and industrial cleaners.
Key benefits
  • Rheology additives
  • Excellent stabilizing and anti-settling effect as well as sag control
  • Prevention of phase separation and syneresis
  • Stability of the gel structure over a wide temperature range
  • Improvement of processability
  • Modification adapted to the intended use
