使用流变助剂,可以极大改善很多体系的应用特性。

如需定制化解决方案和精准调节,视具体情况而定。例如:提高贮存稳定性所需的粘度不同于提高涂膜厚度;提高低剪粘度所需的方法也有别于提高耐洗刷性。

此外,助剂须精准适应体系极性,溶剂型、无溶剂型或水性,视情况而定。

毕克化学为不同体系提供各种助剂。除片状硅酸盐(膨润土)或缔合型增稠剂等类型,还提供合成片状硅酸盐等特殊的高性能助剂,非常均匀和透明。还有易添加的液态流变助剂及气硅增效剂,完善我们的产品范畴。

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
