Product Details

Dynasylan® 4148 helps to control rheological properties and to reduce viscosity in highly-filled polymer systems, like aluminum trihydroxide-filled polyesters or SMC-pastes.

Contrary to most other organofunctional silanes, Dynasylan® 4148 features chemical polarity yet remaining chemically not reactive. Such a product is used as a hydrophilic compatibilizer rather than a covalent adhesion promoter.

Dynasylan® 4148 permits workable viscosities at well over 250 phr aluminum trihydroxide loading in unsaturated polyester resins. Further more, Dynasylan® 4148 can be used as anti-settling agent for corrosion inhibitors in glycol based cooling agents.

As a non-coupling silane Dynasylan® 4148 can also be used as a slipping agent to simply modify a surface.

Dynasylan® 4148 can be added neatly to a blend of filler or pigment and resin, or it can be used for the pretreatment of the filler or pigment.

BENEFITS

  • reduce the dispersion viscosity of aluminum trihydroxide and many other fillers and pigments
  • increase pigment dispersion
  • enhanced gloss
  • act as a lubricant and wetting agend in the glass fibre industry
