Filler dispersion aid improves compatibility between materials

Organosilane technology specialist Dow Corning Corporation is introducing Dow Corning® Z-6173 filler dispersion aid, a multifunctional siloxane product that is said to improve filler dispersion, improve compatibility between materials, and provide application-specific benefits.

According to the company, other benefits of the product include: its ease of use, requiring no pre-hydrolysis or catalyst; low volatile organic compounds (VOC), generating lower levels of methanol than traditional, monomeric silane coupling agents; its ability to be used in wet and dry processes, either to pre-treat the filler or delivered in situ via liquid injection or absorption onto a carrier; and the increase in throughput it gives by lowering the viscosity of the molten compound in the mixer.

The product is suitable for use with a wide range of fillers including silica, mica, wollastonite, glass and natural fibres, talc, calcium carbonate, ferrous metals and carbon microfibres. Its alkyl functionality not only improves material compatibility but also acts as a hydrophobe to reduce water absorption.
