Increase Water Repellency
Many plastics applications require excellent hydrophobic properties.
Moisture can affect part dimensions and mechanical properties, accelerate aging
and degrade performance of the end application. Unfortunately, not only do some
resins such as PA, polyester and PC absorb significant moisture, but many
fillers used in compounds are also highly hydrophilic.
Solving Your Application
Our additives boost water repellency in a range of applications, including
automotive under-hood components, kitchen appliances, electrical housings and
fuse boxes, power tools and wire and cable insulation.
Our hydrophobic improvement technology offers these additional benefits:
Maintains mechanical properties
Prevents premature aging
Improves dispersion and
de-agglomeration of inorganic fillers
Product highlights include:
Dow Corning® 11-100 Additive (PDF): Contains alkoxy and ankyl functional
groups on siloxane to transform hydrophilic resins and inorganic fillers into
Dow Corning® 4-7081 (PDF): silicone powders delivering
hydrophobization in typical highly filled HFFR compounds.
