HDK®H21 Dedication to Exceptional Performance

PublishTime：2024-08-29

The new HDK® H21 is an advanced hydrophobic pyrogenic silica for use in highly polar systems including epoxy, polyurethane, and vinyl ester resin systems. HDK® H21 is a polysiloxane treated grade with superior processing and performance properties, designed to provide the best dispersion, excellent rheology control, and prolonged storage stability. HDK® H21 complements our existing siloxane treated pyrogenic silicas – HDK® H18, which is optimized for high performance, and HDK® H17, which is designed for the best processing.
