Dow Corning Offers
Solvent-Free Water Repellent
● Dow Corning Corporation’s new, solventfree
water repellent, Z-6689, has been
shown to bead on alkaline substrates
as quickly as five minutes after application,
allowing formulators to develop
products with outstanding hydrophobicity,
according to the company. The
silane/siloxane concentrate liquid, with
98% active ingredients, is effective at
very low active solid levels, which permits
a high dilution rate using organic
or silane-based solvents. More info: Dow
