Applications
KH-171, is used as a polymer modifier via grafting reactions. The resulting pendant trimethoxysilyl groups can function as moisture-activated crosslinking sites. The silane grafted polymer is processed as a thermoplastic and crosslinking occurs after fabrication of the finished article upon exposure to moisture.
Packing and Storage
20KGS or 195 KGS plastic drum. Stored in a cool and dark place. Storage period is two years.
