Insulated Glass Sealants

Designed Polymers for

VESTOPLAST®   POLYVEST®


With its low water vapor permeability, its flexibility at low temperatures, its good UV stability and good adhesion properties, VESTOPLAST® is used in sealants for multi-glazed windows as well as in solar cells.
Hydroxyl-terminated polybutadiene (HTPB), which is being marketed under the trade name POLYVEST® HT by Evonik, is the major polymeric binder for high quality PU secondary window sealants for insulated glass units. Due to its low moisture and oxygen permeability and good compatibility with other components, POLYVEST® HT based secondary window sealants achieve highest quality standards.
