Unlock Superior Performance in Construction with POLYVEST®
POLYVEST® grades are used in secondary sealants for window glazing, in binder of dusty and dry quartz sand as well as in binder for soil stabilization. Moreover, POLYVEST® can be added as modifier to silicone sealants.
Window glazing and insulated glass sealants
Evonik provides high-performance solutions for both primary and secondary sealants in window glazing and insulated glass applications.
- Primary Sealants: POLYVEST® PO SG 206 is a silane-grafted amorphous polyolefin designed for durable and reliable primary sealants. It offers excellent adhesion, low moisture permeability, and long-term stability.
- Secondary Sealants: POLYVEST® HT is a hydroxyl-terminated polybutadiene (HTPB) binder optimized for polyurethane secondary sealants. It ensures low moisture and oxygen permeability, high compatibility, and superior sealing performance.

Large amounts of heat in buildings are lost through windows and doors. This presents a significant opportunity for more energy-efficient homes. In collaboration with our customer Kömmerling, we are working on state-of-the-art solutions. Learn more about energy-efficient windows and our partnership here.
Sand Filled Mortar
POLYVEST® serves as a high-performance binder designed for grouts used as fillers between paving tiles and various paving materials, including natural stones and concrete blocks.
Upon exposure to atmospheric oxygen, POLYVEST® reacts quickly to form peroxides and initiates a cross-linking process. This innovative formulation ensures rapid drying, exceptional bending and crushing strength, and excellent resistance to water, acids, bases, salts, and frost. Additionally, POLYVEST®-based sand-filled mortars effectively manage water penetration and provide robust weed control.
Bitumen Modification
The unfunctionalized POLYVEST® and the hydroxyl-terminated POLYVEST® HT contribute to reductions of viscosity as well as softening point of bitumen membranes by its typical characteristics. In addition, POLYVEST® HT in being incorporated as reactive component in bitumen systems.
