POLYVEST® for Construction Applications

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.

Learn how our POLYVEST® makes windows energy-efficient

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.
