In a world where durability, flexibility, and adhesion define product success, Evonik delivers the chemistry that makes sealants smarter. Whether you're formulating for construction, the automotive, electronics or industrial sectors, our additive technologies empower manufacturers to create sealants with controlled curing, adhesion and elasticity.
Evonik develops and sells tailored solutions that enhance mechanical properties and improve processing—because every seal matters.
Why Choose Evonik for Sealants?
- Proven Performance: Trusted brands like POLYVEST®, VESTOPLAST®, and TEGOSIL® deliver consistent results across diverse sealant systems.
- Mass-Balanced Options: POLYVEST® eCO 110 Bio, eCO 130 S Bio, eCO HT Bio and eCO MA 75 Bio are produced using the mass balance approach; POLYVEST® eCO 130 S Bio is described with a lower carbon footprint than the conventional grade.
- Tailored Innovation: Our portfolio includes catalysts, crosslinkers, modifiers, and inhibitors to fine-tune sealant performance.
Solutions by Application
Construction & Industrial Sealants
Used in joints, facades, and structural bonding where weather resistance and flexibility are key.
- POLYVEST® – Liquid polybutadienes for elastic sealants, available non-functionalized, hydroxyl-terminated, maleic anhydride-functionalized and methacrylate-terminated, as well as a silane-modified poly-alpha-olefin (POLYVEST® PO SG 206).
- VESTOPLAST® – Amorphous poly-alpha-olefins for hot-melt sealants and waterproofing systems.
- TEGOSIL® Crosslinker, Catalyst, Inhibitor – Additives that control curing speed and pot life in silicone sealants: SiH-functional crosslinkers, platinum catalysts for addition-curing systems and inhibitors for pot-life adjustment.
Automotive & Electronics
Applied in vibration damping, sealing gaps, and protecting sensitive components.
- TEGOSIL® Modifier, Polymer, VQM – Functional silicone components that enhance elasticity, chemical resistance, and mechanical strength. The range covers silanol-terminated polydimethylsiloxanes for condensation-curing systems, vinylfunctional polymers and VQM resin formulations for addition-curing systems, and reactive silicone plasticizers.
