Difunctional monomers like VISIOMER® HEMA-TMDI deliver high mechanical strength through enhanced intermolecular bonding, high heat deflection temperature (HDT), and fast curing kinetics for rapid layer formation. It also contributes to improved toughness when combined with other hydroxyl-functional monomers. Composites for crowns and bridges, fillings and adhesives contain high molecular weight multifunctional methacrylates that show minimum shrinkage during polymerization, e.g. VISIOMER® HEMATMDI, as well as low-molecular-weight multifunctional methacrylates for viscosity adjustment, such as VISIOMER® TRGDMA. Dental applications also require monomers that can be light cured. Due to its reactivity, VISIOMER® HEMATMDI is one of the methacrylate monomers that is specifically dedicated to this application.
In acrylic dispersions, VISIOMER® MEEU and VISIOMER®HEMA-P protect metal surfaces in direct-to-metal applications and improve wet adhesion on wood substrates.

Evonik’s VISIOMER® Specialty Methacrylates, including VISIOMER® BNMA and Terra IPGMA, provide innovative, label-friendly and low-odor to nearly odorless alternatives. These monomers enhance user safety and comfort, support regulatory compliance by reducing VOCs, and are listed under TSCA and REACH. VISIOMER® BNMA, with its aromatic structure, contributes to enhanced thermal and chemical resistance—making it particularly suitable for demanding structural applications in automotive and industrial settings. For hydrophobic functionality, VISIOMER® Terra C13-MA, Terra C17,4 MA, and BNMA offer tunable adsorption, rainfastness, and flocculation control through varying degrees of hydrophobicity.

Composites for crowns and bridges, fillings and adhesives contain high molecular weight multifunctional methacrylates that show minimum shrinkage during polymerization, e.g. VISIOMER® HEMATMDI, as well as low-molecular-weight multifunctional methacrylates for viscosity adjustment, such as VISIOMER® TRGDMA. In anaerobic systems, VISIOMER® TRGDMA and VISIOMER® PEG 200 DMA are key dimethacrylates that ensure reliable crosslinking and long-term performance. VISIOMER® TRGDMA delivers excellent shear and temperature resistance, securing bonded parts even under harsh conditions.

Artificial teeth and dentures are manufactured using the monomer/polymer method. Here, formulations typically contain a certain amount of multifunctional methacrylates, e.g. VISIOMER® EGDMA. Multifunctional types such as VISIOMER® PEG 200 DMA or EGDMA enhance crosslinking and mechanical stability, making them ideal for vacuum processes.
