Improved performance with reduced VOC Content

Composites

Evonik’s specialty methacrylate monomers are widely used as reactive diluents in vinyl ester (VE) and unsaturated polyester (UP) resins. The usage of styrene as a reactive diluent for VE and UP resins has recently come under increased environmental and regulatory scrutiny.

Specialty methacrylates for composite resins

Evonik’s specialty methacrylates product line offers a wide range of low-volatile and low-odor methacrylate monomers for full or partial substitution of styrene in composite resins. Crosslinkers are used as reactive diluents to improve the mechanical properties of low styrene content resins.

Alternatively, these crosslinkers can be used in combination with other methacrylate monomers, such as VISIOMER® BNMA, VISIOMER® c-HMA and VISIOMER® Terra IBOMA, to create low odor zero-styrene resins. Reactive diluent mixtures of the monomers allow for optimization of desired properties like elongation at break, tensile strength, heat deflection temperature (HDT) and water resistance.

Specialty methacrylates improve water resistance, tensile strength and elongation at break in composite materials for wind turbines.

VISIOMER® 1,4-BDDMA, VISIOMER® EGDMA, VISIOMER® PEG200DMA and VISIOMER® TMPTMA are used as reactive diluents to improve mechanical properties.

VISIOMER® HEMA-P is widely applied as adhesion promoter in applications like adhesives or coating resins, but it can also be used as co-reactive diluent in VE or UP composite resins. Evonik offers VISIOMER® HEMA-P 70M and VISIOMER® HEMA-P 100
