Epoxy curing agents guarantee high durability of your composite pipes in all industrial applications, for instance in the oil and gas industry. This ensures extended maintenance cycles and a long service life.
VISIOMER® Specialty Methacrylates for CIPP Relining: Styrene-Free Reactive Diluents for Vinyl Ester Resins
Styrene has long been used as a reactive diluent, but due to its health and environmental risks, safer alternatives are needed. VISIOMER® Specialty Methacrylates from Evonik offer high-performance, low-VOC, and label-friendly solutions for styrene-free VE resin formulations in CIPP.
Key products include VISIOMER® 1,4-BDDMA, which enhances mechanical strength and water resistance, and VISIOMER® PEG 200 DMA, which adds flexibility and is label-free. Monoesters like VISIOMER® Terra IBOMA, a bio-based option with excellent thermal properties, and VISIOMER® BNMA, which improves rigidity and reduces the volatile organic compound (VOC) content, help fine-tune resin performance.
Replacing styrene in VE resins is not a simple one-to-one substitution. Instead, a carefully balanced mixture of mono- and di-functional methacrylates is used to achieve the desired viscosity, solubility, and crosslinking density. VISIOMER® methacrylates enable tailored, sustainable formulations for modern CIPP systems.
