Dielectric Analysis

DEA is the most powerful measurement technique for the critical, invisible in-mold Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing that dictates the quality of a component.

You can measure the following:

• Degree of CureThe degree of curing describes the conversion achieved during crosslinking reactions (curing). Degree of Cure
• Gel-Point
• Flow Behavior
• Reactivity
• Cure Monitoring
• Diffusion Properties
• Glass Transition TemperatureThe glass transition is one of the most important properties of amorphous and semi-crystalline materials, e.g., inorganic glasses, amorphous metals, polymers, pharmaceuticals and food ingredients, etc., and describes the temperature region where the mechanical properties of the materials change from hard and brittle to more soft, deformable or rubbery.Glass Transition Temperature
• Process Monitoring and Optimization
• Aging
• Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. Decomposition Effects

To recreate real-world processing conditions, NETZSCH offers a wide variety of accessories and add-ons for the DEA 288 Ionic.

• A laboratory furnace with heating, cooling, and IsothermalTests at controlled and constant temperature are called isothermal.isothermal operation (-140 °C to +400 °C) that can be combined with a UV light source.
• A humidity/atmosphere chamber is available for testing materials under defined environmental conditions.
• A UV option (OmniCure^® S2000) is available for the software-controlled Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing of light-reactive systems, such as coatings, adhesives, and resins.
• A laboratory press (up to 350°C, 10kN) is available for testing composite or molding materials under simultaneous heat and pressure.
   

All accessories are fully integrated into the Proteus^® software, allowing for intuitive control and synchronized data acquisition, which bridges the gap between laboratory research and industrial production.

Dielectric Analysis (DEA), also known as Dielectric Thermal Analysis (DETA), is the most powerful method for investigating the invisible Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing processes of thermosetting polymers. 

By measuring changes in dielectric properties during a reaction, DEA delivers direct, real-time insights into Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing under true processing conditions and tracks ion mobility, viscosity, gel point and Degree of CureThe degree of curing describes the conversion achieved during crosslinking reactions (curing). degree of cure. 

Unlike DMA, DEA can follow Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing processes much longer — even after the sample is rigid — making it especially powerful for highly crosslinked systems.

Benefit from:

• Direct, in-situ measurements without complex sample preparation
• Real-time monitoring during processing (including in-mold)
• Applicable to thermal, UV, and dual-cure systems
• Wide frequency range for both fast and slow Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”.

• Portable and industrial versions available for lab and production use

DEA can be applied to a wide range of materials, including:

• Epoxy, polyester, and polyurethane resins
• Sheet and bulk molding compounds (SMC/BMC)
• Prepregs and composites
• Adhesives, paints, varnishes, inks
• UV-Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing systems

NETZSCH offers a wide range of disposable, reusable, and in-mold sensors tailored to different applications — from coatings and adhesives to thick composites and high-pressure molding processes.

Yes. NETZSCH offers both a portable lab version and a rack version for integration into industrial processes. In-mold sensors allow for direct monitoring of the curing behavior during manufacturing.
