3D-ADD RCC3 Reinforced Composite Concentrate for improving the mechanical properties and electrical insulation of 3Dresyns

Product description

3D-ADD RCC3 is an excellent Reinforced Composite Concentrate, supplied as a paste at high concentration of safe and natural based reinforcing fibers.

It can be added to 3D resins to improve their physical and mechanical properties and is designed for reinforced composite 3D printed materials requiring significant mechanical improvement.

Application framework

Designed for use in compatible SLA, DLP & LCD 3D resin systems as a reinforced composite concentrate for improving physical and mechanical properties.

Typical applications

• Reinforced composite 3D printed materials
• Improving physical and mechanical properties of 3D resins
• Applications requiring improved thermal conductivity without decreasing electrical insulation
• Applications requiring reduced dielectric permittivity and loss of dielectric crystalline phase for high frequency electronics

Measured mechanical properties

• Tensile strength: (ISO 527-1 / ISO 527-2)
• Flexural strength: (ISO 178)
• Young’s modulus: MPa (ISO 527)
• Elongation at break: (ISO 527)
• Shore hardness: (ISO 868)
• Notched Izod impact strength: (ISO 180)

Measured physical properties

• Mohs hardness: 5
• Low moisture absorption
• Thermal conductivity: 2.6-2.80 W/m °K of fiber filler
• Stable greenish grey paste / slurry
• Additions of 15-25% by weight are recommended to preserve printability in most SLA, DLP & LCD printers and provide significant mechanical improvement of 3D printed materials

Functional performance characteristics

• Tensile strength may increase up to 30%
• Flexural strength may increase up to 20%
• Flexural modulus may increase up to 60%
• Notched-Izod impact strength may increase up to 60%
• Improved thermal conductivity without decreasing electrical insulation
• Reduced dielectric permittivity and loss of dielectric crystalline phase for high frequency electronics

Processing and handling performance

• Easy to add and mix in any 3Dresyn
• Additions of 15-25% by weight are recommended to preserve printability in most SLA, DLP & LCD printers and provide significant mechanical improvement of 3D printed materials
• It is supplied as a kit, which contains the product, one graduated beaker and one empty 250 mL black bottle to measure, mix, keep and protect the 3D resins from daylight
• Please do not expose any 3D resins to natural or room light to prevent their curing.
• Step addtions are recommended to get the optimum and desired overall properties balance for each reinforced composite system.

Chemical and safety characteristics

• Eco friendly and ultra safe, based on natural raw materials
• Safe
• Organo-tin free

Testing & processing disclaimer

The effect on the mechanical properties will depend on the original properties of the chosen 3Dresyn and the dosage of the concentrate used. Step addtions are recommended to get the optimum and desired overall properties balance for each reinforced composite system.
