BYK reports that its Viscosity Control Technology (VCT), based on two new process additives, opens up enormous value-added potential for manufacturers of epoxy resin systems.
The Thixbooster and Thixbreaker additives influence the properties of hydrophilic fumed silica particles, and thus help reduce or adapt the initial viscosity of high-viscosity two-component adhesives, sealing and putty materials, as well as protective coatings, which are used in components of wind turbines, rapid prototyping and other applications.
BYK-P 2710 (Thixbreaker) is designed for the epoxy resin and BYK-P 2720 (Thixbooster) for the corresponding amine hardener component. BYK says that thanks to their synchronised interaction, the two additives enable the creation of the optimum application viscosity from two low-viscosity components, resulting in formulations can be applied with the same layer thicknesses, yet more quickly and more easily than current systems. VCT is claimed to reduce the production time of the formulation by roughly half, while the production volume during the same period is doubled.
BYK notes that the low viscosity of the formulation also has logistical benefits. Instead of barrels, the liquid formulations can be transported in environmentally friendly IBC containers or in tanker trucks. This reduces transportation workload and costs.
Powertrains, be they conventional, hybrid or fully electric, will need to be light in weight if carmakers are to meet the stringent regulations on carbon dioxide emissions (CO2) to come into force in 2025 – and composites will be key to making this happen. This was the message highlighted at the Lightweight Composite Solutions Conference organised by Vyncolit and Sumitomo Bakelite Co Ltd and held in Gent, Belgium.
