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.
After the collapse of a drinking water pipeline in downtown Amsterdam, the Netherlands, Insituform was contracted to reline a close to 100 year old pipe underneath one of the canals. Water was restored successfully within five days, with minimal impact on traffic and the environment.
Lanxess’ Urethane Systems business unit (URE) is extending its collaboration with the Centre for UMass/Industry Research on Polymers (CUMIRP) at the University of Massachusetts Amherst, US. From October 2018 URE will additionally participate in Research Cluster M on Mechanics & Advanced Manufacturing of Polymers and Composites.
Sumitomo Chemical reports that its polyethersulfone (PES) micro-powder additive SumikaExcel 5003P boosts fracture toughness and resistance to micro-cracking for fibre reinforced epoxy composites over a broad temperature range without negatively impacting dimensional stability, flame/smoke/toxicity (FST), creep resistance, modulus, impact, or yield strength.
