In theAbrasivesindustry, precise thermal control is essential for bond integrity, grain retention, product consistency, and stable continuous output. Both coated and bonded abrasives rely on carefully managed heating during resin application, drying, curing, and hot-press or furnace stages. In coated abrasives, the backing passes through curing ovens after the maker coat and again after the size coat to secure abrasive grains and complete resin crosslinking. In resin-bond abrasives, conventional grinding wheels are typically cured at150–200°C, while hot pressing for some superabrasive tools occurs around175–200°C. These process windows demand heat transfer fluids that circulate efficiently, maintain uniform oven and jacket temperatures, and remain stable through repeated heating cycles.EuroTherm 320 (E320)offers dependable-30 to 320°Cservice with9.8 mm²/s viscosity at 40°C, combining low-viscosity circulation, thermal stability, and cost-effectiveness for mainstream curing systems.EuroTherm 330 (E330)provides-49 to 315°Ccoverage,4.04 mm²/s viscosity at 40°C, and a-68°C pour point, supporting fast start-up and responsive control. For larger closed-loop systems,RÜTGERS Ruetaflex 1000 (R1000)extends performance to-55 to 330°Cwith6 mm²/s viscosity at 40°C, low-pour-point fluidity, and long service life, helping abrasive plants reduce downtime while improving safety and thermal consistency.
