Quartz Filled Epoxy System


Master Bond Supreme 45HTQ is a thermally stable, two component quartz filled epoxy system. It features  exceptional abrasion and chemical resistant properties. It will withstand  exposure to petrochemicals, acids, bases and solvents. It retains its  performance profile at elevated temperatures up to +450°F. Supreme 45HTQ has a 100 to 30 mix  ratio by weight and offers a working life exceeding 12 hours at room  temperature. It has good flow properties and is easy to apply for bonding and  sealing applications. This electrically insulative epoxy can also be cast in  sections many inches in depth. 

This high strength system bonds well  to a wide variety of substrates including metals, composites, ceramics and many  rubbers and plastics. It has a tensile strength over 10,000 psi and a compressive  strength greater than 20,000 psi at room temperature. Dimensionally stable, it  requires oven curing at 250-350°F and offers low shrinkage upon curing. As a  toughened compound, Supreme 45HTQ resists rigorous thermal cycling. Supreme 45HTQ is widely used in  downhole oil drilling applications. It is also frequently employed by the  aerospace, chemical processing, pump, mining, power and other industries. It is  available in a variety of standard packaging options including ½ pint, pint,  quart, gallon and 5 gallon  container kits. It has a 6 month shelf life at room temperature when stored in  original, unopened containers.
